THREATS TO NATIVE WILDLIFE SPECIES
----------
WEDNESDAY, JULY 8, 2009
U.S. Senate,
Committee on Environment and Public Works,
Subcommittee on Water and Wildlife,
Subcommittee on Oversight,
Washington, DC.
The subcommittees met, pursuant to notice, at 10 a.m. in
room 406, Dirksen Senate Office Building, Hon. Benjamin L.
Cardin and Hon. Sheldon Whitehouse (chairmen of the
subcommittees) presiding.
Present: Senators Cardin, Whitehouse, Lautenberg, Barrasso,
Crapo, and Gillibrand.
OPENING STATEMENT OF HON. BENJAMIN L. CARDIN,
U.S. SENATOR FROM THE STATE OF MARYLAND
Senator Cardin. The subcommittees will come to order.
Today we are having a joint subcommittee hearing of the
Environment and Public Works Committee of the Water and
Wildlife and Oversight Committees. I want to thank my colleague
and friend, Senator Whitehouse, for arranging for this joint
hearing with the Water and Wildlife Committee that I chair. He
chairs the Oversight Committee. And we want to thank Senator
Barrasso for his help in arranging this morning's hearing.
We are talking about the threats to native wildlife
species. And we are pleased that two of our colleagues have
joined us: Senator Levin, in talking about the threats to the
Great Lakes; and Senator Nelson, who will talk about the unique
wildlife and ecosystems in Florida and the python which he
brought, it looks like the skin, with him today to demonstrate
the danger to the ecosystems in Florida.
The threat to native wildlife comes from many sources.
Today we will be talking about two of those, one dealing with
invasive species, the other dealing with diseases.
The release of invasive species into the local environment
presents a real risk to our environment. The Burmese pythons in
Southern Florida have caused a major problem, and our colleague
Senator Nelson will be talking about that. In my own State of
Maryland, we have had the snakehead fish which has been
released that has caused major problems.
These are wildlife animals and fish that are just released
into the wild because they are mainly taken as pets, people get
tired, and then think they are doing a favor to release them to
the wild. They cause huge problems with the native wildlife.
We have a disease called white-nose syndrome in the
Northeast with the bat colonies. We will be talking about those
issues.
What we have done is try to manage these invasive species,
and that continues to be a great challenge. It is expensive,
and it is a challenge. In my own State of Maryland, we have
dealt with the nutria. The nutria is a furry animal that was
originally brought into Maryland and, I believe, also
Louisiana, because of its commercial value. They thought it
could be used, the skin could be used, for commercial reasons.
It was a commercial activity.
Well, it did not work very well, so they decided to release
the nutria to the wild. And in Louisiana and Maryland, it is
creating a huge problem. They literally eat the grasses and
destroy the wetlands that are critically important for the
ecosystems that are protecting the species as well as
eliminating the filtering system for the water quality. In the
Blackwater Wildlife Refuge, which is on the Eastern Shore of
Maryland, we have lost 5,000-plus acres of wetlands as a result
of the nutria. That has a direct loss to the local economy and
to the fisheries of $4 million per year.
Well, in 2000, Congress developed a public-private
partnership to deal with the nutria population, and it has been
somewhat successful. But there is more work that needs to be
done, and we will have a chance to talk about during today's
hearing.
I know that Senator Lautenberg will be talking about the
bats, a keystone species in the food web that help to control
insect and pest populations. They are vitally important to our
agricultural community in eating the bugs that would otherwise
feed on our crops. Well, there is a disease, white-nose
syndrome, which is causing us to lose a lot of our bat
colonies, and we are struggling to understand this disease. But
we do know that it is related to human activity, and we need to
talk about that.
We know that in certain animals and birds, they carry
diseases from imported animals and birds that can affect human
health, such as the West Nile and avian flues, just to mention
two by example.
Our first priority should be to prevent the introduction of
invasive species or diseases into America. I hope that during
the course of this hearing we will have a chance to talk about
our strategies as far as border control is concerned. Do we
have adequate laws that deal with animals and wildlife that
come into America? Do we need additional resources? It would be
far more productive to stop the problems at the border than
trying to clean up the problems once they get to our shores,
and I hope during today's hearing will have the chance to talk
about that.
I am pleased to call upon the Chairman of the Oversight
Subcommittee of the Environment and Public Works Committee,
Senator Whitehouse.
[The prepared statement of Senator Cardin follows:]
Statement of Hon. Benjamin L. Cardin,
U.S. Senator from the State of Maryland
I want to thank my colleague Senator Whitehouse for his
assistance in co-chairing this important hearing to examine the
threats disease and invasive species pose to the country's
native wildlife.
I also want thank our distinguished colleagues, Senator
Nelson and Senator Levin, for joining us today. Senator Nelson
is especially interested in addressing specific threats to the
unique wildlife and ecosystems of his home State of Florida,
and Senator Levin will be adding his perspective on the threats
to the Great Lakes.
We also want to thank our Agency and expert witnesses for
coming before our subcommittees.
The recent emergence of Burmese pythons in South Florida
and snakehead fish in the Chesapeake watershed are a direct
result of people who simply did not know better releasing these
invasive species into the local environment. White-nose
syndrome in Northeastern bat colonies, which we need to study
and learn more about, has had a devastating impact on these
native species.
These are just some of the numerous threats to native
species that motivated our subcommittees to examine a host of
both new and persistent diseases and invasive species
threatening the country's native wildlife populations. We hope
to learn what we are doing well and what we can do better to
curb these problems.
Managing the threat of invasive species continues to be one
of the greatest challenges facing U.S. Fish and Wildlife
Service refuge managers.
I know it has not been easy, but in some instances we are
seeing real progress. For nearly six decades at the Blackwater
National Wildlife Refuge in Maryland, nutria have been killing
wetland grasses that provide vital habitat for native
shorebirds, muskrats and blue crabs, not to mention the role
these grasses play in maintaining water quality.
Nutria are responsible for the loss of more than 5,000
acres of wetlands in the Blackwater refuge alone. The loss of
these wetlands, that are vital to the fishery, was estimated to
cost Maryland's economy nearly $4 million annually.
In 2000, Congress established a Federal funding source to
develop a public-private partnership program to address nutria
in Maryland. The partnership has implemented a successful
effort to manage the species. Healthy wetlands are returning to
places where nutria have been removed. But the job is not yet
done.
Bats are a keystone species in the food web that help
control insect and pest populations. They are vital to
agricultural food growers by eating bugs that feed on crops.
Since 2006, hundreds of thousands of hibernating bats have died
from white-nose syndrome. Without bats we face the real
possibility that certain insect species could boom out of
control, threatening crops as well as human health.
State wildlife managers are struggling to understand the
full nature of the disease. This struggle is further hampered
by the lack of capacity and resources wildlife managers have to
work with.
The spread of the disease to such a wide range of locations
may be linked to human activity. Exploring caves that have
infected bats may inadvertently be spreading the fungus. The
rapid spread and the rate of morbidity caused by white-nose
syndrome requires rapid action be taken.
West Nile and avian flu are examples of imported exotic
animal diseases with strains that can infect humans.
Our panelists have been on the front lines doing the
research and implementing programs on the ground to address
these problems. You know what works and what does not work when
it comes to stopping the spread of established diseases and
invasive species. I look forward to hearing your
recommendations. We all know that an ounce of prevention is
worth a pound of cure, so I hope our witnesses will focus on
how to stop these threats rather than simply discuss ways to
manage them.
Consideration must be given to preventing the next nutria
or snakehead invasion and keeping animals infected with the
next avian flu from ever reaching the U.S. in the first place.
OPENING STATEMENT OF HON. SHELDON WHITEHOUSE,
U.S. SENATOR FROM THE STATE OF RHODE ISLAND
Senator Whitehouse. Thank you very much, Ben. I am
delighted to join you in this hearing. I appreciate your
leadership in convening it.
I welcome Senator Carl Levin of Michigan and Senator Bill
Nelson of Florida here, who will be our opening presenters. I
appreciate very much that you have taken the trouble to attend,
and I am glad to be joined by so many colleagues here.
This is a significant issue. Two factors drive it. One is
global commerce, and the other is a changing climate. And
whether, as Senator Cardin indicated, the invasive species are
ones that are brought in lawfully and then escape into the wild
and acclimate themselves to this new environment, or whether
they are hitchhikers on the stream of global commerce and come
with shipping and packaging inadvertently and make their homes,
or whether they simply find that as climate changes they are
able to expand into new areas where we have not experienced
them before, it creates very significant issues. And I am very
pleased to participate in this hearing.
I want to mention that a very prominent Rhode Island
environmentalist, John Torgan, is here and will be presenting
in the second panel, and I look very much forward to his
participation.
I have to warn everybody that I am in my waning days on the
Health Committee and we are marking up the healthcare bill as
we speak. So, I will be in and out of the hearing. But I
appreciate very much and take a keen interest in the topic that
you have brought to our attention, Senator Cardin.
Thank you.
Senator Cardin. Thank you.
Senator Crapo, the ranking Republican on the Water and
Wildlife Subcommittee.
OPENING STATEMENT OF HON. MIKE CRAPO,
U.S. SENATOR FROM THE STATE OF IDAHO
Senator Crapo. Thank you very much, Mr. Chairman, and I
appreciate the fact that both of our Chairmen here have called
this joint hearing and are bringing attention to this important
issue.
As you have already well indicated, Senator Cardin, this is
a very, very critical issue in I think probably all 50 States
where we face the question of what kind of management we need
to undertake to effectively deal with invasive species. And
Idaho is certainly one of those States that has its share of
issues.
In Idaho, a number of the problematic invasive species are
things like the yellow star thistle, the quagga mussel, cheat
grass, bark beetles and your Asian millfoil, to name just a
few. One of these issues that we have in Idaho is that, because
such a large percentage of our State is owned by the Federal
Government, it is more than half, closer to two-thirds of our
State is Federal land, the activities and enforcement of the
Federal Government and the agencies that manage these lands are
critical to our ability to control and manage these invasive
species.
So, among the many other different types of issues that we
face, one of them is simply the interaction at the different
levels of government, between State and Federal, as well as
local governments, to deal with this and, frankly, the private
citizens as they have responsibilities as well.
Again, I thank you for your attention to this. I know there
is legislation in several different forms being considered that
can significantly change the way that we are approaching these
efforts to control invasive species, and I have not yet reached
a conclusion in my own mind as to whether the proposed changes
are going to be an improvement or not. But it is important for
us to evaluate these proposals as you are doing here today and,
again, I appreciate your bringing attention to these issues.
Senator Cardin. Well, thank you.
Senator Barrasso, the Ranking Republican on the Oversight
Committee.
OPENING STATEMENT OF HON. JOHN BARRASSO,
U.S. SENATOR FROM THE STATE OF WYOMING
Senator Barrasso. Well, thank you very much, Mr. Chairman,
for calling this important hearing. I am very pleased that we
are going to be here today discussing invasive species and the
impact on native wildlife. I welcome our guests as well.
In Wyoming, just as in the other States we have heard
about, we do have a number of invasive species issues.
Saltcedar and Russian olive trees severely impact water
availability for farmers along the North Platte River. Cheat
grass, juniper and other invasives threaten the sage brush
ecosystem that our sage grass depends upon. Our State is also
on the watch for the potential threat of zebra mussels, which
is a problem I already know is plaguing the Great Lake States.
Noxious species are also a threat on native species in Wyoming.
Wyoming faces an urgent problem, as they do in Idaho, for
the bark beetle infestation. In the Medicine Bow National
Forest, almost a half-million acres of these trees are infected
already by bark beetles. We have over 9 million acres of
national forest lands in Wyoming, and a Forest Service analysis
shows this epidemic doubled in size between 2007 and 2008.
These beetles destroy our forests and leave nothing but
dead timber standing in the wake. This represents a clear and
present threat to public land users, to communities, and to
homeowners. We have mountains of kindling just waiting to burn.
This is not a safe situation for the communities in and around
these mountains. So, we must go into the forests, remove some
of this dead timber, and reduce the risk of catastrophic fire.
The threat to our forests and the species that inhabit
those forests are very real for Western States, and more must
be done to address this threat.
Now, in terms of regulating invasive species from foreign
countries, I do have a number of concerns. We have a very
limited number of resources available. We need to put those
resources where they will do the most good. We have laws on the
books that regulate the importation of species. We need to make
sure that the funding is there to ensure that these laws are
properly enforced and that the agencies are properly staffed. I
would not want to pass additional legislation that would in any
way hurt our economy, including our pet economy, our sport
fishing economy, or our farming industries.
Let us not forget that, historically, the majority of
livestock and crops in the United States are non-native species
to North America. Many breeds of cats and dogs are non-native
to the States, as are many of the breeds of fish that we use to
stock our lakes, our reservoirs and our ponds for sport
fishing. So, to this day, species are brought from overseas for
these and other industries.
Most of these species, if left unchecked and not properly
managed, can cause significant damage to the surrounding
ecosystem. These species have been vital to key industries in
our economy and to pet owners and recreationists across the
country.
I am looking forward to the testimony today. I have a very
open mind on this and thank the Chairman for holding the
hearing.
Senator Cardin. Thank you very much.
Senator Crapo.
Senator Crapo. Mr. Chairman, I just wanted to indicate that
I, too, have another hearing right now, a climate change
hearing in the Finance Committee, so I will also be moving back
and forth.
Senator Cardin. I pointed that out, that I know members
will be coming in and out because of the commitments for other
committees, and every member's opening statement will be made
part of the record.
Senator Lautenberg.
OPENING STATEMENT OF HON. FRANK R. LAUTENBERG,
U.S. SENATOR FROM THE STATE OF NEW JERSEY
Senator Lautenberg. Thanks, Mr. Chairman.
When you see our colleagues here from other States, from
Western States as well as those of us from the Eastern side,
joining together, we know that we have a problem of serious
magnitude. I appreciate greatly your holding this hearing about
threats to animals and ecosystems across the country from
changing climate, vanishing habitats and invasive species.
Now, as you know and mentioned, and I appreciate it, I am
particularly concerned about a threat that could wipe out an
entire bat population from New Hampshire to Virginia. One might
react less concerned about bats. They are typically thought of
as an ugly little thing that is often rabid. But nothing could
be more invalid.
The threat to their population is a fungus called white-
nose syndrome. Since it first surfaced in 2006, it has spread
from cave to cave, leaving 90 to 100 percent of bat populations
in some caves dead or dying. And since bats are slow breeders,
scientists fear that the white-nose syndrome could cause many
bat species to go extinct. Over the last two winters, more than
1 million hibernating bats have died.
Now, at one bat cave in New Jersey, the Hibernian Mine,
which I entered for my own familiarization with that
population, there are normally 30,000 bats hibernating. As of
April, this past April, only 750 bats were found alive there.
The thing that struck the great alarm was the number of dead
bats lying all over the place.
We have got to stop the spread of this disease. We are
dealing with a major threat to an entire ecosystem, potentially
able to cause major environmental and economic problems, as my
colleagues have discussed, with their non-invasive species.
This is not a non-invasive species, but the disease is a
threatening one to that particular species.
Bats are on the front line of defense in protecting the
public's health and our crops. They prey almost exclusively on
insects, such as mosquitoes, which spread disease, and moths
and beetles as well, which damage crops. A single bat can
easily eat more than 3,000 insects in a night, and an entire
colony will consume hundreds of millions of insects. It is said
that a single bat will eat enough insects to be half its
weight. So, it is a pretty voracious and very important
species.
Bats also reduce the needs for pesticides which costs
farmers billions of dollars every year and can be harmful to
ourselves. With fewer bats, there are more mosquitoes to breed
disease, more insects to destroy the crops grown on New
Jersey's farms, threatening the livelihood of our farmers, and
damaging our economy.
And the problem is not limited, as you know, Mr. Chairman,
to New Jersey. This serious threat to our health, environment
and economy is repeating itself all along the East Coast. We
need to act fast, and we need help from the Administration.
In May, along with Senate and House colleagues, I sent a
letter to Interior Secretary Ken Salazar requesting emergency
funding for research into the cause of white-nose syndrome, and
to develop a solution to stop its spread. I look forward to the
Secretary's response.
Now, some of the witnesses on this panel have experienced
fighting the spread of diseases like white-nose syndrome and
helping species survive such threats. I look forward to hearing
their ideas on how we can save the bat population in New Jersey
and nationwide. Much is at risk. And the bats have become more
beautiful as we learn more about them.
Thanks very much, Mr. Chairman.
Senator Cardin. Thank you.
Senator Gillibrand.
OPENING STATEMENT OF HON. KIRSTEN GILLIBRAND,
U.S. SENATOR FROM THE STATE OF NEW YORK
Senator Gillibrand. Thank you, Mr. Chairman.
I appreciate the remarks of my colleague from New Jersey.
The issues that we are addressing today are about invasive
species. But the reason why it is so important is because it
fundamentally affects our economy, it fundamentally affects our
health and well being, and it fundamentally affects the costs
of having to address these invasive species at a time when we
have record high unemployment and enormous burdens on our
municipalities and towns and local governments.
When they have to address some of these invasive species,
those are costs that will have to be spent on addressing the
invasive species as opposed to other priorities that we have.
So, these are significant issues for our economy.
I will start with the white-nose bat syndrome. One of the
reasons why it is so important, just as Senator Lautenberg
said, is that because bats eat mosquitoes, in particular, and
other insects, they are very important to keeping our
communities safe.
One of the biggest threats we had around New York State was
the West Nile virus and I watched in many, many towns, where we
sprayed towns to kill mosquitoes to prevent our children from
getting the West Nile virus. It was a significant expense for
local municipalities and local towns.
Without the natural order of things, the natural life
cycles and many of the roles that bats and insects and other
species play, if we do not have the natural order of things,
there is much in disarray and it creates enormous expense and
risk. So that is one area.
The second area is that bats also help pollination, and
that brings to mind another problem, the colony collapse
disorder. The bee populations are being seriously decreased,
all across America and the world. In fact, 36 percent of bee
colonies were reported to be wiped out in the United States
because of the colony collapse disorder.
If you do not have bees, and you do not have bats, you do
not have pollination. If you do not have pollination, you do
not have fruits and vegetables in America. If you do not have
fruits and vegetables in America, we have a serious national
security risk to our food chain or our food supply. These
issues are critical to America's safety, from an agricultural
safety perspective, a national security perspective, and an
economic perspective.
We also have other great costs in New York State because of
some of our invasive species because we have so many natural
resources in our lakes. We have the Great Lakes, we have the
Adirondack Lakes, we have lakes all across New York. And a
number of the species are particularly threatening to our
economy of tourism in these lakes.
Whether we are looking at millfoil, which was mentioned by
my colleague Mr. Barrasso, or zebra mussel, what these kinds of
invasive species do is go so far as to clog drainage pipes, to
clog intake pipes, to clog damns, to really affect tourism.
Those are all of significant importance to our communities for
our clean water and for economic growth for our communities.
So, many of these invasive species must be addressed.
And the last group that I would like to just touch on is
some of those that affect our timber industry. We have the
Asian longhorn beetle and we have the cyrus wood wasp. Both of
them are extremely expensive to eradicate. But they must be
eradicated because, if they are left unchecked, they will
destroy the timber industry, they will destroy a lot of our
forestry, which will undermine many other economic issues like
tourism.
For example, the Asian longhorn beetle, it has cost more
than $180 million to eradicate it in the suburbs around New
York City so that it does not spread toward the Catskills and
the Adirondacks where it could be devastating to our tourism
and timber industries.
So, I am very appreciative of this hearing because, you
know, these are very serious economic, health and agricultural
impacts that affect not only the livelihood of New Yorkers, but
the health and well being of our children.
I appreciate your focusing attention on these very
important issues.
Senator Cardin. Well, I think each of the members' opening
statements points that we have a common challenge around the
Nation on dealing with the protection of our native wildlife
species, and we look forward to trying to work together to
figure out what we can do in a constructive manner.
Our first panel includes two of our colleagues that are
very actively involved on this issue, Senator Carl Levin from
Michigan who has been a leader in regards to the Great Lakes,
and Senator Bill Nelson from Florida, who has been very
actively involved in the Everglades and preserving those
issues.
Senator Levin.
OPENING STATEMENT OF HON. CARL LEVIN,
U.S. SENATOR FROM THE STATE OF MICHIGAN
Senator Levin. Thank you, Chairman Cardin and colleagues,
for inviting us to testify very briefly and to make an
introduction.
As the Chairman mentioned, I represent Michigan, a Great
Lakes State. Invasive species have done severe damage to our
Great Lakes as well as to the land mass of Michigan. Everything
from zebra mussel, which a number of you have mentioned, to the
emerald ash borer which are destroying ash trees. We have 180
invasive species identified in the Great Lakes alone.
I was thinking about bringing in a zebra mussel, by the
way, but then I had word that Senator Nelson might bring in an
exhibit which would make our poor zebra mussel look so puny by
comparison that you would think it would not be a problem.
[Laughter.]
Senator Levin. Let me just mention, I am not going to tell
this panel and these two subcommittees about the problems of
invasive species. You all know them. You have them in your
States. You have all made reference to them in your opening
statements. I just would reinforce one point that you made,
which is the universality of the problem, at least in terms of
all of our States.
The zebra mussels started in the Great Lakes. Thirty States
are now infested with zebra mussels. Like global warming, these
things do not stay in one place.
Second, the solution, at least one of the key remedies,
lies in your hands. That is to adopt a significant ballast
water treatment technology requirement for our ships. Most of
our invasive species in the Great Lakes States come in through
the water. In the ballast is our invasive species that come in
from other places. And when that ballast is exchanged in the
Great Lakes, it drops these invasive species in the Great
Lakes, including zebra mussels.
You had under your consideration, as has the Commerce
Committee had under consideration for many years, bills which
would require ships to have new technologies to destroy the
species instead of just being to remove or transfer ballast
from saltwater to fresh water and so forth. We actually have a
technology to destroy the species.
There has been a conflict in two bills. One bill, which I
think has been favored by many members on this committee and
these two subcommittees, basically would allow the States to
adopt a higher technology over the years than the national
standard which we would start with.
The Commerce Committee, and I do not want to generalize
here because I am not sure it applies to every member, but in
general, there is a Commerce Committee bill, I will identify
it, which says we are going to have a national standard, and we
are then going to let that standard apply for a reasonable
period of time without the shipping companies facing the
possibility that States will up the ante.
This is a traditional conflict. It is the not the first
time that we have faced this kind of a conflict. We have it all
the time. But it needs to be resolved. And I believe the right
resolution is for us to adopt a tough national standard, and
then to give the shipping industry a period of repose. They
will be guaranteed that there will not be any increase in that
standard for a reasonable period of time.
That is not the bill which many members of this committee
have favored. But that is the conflict that needs to be
resolved. I have taken a position on it which is, by the way,
different from the position I think of my own legislature,
which would like the State to be able to have a higher standard
a year from now. You have shipping companies put in expensive
technologies this year, and then a year from now any one of the
States can say, whoops, there is a new technology and we want
you to adopt a new one?
We are never going to get this accomplished unless we adopt
a national standard and let it stick for a reasonable period
time, whether it is 5 years or 10 years. I would urge the
members that are considering this to consider that option. But
it is in your hands. This conflict needs to be resolved between
these two bills. And again, the position I have taken is not my
own State legislature's position.
Having said that, I am really here to make an introduction,
not to lobby my colleagues.
I want to introduce a panelist who will be on the second
panel, Rebecca Humphries. She is the Director of the Michigan
Department of Natural Resources. She worked her way up through
the ranks of the Michigan of Natural Resources. She has more
than 30 years' experience in the field. She has considerable
knowledge on the impacts of invasive species and disease on
native wildlife. She has served, in recent years, as Chair of
the Fish and Wildlife Health Committee of the Association of
Fish and Wildlife Agencies.
So, she has a lot of information. She has tackled issues in
Michigan involving invasive species such as VHS, chronic
wasting disease, emerald ash borer and so forth. She is going
to have a lot of valuable information for these two
subcommittees that meet today.
We are grateful for your doing what you are doing. I know
that you are going to excuse me, and I appreciate that.
I have talked to Senator Nelson about his testimony and I
agree with everything that he says, for what that is worth. And
I am glad this damn python is a long way from where we live.
[Laughter.]
[The prepared statement of Senator Levin follows:]
Statement of Hon. Carl Levin,
U.S. Senator from the State of Michigan
Thank you, Chairman Cardin and Chairman Whitehouse and the
members of your subcommittees, for holding today's hearing on
the very important topic of threats to our wildlife.
As a Senator from Michigan, a Great Lakes State, I have
seen the consequences of allowing aquatic invasive species to
enter our waters. About 180 non-native organisms have been
identified already in the Great Lakes. Some of my colleagues
may remember that back in the late eighties and nineties, the
zebra mussel was released into the Great Lakes through ballast
water. At that time people considered the zebra mussel to be
just a problem for the Great Lakes. Today, almost 30 States are
fighting to control and prevent them. Zebra mussels can
significantly change the nature of the lake bottom, affecting
fish habitat and spawning. They trap nutrients and disrupt the
normal flow of these nutrients into deeper waters. The mussels
also excrete nutrients creating an environment that may be
linked to water quality problems, such as algal fouling on
rocky shorelines, off-tastes in drinking water and lethal
outbreaks of botulism in wildlife, especially during warm water
periods. Mussels eat by filtering algae from the water. This is
the same food source for many native fish which means less food
available to native species. Zebra mussels have caused drastic
declines in the native Great Lakes mussels (commonly called
clams) not only by competing for food, but also by nesting on
top of exposed clamshell so that the native mussel cannot get
enough food to survive.
Because invasive species can quickly spread throughout the
country, the best effort that we have against invasive species
is prevention. Maritime commerce is the largest pathway for new
species to be introduced into our waters, and I believe that we
need to enact legislation that will require ballast water
discharge management that will result in ballast water
treatment technology onboard ships as soon as possible. I
support establishing a strong national ballast water technology
standard for all ships. Technology that meets this standard
would be approved for a minimum period of time--5, 8, or 10
years.
I also believe it is important to address other pathways of
introduction such as intentional introductions. Right now,
anyone can order almost any organism on the Internet and have
it shipped into the U.S., and no one considers whether that
organism is invasive and harmful. We need to establish a
process to screen incoming organisms. The Great Lakes
Collaboration Implementation Act, which I and Senator Voinovich
introduced, establishes a screening process for invasive
organisms.
Third, we need to be more aggressive about adding organisms
that are invasive and injurious to the Lacey Act list. Listing
a species as injurious under the Lacey Act would prevent the
intentional introduction of these species by prohibiting the
interstate transportation or importation without a permit. One
species that I believe should not be imported is the bighead
carp, and I will introduce legislation to list the bighead carp
as injurious under the Lacey Act. Three other species of Asian
carp have already been listed. The Asian carp grow very big,
reproduce quickly, and are now the most abundant fish in the
Mississippi River. It's important to Michigan to prevent these
fish from entering the Great Lakes and destroying the native
fishery.
Mr. Chairmen and Ranking Members, the impact of invasive
species on Michigan's native wildlife is large. I am only able
to touch on a few of the invaders that have had such a negative
impact to my State, and I know that each of your States is also
suffering. So I encourage this committee to support legislation
to implement a strong ballast water management program, to
create a screening process for live organisms being imported
into the country, and to simplify the process of listing a
species as injurious under the Lacey Act.
And now I want to say a few words of introduction about
Director Rebecca Humphries, the Director of the Michigan
Department of Natural Resources, who will testify later on the
third panel. Director Humphries has worked her way up through
the ranks of the Michigan DNR and has more than 30 years of
experience in the natural resources field. She has considerable
knowledge on the impacts of invasive species and disease on
native wildlife. Over the last few years, she has served as the
chair of the Fish and Wildlife Health Committee for the
Association of Fish and Wildlife Agencies helping to develop a
package of information related to State and Federal authorities
to manage diseases in fish and wildlife so that when a disease
outbreak occurs, State agencies are prepared with plans, well
trained staff, and legal authorities. Director Humphries has
tackled issues in Michigan such as viral hemorrhagic septicemia
(VHS), chronic wasting disease, emerald ash borer, and I
believe that she will have some valuable recommendations on how
the Federal Government can work with States to minimize the
threats to native wildlife. Thank you, Director Humphries, for
coming to Washington to share your insights into these issues.
In closing, I want to thank the members of the two
subcommittees for today's hearing as well as the other
witnesses.
Senator Cardin. Senator Levin, thank you very much for
sharing your thoughts on the subject with us. We appreciate
your testimony.
Senator Nelson.
OPENING STATEMENT OF HON. BILL NELSON,
U.S. SENATOR FROM THE STATE OF FLORIDA
Senator Nelson. Mr. Chairman, while Senator Levin is still
here, I just want to say that I am a sponsor of that bill in
the Commerce Committee.
This mussel, this zebra mussel, is really a problem. What
happens is, instead of using rocks like they did in the old
days for ballast on ships, they use water. They take this water
from a foreign land. Well, this water is invaded with all of
these species, and they come into the Great Lakes and they dump
the water, and then the species get out. This zebra mussel goes
and attaches itself to drain pipes and so forth, and it
completely clogs up everything.
So, it is just another example that the Congress of the
United States needs to address this problem in law. It needs to
address what I am going to show you in law as well. And there
is something that you can do about that, and that is the bill
that we filed which adds to the List of Injurious Species the
Burmese python.
Now, let me tell you how bad this has become in the Florida
Everglades. These snakes that people import into this country
and buy as pets, well, a Burmese python can grow as much as 7
feet in 1 year. So they get them as these little bitty snakes,
and then they get too big, and people release them. And they
are so prolific.
As a matter of fact, in an environment like the Florida
Everglades that, by the way, the U.S. Government is spending a
lot of money, along with the State of Florida, to reform the
Florida Everglades from the diking and draining that had
occurred for the last three-quarters of a century, and now we
are allowing a species to take over that is at the top of the
food chain, and all of the natural species that is in the
Florida Everglades that we are restoring back to what Mother
Nature intended, all of that native species is being thwarted.
For example, they found that this snake has swam across the
ocean to Key Largo. It is the top key in the chain of the
Florida Keys. And there they found, in the belly of one of
these snakes, the endangered Key Largo wood rat. They have
found in these snakes a full grown Florida deer. They have
found a full grown Florida bobcat. It is only a matter of time
before a Florida Panther is found inside of one of these
invasive pythons.
As you can see, by the size of this critter, you can see
that this one is probably 16 or 17 feet, what they do is they
have fangs that have fish hooks on them. Their modus operandi,
since you cannot see them, they will lie in wait perfectly
still for their prey. They then strike, and grab their prey
with their fangs which, because it has a barb on the end, the
prey cannot pull away, then immediately wrap their constrictor
body around the prey and suffocate their prey to death.
Unfortunately, the worst happened last week in Florida. A
pet Burmese python only 8 feet long, not this long, slithered
out of its glass cage and, in the middle of the night, worked
its way up into the baby crib, attached its fang to the head of
a 2-year-old child, wrapped its body around the child and
strangled the child to death.
This happened in Sumter County, which is to the west of
Orlando and north of Tampa. It is just a matter of time before
one of these snakes gets to a visitor in the Florida
Everglades.
Mr. Chairman, I have had the Superintendent of the
Everglades Park tell me that they now estimate that these
snakes have proliferated to the tune of 150,000 in the Florida
Everglades National Park. The reason they are so prolific is,
they killed a 16-footer and inside of her were 56 eggs ready to
hatch. So, you see how it has become such an invasive species.
And it is taking over anything that is natural to the Florida
Everglades.
Now, fortunately, at the end of May, we took Secretary
Salazar down the Everglades, took him out in an airboat and he
got to see this natural phenomenon called the River of Grass.
But before we took the tour in the airboat, we brought this, it
is a 16-footer, you can see the body, and you can see Secretary
Salazar here looking at this snake. This snake is about as
large as this one. And you see the power. It took three men to
hold that snake and that snake was not hungry. You can see the
power.
The middle of that snake, the middle of him, is this big
around. And it is all muscle. You have heard the phrase a pig
in a python, with the hump in the middle of the snake? Well,
that is exactly what they do. Once they have suffocated their
prey to death, then these jaws separate and they ingest the
whole prey and the body expands and that is where the phrase
the pig in the python came from.
In the food chain, there is only predator that is higher
than this, and that is the alligator. But that is only a very
large alligator. We have had a 12-foot python attack an 8-foot
alligator. And they thrashed around in the water for 30 hours
right off of the headquarters of the National Park in the
Florida Everglades.
We have found a 6-foot alligator inside of a python. Here
again, this is only a 6-footer, and you can see what they look
like against St. Augustine grass, but when these critters get
into the natural swampy conditions, you cannot find them. They
had captured one, they put an electronic chip in one. So they
trapped it and they had the electronic antenna saying that the
snake is right there, and all of the biologists standing around
could not see the snake. That is how difficult they are.
What I am going to enter into the record, with your
permission, is a 10-page document that will detail the number
of python attacks on human beings in the last 10 years. And I
can tell you, Mr. Chairman, it has been 17, and 7 people have
died as a result of the attack.
So not only do we have a species that is threatening to
humans, and the superintendent of the park told me one day that
he has never experienced anything like this, they saw a python
starting to come across the road out in the park. He said his
attention was diverted momentarily and he turned around and the
python was right in front of him. They move that quickly.
So, endangerment to humans, especially endangerment to the
natural ecological phenomenon of what Mother Nature intended
because of this snake going after all the other prey, and,
ultimately, changing the very nature of something that we are
trying to return to what Mother Nature intended, and that is
the Florida Everglades.
I would close with this. This snake coming out of Burma,
all it knows is that it likes moist, humid climates. This is
not restricted just to the south end of the peninsula of
Florida. This snake, if it continues to proliferate, you are
going to find it all over the southern United States and that
is all the way, and the biologists will tell you as they
testify, there are conditions in California and all across the
sunbelt that are conditions for this snake to prosper in.
As you look at these invasive species, and there are plenty
of others you all have mentioned, and I would add that the
Brazilian pepper plant and the Nile monitor lizards are other
invasive species, we have got to have the ability to stop it.
Because we have the problem in Florida, I have been asking
the U.S. Fish and Wildlife Service, administratively, to do
something about the import. And for 3 years they have not. They
said that they are studying it. I am hopeful now that, under
Secretary Tom Strickland, who was down there with us, I am
hopeful that they are going to administratively get into it.
But you can do something about it, Mr. Chairman, by a one
word change in the law and restricting it to, not all of the
constrictor snakes, but to this particular one. And that would
be the help that we need to address this problem.
Thank, you, Mr. Chairman.
[The prepared statement of Senator Nelson follows:]
Statement of Hon. Bill Nelson,
U.S. Senator from the State of Florida
Chairman Cardin and Chairman Whitehouse, thank you for
inviting me to testify at this hearing today.
Last week tragedy struck in a small town northwest of
Orlando, Florida. As the family awoke a scene of horror
unfolded. An 8-foot albino Burmese python escaped from its
container, slithered through the house and up into a crib where
2-year-old Shaiunna Hare lay asleep. The snake bit the child
and wrapped itself around her body. By the time the paramedics
had arrived, the child was already dead from asphyxiation. This
is truly the scene of a parent's worst nightmares.
We have been warning about the dangers that these lethal
snakes present. I have a 10-page document that I will submit
for the record detailing python attacks over the last 10 years.
During that period at least 17 people have been the victim of
an attack, of which 7 died as a result.
Besides posing a threat to safety, invasive species like
the Burmese python are wreaking havoc in our most treasured
environments. Some estimate there are upwards of more than
100,000 of these deadly pythons in the Everglades National
Park. The crown jewel of our national park system has been
transformed into a hunting ground for these predators.
When is the time for action? We already have one tragedy on
our hands. How long will it be before one of these snakes gets
a hold of the extremely endangered Florida Panther? How long
will it be before a tourist in the Everglades National Park has
a dangerous encounter with one of these massive pythons? It
took this tragic event to bring back focus to this problem, but
there is something we can do about it.
The Fish and Wildlife Service has the capability, under
law, to declare this an injurious species under the Lacey Act.
After the South Florida Water Management District made a
request in June 2006, Fish and Wildlife has spent the last 3
years studying it. I think that Secretary of the Interior Ken
Salazar will take them from studying this issue to acting on
it. But there is something else we can do. Congress can change
the law.
I filed a bill in February which amends the Lacey Act and
declares pythons as an injurious animal. This will halt the
importation and interstate commerce of these deadly snakes.
Classifying the Burmese python or python molurus bivittatus as
an injurious animal would also stop the importation of these
snakes between States. This is of particular importance--while
Burmese pythons have already established a breeding population
in South Florida, climate maps from the United States
Geological Service indicated roughly a full third of the U.S.
is suitable habitat.
The State of Florida has been working from its end to get a
handle on these snakes. They now require a yearly registration
fee, owners must display knowledge of handling and care, and
snakes are now micro-chipped--so if one got loose you would
have a chance to chase them down. It's time for the Federal
Government to step up and address this ecological crisis.
With more than a hundred thousand of these snakes on the
loose in the Everglades we must do something before the
ecological balance is destroyed. We must change the law, and we
must do it quickly.
Finally, I would like to thank you again for taking a look
at the impact non-native plants and animals are having on our
Nation's natural resources and protected ecosystems. Florida is
ground zero for exotic plants and animals. From the Brazilian
pepper to Nile monitor lizards, we have seen it all.
I would welcome the opportunity to work with you on
reforming the way we allow species from all over the world into
the United States. There might be a way to stop the next
Burmese python from establishing a foothold here.
Senator Cardin. Well, thank you for your very powerful
testimony, Senator Nelson.
Our first panel will consist of our Federal agencies. We
have, representing the United States Fish and Wildlife Service,
the Assistant Director for Fisheries and Habitat Conservation,
Gary Frazer, and then from the United States Department of
Agriculture, Animal and Plant Health Inspection Service, Acting
Associate Administrator Bill Clay.
Mr. Frazer, we are glad to hear from you. Your full
testimony will be made part of the record. You may proceed as
you like.
STATEMENT OF GARY FRAZER, ASSISTANT DIRECTOR FOR FISHERIES AND
HABITAT CONSERVATION, U.S. FISH AND WILDLIFE SERVICE
Mr. Frazer. Thank you.
Chairman Cardin, Chairman Whitehouse and members of the
subcommittees, I am Gary Frazer. I am the Assistant Director
for Fisheries and Habitat Conservation of the U.S. Fish and
Wildlife Service. I also serve as co-chair of the Aquatic
Nuisance Species Task Force.
I am joined today by Dr. Jonathan Sleeman, Director of the
U.S. Geological Survey's National Wildlife Health Center. And
thank you for the opportunity to testify today.
Non-native invasive species have significantly affected the
health of our native species and ecosystems, and the U.S.
continues to see non-native potentially invasive species
crossing our borders through various pathways. Given the global
nature of our economy and transportation systems, we expect
this trend to continue.
Invasive species are among the primary factors that have
led to the decline of native fish and wildlife populations in
the United States and are among the most significant natural
resource management challenges facing the Fish and Wildlife
Service.
We know that about 4 in 10 species that the Service
protects under the Endangered Species Act are at risk in large
part due to the effects of invasive species. Aquatic invasive
species have harmed America's sport and commercial fisheries.
And invasive species are one of the most significant threats to
the National Wildlife Refuge System.
A September 2008 report of the Government Accountability
Office listed invasive plants as the No. 1 threat to habitats
on refuges and invasive animals as the third greatest threat.
Preventing non-native species from being introduced or
established is the most cost-effective strategy for dealing
with invasive species. Control is costly, and the conservation
community has limited tools for long-term management,
particularly of aquatic invasive species once they become
established.
Preventing the introduction and spread of non-native
invasive species requires a comprehensive approach including
Government regulatory tools, such as import screening and
injurious wildlife prohibitions, pathway management, and public
education and outreach.
Now I would like to turn to the threats of disease to
native fish and wildlife.
Human-induced changes to the landscape, including the
introduction of non-native species, climate change and
declining water and environmental quality, appear to be
contributing to a surge in infectious disease and parasites
afflicting native fish and wildlife. Some pathogens are endemic
to the United States while others are introduced and the
pathogens themselves could be classified as non-native invasive
species.
Non-native infectious diseases are of particular concern
because native wildlife populations are less likely to have
developed immunity to these pathogens. Non-native pathogens
introduced into highly mobile wildlife species can spread
rapidly, be difficult to control, and have severe ecological,
economic and even human health impacts.
An example is white-nose syndrome of bats, which was first
documented in January 2007 in hibernating bats in New York. It
has since been documented in hibernating bats in 9 States
including Virginia and West Virginia. More than 90 percent of
bats in affected caves have died, with a few caves showing
close to 100 percent mortality.
Thus far, six bat species have been affected, including the
endangered Indiana bat. The sudden and widespread mortality
associated with white-nose syndrome has never been observed
before in any of the more than 1,100 species of bats known to
science.
The Service is leading the Department of the Interior's
response to the emergence and spread of white-nose syndrome in
bats, in cooperation with the USGS, the National Park Service,
the U.S. Forest Service, State fish and wildlife agencies and
many other partner agencies and organizations. And we expect to
have management recommendations in place by September of this
year.
The Service and USGS work very closely with State fish and
wildlife agencies on surveillance, diagnosis and management of
fish and wildlife disease. The nature of State and Federal
authority over fish and wildlife requires close and
collaborative relationships and capability among all the
partners. To this end, the Service and USGS are partners with
the State fish and wildlife agencies in development of a
National Fish and Wildlife Health Initiative, an initiative of
the Association of the Fish and Wildlife Agencies.
The overarching goals of this initiative are to establish
and enhance fish and wildlife agency capability to address
health issues of free ranging fish and wildlife and to minimize
the negative impacts of health issues affecting free ranging
fish and wildlife through management, surveillance and
research. As with invasive species, preventing and controlling
disease in fish and wildlife requires capability and
coordinated effort among many parties.
Invasive species and fish and wildlife disease are existing
threats to fish and wildlife populations that will only grow in
significance in the face of changes to the physical environment
caused by climate change. Managing these existing stressors to
fish and wildlife, and anticipating how they may be exacerbated
by a changing environment, are essential elements of sustaining
our Nation's fish and wildlife in the face of climate change.
Mr. Chairman, the Service appreciates your interest in
these issues and looks forward to working with you to address
these threats to our Nation's fish and wildlife.
Thank you again for the opportunity to appear before you
today, and I would be happy to respond to any questions you or
the subcommittees may have.

Mr. Clay.
STATEMENT OF BILL CLAY, ACTING ASSOCIATE ADMINISTRATOR, ANIMAL
AND PLANT HEALTH INSPECTION SERVICE, U.S. DEPARTMENT OF
AGRICULTURE
Mr. Clay. Good morning, and thank you for the opportunity
to testify before your subcommittees.
I am Bill Clay, the Acting Associate Administrator for the
USDA Animal and Plant Health Inspection Service, or APHIS. I am
joined this morning by Dr. Jere Dick, Associate Deputy
Administrator for APHIS' Veterinary Services Program, and I
will be speaking to you about APHIS' role in relation to
wildlife diseases and invasive species.
APHIS' mission is to protect the health and value of
American agriculture and natural resources, which we primarily
accomplish under the Plant Protection Act, the Animal Health
Protection Act, and the National Animal Damage Control Act.
Wildlife are reservoirs for a number of serious diseases
such as chronic wasting disease, brucellosis, plague, rabies
and bovine tuberculosis, to name a few. Many pose a risk of
disease spread to agricultural animals, particularly as the
interaction between wildlife and livestock continues to
increase. And in several cases, wildlife can pose an elusive
reservoir for diseases that APHIS is trying to eradicate in
livestock.
APHIS, through its Veterinary Services and Wildlife
Services Programs works to address the animal disease threats
from both the wildlife and livestock interface. In addition to
protecting livestock, our agency also seeks to safeguard
wildlife resources from livestock diseases, as well as emerging
diseases and invasive species.
One example is our cooperative effort in Michigan to combat
bovine tuberculosis in both wildlife and livestock. We are a
lead agency, in cooperation with the Michigan Department of
Natural Resources and our industry partners in the Federal-
State Wildlife Risk Mitigation Program, which assists livestock
producers in preventing disease spread from wildlife to
livestock.
APHIS conducts wildlife risk assessments of livestock
facilities, develops and funds mitigation plans to increase the
separation between wildlife and livestock, and conducts bovine
tuberculosis surveillance and disease management in affected
herds, among other things.
Another example is viral hemorrhagic septicemia, which has
caused die-offs in many freshwater species in the Great Lakes.
The virus could also affect commercially raised fish in other
parts of the country. So, in cooperation with the U.S. Fish and
Wildlife Service, we issued a Federal order preventing the
movement of potentially infected fish out of the Great Lakes
watershed region to unaffected parts of the country.
Our work to address rabies has significant public health
and wildlife health impacts. We work closely with our State
partners and others to annually distribute more than 11 million
oral rabies vaccination baits to reduce the threat to humans,
domestic animals and wildlife.
We also work closely with the U.S. Centers for Disease
Control and Prevention and with Canada and Mexico as part of an
international strategy for rabies. This program is a model for
the One Health Initiative, a worldwide strategy that promotes
expanding interdisciplinary collaboration and communication and
that recognizes the critical link between human health and
animal health.
We also work cooperatively with the States to eradicate
invasive species which can devastate ecosystems. For example,
nutria, a large semi-aquatic rodent native to South America has
caused extensive damage to wetlands, agricultural crops and
structural foundations and may serve as a reservoir for
disease. We are working to eradicate nutria on the DelMarVa
peninsula in Maryland and have removed more 13,000 to date.
Also, in Florida's Grassy Key, we are working with the
State to eradicate the Gambian giant pouched rat, a rodent
native to Africa. We are in the final stages of surveillance
and removal of any remaining rats which could cause significant
agricultural damage and damage to natural resources if they
reach the mainland. We also have ongoing invasive species
programs for brown tree snakes in Guam, for coqui tree frogs in
Hawaii and for feral swine in several of the States.
Finally, research is a vitally important part of our
wildlife disease management efforts. Our National Wildlife
Research Center scientists design, develop and test new tools
for minimizing human-wildlife conflicts that are biologically
sound, environmentally safe and socially acceptable. National
Wildlife Research Center scientists investigate the ecology and
transmission of wildlife diseases, as well as develop and test
wildlife vaccines and new disease surveillance methods.
Wildlife diseases studied there include avian influenza,
bovine tuberculosis, chronic wasting disease, pseudorabies,
West Nile virus, rabies, and others.
In summary, APHIS has a deep understanding of the link
between the health of wildlife, the health of our Nation's
agricultural animals, and the impacts of invasive species. We
are committed to continuing the strong cooperative partnerships
with other Federal agencies and our State partners as we work
to protect the agricultural and natural resources of our
Nation.
We appreciate the interest of your subcommittees in these
efforts, and we look forward to working with you on wildlife
issues of mutual interest.
This concludes my testimony, and I would be happy to answer
any questions that you may have.
[The prepared statement of Mr. Clay follows:]
[GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
Senator Cardin. Thank you very much.
Senator Nelson has asked the committee to include the fact
sheets on the python incidents. Without objection, that will be
made part of the record.
[The referenced information follows:]
[GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
Senator Cardin. Let me point out to the members of the
committee that I have been informed there will be two votes
starting in a few minutes on the floor of the Senate. It is my
intention to keep the hearing in session. Senator Whitehouse
has indicated that he will be back after the first vote, in
time for me to do that. If that, in fact, carries out, we will
try to continue the hearing.
Let me start with some questions, if I might, in regards to
the eradication programs, Mr. Clay, which you are referring to.
I have seen first hand the work that has been done on the
nutria in Blackwater, and I am very impressed with the public-
private partnership. I think you said it was 13,000 or 8,000--
--
Mr. Clay. Thirteen thousand.
Senator Cardin. Thirteen thousand nutria have been removed.
That is quite an impressive effort, and I know that we have
seen the result, the effects of these results.
My question is, how effective is this program? Can we
expect that we can completely eradicate the nutria from the
Eastern Shore of the DelMarVa peninsula? Or is this a
management issue more so than effort to completely eradicate?
Mr. Clay. Well, Senator, once that invasive species becomes
firmly established, like nutria have in the DelMarVa peninsula
or in Louisiana, or as brown tree snakes have become
established in Guam, I think we have to be careful about using
the word eradicate because I am not convinced that we can
entirely eradicate every single animal.
I do think with the nutria, brown tree snakes and other
invasives that have become firmly established, we can control
the problem to the point where it is no longer, where it does
not cause any environmental effects. I am not sure that we can
entirely eradicate them, but I do think that we can make it not
the problem that it is today.
Senator Cardin. So it is more of a management issue than an
eradication issue?
Mr. Clay. Yes.
Senator Cardin. Mr. Frazer, I heard you say that our
strategy should be to try to prevent the introduction of
invasive species. We have the Lacey Act dealing with injurious
species. Do we need to look at changing that law? Is there the
right balance? As I understand it, there is more focus on
livestock-type products than there are for general control at
our borders. People can bring in pets and then release them, as
we have seen with the snakehead, as we have seen with the
python.
Do we need to look at changing that law? Is this an
enforcement issue? What do we need to do to be more effective
in dealing with injurious types of introductions into the
United States?
Mr. Frazer. Well, Senator, there are multiple authorities
to address controlling the importation of non-native species
into the United States. When it is a public health issue, CDC
has authorities. When it is an agricultural health issue, USDA
has authorities. When it is an issue related to injurious
nature to fish and wildlife, the Service has authority under
the Lacey Act to undertake rulemaking to add a species to the
list and prevent its importation and to interstate transport of
those species.
It is a rulemaking process. It is process laden and
cumbersome. The Service has not been resourced to staff that
program at a high level. And so it has taken, in many cases,
several years for us to move through the process of adding a
single species to the list.
It is also been administrated in a fashion that is more
reactive in the past. Species that already have been imported
and demonstrated to be of concern in the U.S. or those that
have tended to be the focus of adding them to the list.
So, I do think that we need to be looking both
administratively to improve the process and do what we can, in
terms of adding more resources, doing everything we can to
improve the administrative process of getting through the
rulemaking, and we should also be looking at other approaches
that will be more proactive in nature.
Senator Cardin. We would look forward to your
recommendations there. I mean, I think Senator Nelson makes a
very strong point about the Burmese python, that even if it
were added to the list, the damage has been done. The question
is, can we stay ahead of the curve?
Are there certain types of animals that should not be
permitted in this country because of its tendency to be a pet
for a short period of time and then released to the wild that
could cause damage here in America? I think that is an issue
that we should try to stay ahead of the game, rather than just
trying to be reactive, as you said. I am not sure what the
answer is, but we certainly welcome your thoughts as to giving
you additional tools to deal with that.
Mr. Frazer. We would be happy to work with you. I testified
recently before the House Natural Resources Committee on a bill
that has been introduced on the House side that took a
different approach. So, we would be happy to explore options
with you.
Senator Cardin. And what was that approach?
Mr. Frazer. It was one that established two different
lists, an approved list and an unapproved list. It recognizes
some species that might fall in the middle, and you have to do
a case-by-case approach. It was one that sought to provide a
more proactive approach, provide more certainty to importers.
It placed the onus upon importers to provide information upon
which to make the risk assessment. It was designed to be more
timely, more proactive. There are a number of issues that are
associated with making such a thing work, not the least being
the resources that would be involved.
Senator Cardin. I think Senator Barrasso raises a very
valid point about industries in America depending upon
diversity in species, which is certainly something that we do
not want to stop. But there are certain types of wildlife that
really does not serve that purpose, that the potential danger
seems to me outweighs any of the benefits, including it being
an exotic pet. And we would hope you have the authority to move
more rapidly to prevent a Burmese python circumstance in the
future.
Senator Barrasso.
Senator Barrasso. Thank you very much, Mr. Chairman. And
thank you for that reference. I do have letters from the
Chamber of Commerce of the United States and the Retail Leaders
Association. I would like to introduce those----
Senator Cardin. Without objection, it will be included in
the record.
Senator Barrasso. Thank you, Mr. Chairman.

Senator Barrasso. Mr. Clay, my impression has been that the
USDA has broad authority in controlling injurious wildlife
species in terms of entering into agreements with States, with
local jurisdictions, with individuals to control these invasive
species. How can we use the existing authorities, which the
USDA already has and the Fish and Wildlife Service has, to
address some of these threats to our native species? Are there
things we can do right now with the laws already in place?
Mr. Clay. Well, I think, as far as the APHIS wildlife
services program, we are not a regulatory program, unlike the
other programs in APHIS. So, we would work strictly on a
request basis from State or Federal agency or the private
sector. As far as the regulatory authorities in APHIS regarding
livestock health, I think there are appropriate authorities
that cover veterinary services activities there.
So, we will be glad to assist any State or Federal entity
that requests our assistance if it falls under the regulatory
authority.
Senator Barrasso. Following up with Mr. Frazer, I look at
the Game and Fish Department in Wyoming. It is very concerned
about some of these aquatic invasive species that we talked
about, that Senator Levin talked about beginning in the Great
Lakes, and we have concerns.
What can the U.S. Fish and Wildlife do to support a State
effort to tackle this threat, short of adopting some sweeping
new Federal law which I know my State is not really asking for?
They are just asking for some help.
Mr. Frazer. Well, as I said, I co-chair the Aquatic
Nuisance Task Force, which is organized to coordinate Federal
efforts to address aquatic nuisance species but also is closely
connected with six different regional panels that reach out to
State agencies.
Through that effort, the Fish and Wildlife Service led what
we called the Hundredth Meridian Initiative, which, through the
1990s, served to try to prevent the movement of zebra and
quagga mussels from the Great Lakes into the Western States.
For a number of years, it was successful. But that barrier was
breached and, as you know, zebra and quagga mussels are now
established in the Colorado River.
But we are still working closely with our States, including
through the limited dollars that we have, to provide support,
financial support, to State invasive species programs, to mount
effective prevention and control programs, to contain the
species where it is now, to do extensive public education and
outreach, because much of the movement is through recreational
boating and other pathways, and otherwise to provide leadership
and support to the States and others that have to be part of a
solution dealing with prevention and containment.
Senator Barrasso. Can I ask, also, have you done an
economic analysis? I mean, I introduced a letter from the
Chamber of Commerce about some of the impact that a broad piece
of legislation would have on things like sport fishing if you
really go ahead and adopt a precautionary approach, as opposed
to a risk-based approach.
Mr. Frazer. We have not done them in a generic fashion. But
part of the challenge of us moving through an individual
injurious wildlife determination is that we do need to do an
economic analysis and look at the effects of any prohibition on
importation on small businesses, small organizations. Those are
the sorts of additional analyses that require time and
resources and make the process challenging.
Senator Barrasso. Mr. Chairman, I know they are calling for
the vote. If I may just introduce a couple of other questions
in written form so that Senator Lautenberg has an opportunity
to ask questions.
Senator Cardin. Certainly.
Senator Barrasso. Thank you very much. I appreciate that.
Senator Cardin. Senator Lautenberg.
Senator Lautenberg. Thanks, Mr. Chairman. And thank each of
you for your very depressing testimony.
This has been a difficult hearing because we are facing up
to a problem that exists all around us, and one that has not
received the right kind of attention, in my view. When I think
about recreational boaters and what they might carry, what does
one do about that? I mean, are we out saying that you have to
wash down your boat with a particular kind of material, and so
forth, and I just cannot imagine getting people that alarmed
about it. That question does not deserve an answer. It is just
a rhetorical question.
Mr. Frazer, I have asked Interior to devote more resources
to curbing the white-nose syndrome. Now, is this situation
considered among the more serious in terms of the bat
population? Is this recognized as an imminent and massive
danger?
Mr. Frazer. We consider this a crisis in bat conservation,
particularly in the Eastern United States, and we are
redirecting existing dollars to tackle that now to the extent
that we can.
Senator Lautenberg. So, is there a provision in the
structure that enables you to move funds to the more critical
situations? Are there enough funds, as we listen to the
testimony and our colleagues have presented, are there enough
funds in reserve that are available to get out and start
fighting these situations where there are invasive species or,
in this case, a virus or whatever it is that is killing these
bats?
Mr. Frazer. We are directing funds under the Endangered
Species Act Recovery Program, as well as within our
Environmental Contaminants Program, to tackle this. USGS is
directing their discretionary research dollars to this. And a
number of other agencies are also directing, to the extent that
they have discretion, resources to tackle this issue. I cannot
speak to whether that is viewed as adequate. Now, we are all
Federal bureaucrats, so we could always do more. But there is a
significant effort mounted.
Senator Lautenberg. Thank you. Scientific studies suggest
that humans may play a role in the spread of white-nose
syndrome. The Fish and Wildlife Service has called for a
voluntary moratorium on caving in affected areas.
Now, since most of this depends on State supervision, what
does the Federal Government do to monitor what State activities
are taking place to do their part since this is not typically a
Federal jurisdiction?
Mr. Frazer. As I said in my testimony, management of fish
and wildlife disease requires a very close and collaborative
partnership with State fish and wildlife agencies. They have
the authority and responsibility, as well as the field
presence, to deal with wildlife disease that exceeds most
Federal agencies. The Federal Government can provide
leadership, it can provide financial support, it can provide
research, but in many cases it is the State agencies that are
going to be involved in the operational management activities--
--
Senator Lautenberg. But what happens, Mr. Frazer, if it is
observed that a particular State is not doing quite what they
should? Is there a corrective action that can be taken by the
Federal Government that says, hey, it is going to get you
involved with us in funding or something like that?
Mr. Frazer. We have not experienced that situation. But if
we did, at least the Fish and Wildlife Service does not have
the kind of authority to step in and federalize management of a
disease issue affecting a resident fish and wildlife
population.
Senator Lautenberg. Not to manage it, but rather to report
on it in some manner or form so that we look at whether or not
we have to make adjustments and, considering the threats that
these conditions pose, we would like to stress as much action
as we can possibly muster. Is it possible the white-nose
syndrome will result in serious direct human health impacts if
it continues to spread?
Mr. Frazer. We do not know of human health impacts
associated with this disease. Certainly, ecological impacts to
bats, a potentially catastrophic affect to bats.
I would say, with regard to our relationships with States,
it is a very close and very positive relationship, and I would
not anticipate a situation where we would be at loggerheads.
Senator Lautenberg. OK. Thanks, Mr. Chairman.
Senator Cardin. Thank you. As you pointed out, you have a
great deal of authority under different sections. I am trying
to understand when you consider it urgent to act quickly. I
know you have emergency powers to protect the public health of
the people of this Nation.
What standards are used in order to take emergency
precautions where there is an immediate threat? And is there
anything that we can learn from that that could help us,
perhaps, deal with some of these other problems in trying to
streamline the process for making decisions on border issues?
Mr. Frazer. The Fish and Wildlife Service does not have
authority to an emergency listing under the Lacey Act. We are
governed by the Administrative Procedures Act. So, the standard
there would be, basically it is a due cause standard that we
have to establish in order to take emergency action under the
Administrative Procedures Act. We do not have authority like
under the Endangered Species Act to just simply do an emergency
listing.
Senator Cardin. But you do have, USDA does have certain
emergency powers. Maybe I can try to get Mr. Clay involved
here.
Mr. Clay. Yes, sir. Senator, the Animal Health Protection
Act does give APHIS broad authority to deal with any type of
animal that poses a risk to livestock or to agriculture,
whether it is a pet or any kind of animal. If there is a risk
specifically to agriculture and it can impact agriculture,
APHIS has the authority to go in and deal with that.
Senator Cardin. But it does not extend to the situation
such as the python or the invasive nutria. If there are
snakehead, you could not list prohibited imports because of the
fear it would have on agricultural products in the country, or
could you?
Mr. Clay. We could if there was a threat from the animal.
Like, for instance, hedgehogs are prohibited from entering the
country because of the threat of tuberculosis or foot and mouth
disease from them. So, they are an animal that would be
regulated as far as watching closely. Other animals, if they do
not pose a disease threat to livestock of agriculture, would
not fall under the regulatory authority of APHIS.
Senator Cardin. It seems that is a pretty narrow area where
you can act. It is hard to anticipate that an exotic pet, which
could pose a threat to livestock, or a plant to agriculture,
would be prohibited from being introduced into America because
of the fear that it would be released into the environment.
Mr. Clay. There have been several species of tortoises that
have been prohibited because of the ticks and other arthropods
that they carry on them that are vectors of livestock diseases.
So, it really depends on the type of animal and the country it
is coming from, if there is foreign animal diseases, foot and
mouth disease or high path avian influenza or whatever, coming
from that country. That is when there would be specific
restrictions or import regulations.
Senator Cardin. And when you have taken this action, how
effective is the border control and enforcement?
Mr. Clay. Well, we work closely at all the ports of entry
with the Fish and Wildlife Service and the other Federal
partners on this. We all have different authorities that we
operate under, some of them impact wildlife or affect wildlife
and others do not. But we have been working with these Federal
partners for years. We have had long standing cooperative
relationships with them, so we understand their authorities,
their expertise, and I believe we are working very closely with
them at the ports of entry.
Senator Cardin. But there are certain prohibited items and
of course we all know what happens at the borders. Is this
generally monitoring commercial activity at our borders more so
than the individual who is returning to our country?
Mr. Clay. Well, it is looking at, primarily, wildlife or
agricultural animals coming in or their products that are
coming in that could pose a threat to the livestock or
agricultural health.
Mr. Frazer. For the Fish and Wildlife Service, Senator,
there are designated ports of entry for legal commerce and
wildlife. We permit and license importers of wildlife. They are
required to file declarations that describe what and where
their products come from. So, legal commerce is something that
comes through those designated ports, and it is in the form of
commercial activity. There are certainly illegal and
unauthorized imports of wildlife and wildlife products that
come into the country.
Senator Cardin. I will just make one final observation, and
that is that some of this could be better education, to let the
public understand the dangers of these types of releases. I
think that publicizing what has happened in Florida, for
example, the loss of life as the result of someone innocently,
they thought, releasing a snake into the wild. I think we could
do a better job. That is something that I think all of us need
to take a look at to see what we can let people know----
Mr. Frazer. Public education is, excuse me, the effective
educating and really changing the perspective of the public on
invasive species is extremely important. Senator Lautenberg
talked about washing boats or modifying the behavior of
recreational boaters. We have a specific campaign to do that,
and it has been very effective.
With regard to invasive species, particularly pet species,
we have something called Habitattitude that seeks to educate
pet owners about the dangers and risks of releasing their pets
or aquatic plants into the wild. So those are effective parts
of our strategy.
Senator Cardin. Well, let me thank both of you, and we look
forward to working with you as we try to improve our tools to
deal with this problem through our Federal regulators.
Before calling the next panel, we are going to take a very
brief recess. I expect that Senator Whitehouse will be
returning shortly which will reconvene the second panel. And as
soon as I have a chance to cast my votes, I will be returning.
[Recess.]
Senator Whitehouse [presiding]. I call the hearing to order
and start getting under way. The other members of the committee
will come back from the vote as they have concluded their
business. I gather they are back-to-back votes, so they will be
able to vote twice and then come on back.
In the meantime, Chairman Cardin has asked that we continue
the hearing, and I am delighted to welcome the witnesses who
are here today.
I gather that Director Humphries has already been somewhat
introduced by her Senator, Carl Levin. We are so pleased with
Senator Levin's and Senator Stabenow's contributions to the
Senate. I have to say you come very well represented here, and
I am very pleased to have you here as Michigan's Director of
the Department of Natural Resources.
We are also joined by Dr. Gregory Ruiz, who is a Senior
Scientist at the Smithsonian Environmental Research Center,
Marine Invasions Research Laboratory. The Smithsonian
Environmental Research Center is a global leader for research
focused on the connections between terrestrial and aquatic
ecosystems. Dr. Ruiz leads SERC's Marine Invasions Laboratory,
a national-international center for research on biological
invasions in coastal marine ecosystems.
I want to tell Dr. Ruiz that I am married to a marine
biologist who specializes in estuary science, and during the
course of my pursuit of her, I was actually dragged into her
sampling, some of which took place underwater in Narragansett
Bay in February. I guess with that I impressed her enough that
we have now ended up man and wife, or, in her case, probably
woman and husband.
I am very pleased to have you here with us to bring the
marine and coastal side of this. I think it is extremely
significant.
Also to a degree emphasizing the marine and coastal side of
this is my friend, John Torgan, from Rhode Island, who is the
Baykeeper of Narragansett Bay and works for our really primary
environmental organization of Rhode Island, Save the Bay. John
has been connected to the Narragansett Bay watershed his entire
life. His Baykeeper Program is part of the National Waterkeeper
Alliance, specialists with a passion for defending the
environment and a devotion to working among communities.
As our Baykeeper, Mr. Torgan is responsible for monitoring
invasive species in the bay and collaborating with Federal,
State and local agencies to help prevent the introduction and
spread of invasive species. Narragansett's native scallop,
river herring, Atlantic salmon, rainbow smelt, sturgeon and
American shad populations are all impacted by invasive species.
Finally, we are joined by Dr. Jeffrey Hill, who is an
Assistant Professor with the Department of Fisheries and
Aquatic Sciences at the University of Florida.
We welcome all of the witnesses, and why do we not go
across the board beginning with Dr. Ruiz.
STATEMENT OF GREGORY RUIZ, SENIOR SCIENTIST, SMITHSONIAN
ENVIRONMENTAL RESEARCH CENTER, MARINE INVASIONS RESEARCH
LABORATORY
Mr. Ruiz. Thank you, Mr. Chairman. Good morning and thank
you for the opportunity to be here today.
My name is Greg Ruiz. I am a Senior Scientist at the
Smithsonian Environmental Research Center or SERC, located on
the Chesapeake Bay. SERC is a leading national center of
research on non-native species invasions in coastal marine
systems. A primary goal of SERC's invasion research is to
advance fundamental science to understand patterns and
mechanisms of coastal invasions.
Today, I would like to highlight the current state of
knowledge about invasions in marine ecosystems, considering
Chesapeake Bay and Nation more broadly. I also wish to
underscore the need for vector management to reduce the risk
and impacts of invasions.
Invasions are rapidly changing the earth's ecosystems,
having dramatic effects on ecological processes, critical
habitats, commercial fisheries and disease outbreaks. The cost
of invasions to society is enormous, estimated in excess of
$100 billion a year in the United States alone. Invasions
result in the loss of crops and fisheries, damage to
infrastructure and water supplies, and effects on human health.
Coastal bays and estuaries are especially vulnerable to
invasion by non-native species. This is exemplified by
Chesapeake Bay, the Nation's largest estuary. SERC's research
has documented over 177 non-native species with established
populations in Chesapeake tidal waters. The rate of documented
invasions here has increased dramatically over the last
century. These organisms were delivered from around the globe
by a diverse range of human activities.
Some invasions have large effects on the Chesapeake Bay
region. For example, the oyster parasite MSX, from Asia, causes
mass mortality of the native Eastern oyster, contributing to
the collapse of Chesapeake's iconic fishery and undermining
efforts for recovery.
As Senator Cardin indicated, the nutria, a South American
mammal, is responsible for destruction of salt marsh habitat,
converting marsh to bare mud and removing critical habitat for
waterfowl, fish and other organisms.
Also of great concern is the observed increase in new
invasions for the Chesapeake. On a daily basis, non-native
species are delivered to our shores by many different human
activities, including the movement of ships, recreational
vessels and live trade organisms such as seafood, bait,
aquarium pets and aquatic plants. As a result, new invasions
continue to occur, such as the mitten crab, which has been
found now from Chesapeake up to New York.
The Chesapeake serves as a model for what is occurring with
invasions across the Nation. As Senator Nelson indicated today,
invasions pose a significant challenge for resource management
and undermine restoration efforts. This situation is
exacerbated by the growing number of invasions and also the
effects of climate change. Increasing temperatures expand the
number of species that can colonize by creating suitable
conditions for survival and reproduction that did not
previously exist.
There are two key steps that are needed to address invasion
impacts. The first is to reduce the risks of future invasions
by new species. The second is to eradicate or control selected
high impact species that are already established. However,
unless we address the increasing number of new invaders, our
capacity to mitigate established evasions is rapidly
overwhelmed.
One obvious priority for the Nation is vector management.
Rather than a species-by-species approach, vector management
seeks to disrupt the shared transfer process of many species at
once. I describe this in more detail in my written testimony.
There is still considerable work to be done to achieve
effective vector management. The Nation's current approach is a
patchwork applied inconsistently across different transfer
mechanisms or vectors.
There are also critical scientific gaps that limit vector
management. One of these is tracking and measuring the
occurrence of invasions over time. This is key to identifying
the source of new invasions for response. This is also needed
to assess the long-term effectiveness of vector disruption.
Remarkably, there exists no national program to provide the
type of standardized measures needed to assess the status and
trends of coastal invasions in America today. This presents
significant problems for vector management. Many regions,
habitats and taxonomic groups have not been surveyed in recent
years or even decades, providing only a party picture of
invasion dynamics.
Piecing together data from existing programs is
insufficient because they have conspicuous gaps. To reduce
invasion risks and impacts, we need a consistent approach to
vector management. This requires the use of standardized
quantitative surveys to track invasions. Without such field
measures, we are often left guessing about the status, trends
and emerging threats of invasions, limiting effective
responses.
In my written testimony, I have outlined some possible
approaches to meet this challenge.
Thank you very much.

Director Humphries.
STATEMENT OF REBECCA HUMPHRIES, DIRECTOR, MICHIGAN DEPARTMENT
OF NATURAL RESOURCES
Ms. Humphries. Thank you, Mr. Chairman.
I am Becky Humphries, Director of the Michigan Department
of Natural Resources, and I am also the Chair of the Fish and
Wildlife Health Committee of the Association of Fish and
Wildlife Agencies.
I appreciate the opportunity to share with you today the
perspectives of State fish and wildlife agencies on the vital
issue of emerging fish and wildlife disease.
All 50 States are members of the Association of Fish and
Wildlife Agencies. The Association strives to enhance and
facilitate cooperation and coordination among State, Federal
and tribal agencies with respect to fish and wildlife
conservation.
Today, I will share with you the Association's approach to
this challenge through the development and implementation of
the National Fish and Wildlife Health Initiative. I will
characterize the national approach to managing chronic wasting
disease, CWD, through the development of a State, Federal and
national plan which I think was a good model. I will also
briefly reflect on my experiences in Michigan, our lessons
learned with several of these diseases, including bovine
tuberculosis, chronic wasting disease, and viral hemorrhagic
septicemia.
State fish and wildlife agencies have the statutory, and
often constitutional, responsibility for the conservation of
fish and wildlife within their borders for the benefits of
their citizens. The Association of Fish and Wildlife Agencies
developed the National Fish and Wildlife Initiative to create a
system for coordination between State, Federal, tribal and
private industry to ensure the early detection of pathogens and
the appropriation response and management of these diseases.
The two overarching goals of the initiative are first, as
you have heard, to assist States and Federal agencies in
enhancing their capacity and appropriately addressing fish and
wildlife health issues. And second, to facilitate close
cooperation between State and Federal fish and wildlife, animal
health and human health agencies with respect to fish and
wildlife pathogens and diseases in order to minimize their
negative effects.
The initiative is a policy framework by which all
interested parties may seek both to minimize the negative
impacts of disease agents in fish and wildlife and to
proactively promote healthy fish and wildlife populations. A
copy of the initiative is appended to my statement for your
reference. It is interesting to note that we have three of the
Steering Committee members here today testifying.
The growing importance of fish and wildlife health issues
in natural resource management is dramatic. It makes it
imperative that more resources be directed toward them in the
future. Building capacity at all levels of government for early
detection and the execution of coordinated response plans
provides the best known strategy for successfully dealing with
disease incidents.
State and Federal coordinated disease response planning is
a model that has been successfully practiced in recent years.
In 2002, the U.S. Department of Agriculture and the U.S.
Department of Interior convened a taskforce to coordinate CWD
management, which included both Federal interests and
eventually State interests as well. The work of the taskforce
culminated in the development of a national plan that guides
surveillance and management actions.
Congress followed up by appropriating over $10 million for
CWD management, part of which has been made available to the
States for use in surveillance and monitoring. In Michigan, we
used the national plan and the funding made available through
USDA APHIS to specifically plan for and prepare a response to
the potential detection of CWD in Michigan.
In the fall of 2008, in the late summer, we found CWD in
Michigan. Over a period of 2 years, funds made available
through USDA APHIS accounted for testing of nearly 12 percent
of all cervids tested in Michigan for CWD so far. By
coordinating Federal efforts and funding within State specific
planning efforts, State fish and wildlife agencies have been
better positioned to characterize the distribution and
intensity of CWD and evaluate the risks.
These Federal funds and the flexibility of cooperative
agreements between States like Michigan and the Federal
Government have made it possible to conduct large scale
wildlife disease surveillance, in some States for the very
first time, which certainly could not have occurred without
this coordinated effort.
Through our experiences with bovine TB and VHS, Michigan
has learned another important lesson. Fish and wildlife disease
management is not restricted to the identification of vectors,
the isolation of infected individuals, and the removal from the
population. Fish and wildlife bring significant economic and
cultural interests to bear upon management strategies, and
those interests bring political attention as well.
These juxtaposed interests have required a new paradigm in
disease mitigation. Because diseases like bovine TB and VHS can
be vectored through the action of hunting and angling
communities, it has become essential to plan and provide for
inclusion and partnership with the public.
The new cultural norm where traditions have been altered to
conform to the new demands of disease on the landscape have
been partially achieved, but not without concerted and
consistent effort in the face of, at times, an unwilling
public. Planning for cultural, social and political
consequences of a disease incident should be viewed as
essential.
Through our experiences with CWD, bovine TB and other
diseases, we believe adequate authorities already exist.
However, we need to put more resources into our work so that we
can adequately expand our capacity and capabilities to respond
to what we expect to be an increasing number of diseases.
We have also learned that disease planning efforts need to
include the public and have their involvement and engagement.
Thank you for the opportunity to share the Association's
perspectives and I would be happy to address any questions.

Senator Whitehouse. Thank you very much, Director. I
appreciate your bringing your views.
Next is Baykeeper Torgan.
STATEMENT OF JOHN TORGAN, NARRAGANSETT BAYKEEPER, SAVE THE BAY,
INC.
Mr. Torgan. Thank you, Mr. Chairman. It is really an honor
to be here.
The problem of invasive species poses serious economic and
environmental risks to rivers, bays and coastal systems
nationally. According to recent estimates, the United States
spends in excess of $138 billion annually on control measures.
While this problem itself is not new, changing
environmental factors and new species introductions have
contributed to dramatic shifts in the types of plants and
animals we see in our region and across the country and have
opened the door for non-native species to take hold.
In Narragansett Bay and Southern New England, we have
observed fundamental changes in the fish and shellfish
populations as water temperatures have warmed over the past 30
years.
The extent of low-oxygen dead zones on the bottom has
spread as warmer water and pollution contribute to massive
algae blooms. The populations of classic cold water New England
fish and shellfish species, like lobster, cod, winter flounder,
river herring and scallops, are all down as jellyfish, algae,
and other warm water-tolerant fish like striped bass and
menhaden have recently increased.
You mentioned Dr. Whitehouse's dissertation work on winter
flounder. That is very much on point here. That looked at a
kind of shrimp that used to be excluded in cold winters in
Narragansett Bay, but in warmer winters it can now get in,
called the crangonshrimp or seven spine shrimp, and eat the
baby winter flounder. So, this is an example of, not an
invasive species, but a changing condition that opens the door
to more problems from invasions.
Invasive plants and animals thrive under these warmer
conditions. They are causing some negative, but mostly unknown,
impacts on the broader coastal ecosystem. Asian shore crabs,
which we first observed in the mid-1990s, are now the most
common species of crab, the most prolific in front of our main
offices in Providence. You cannot turn over a rock there
without finding one. We do not know if they have driven out the
native crabs or what the extent of the damage is yet, but that
is something that we need to study.
Certain shellfish diseases like dermo, MSX and juvenile
oyster disease, once much more common in Mid-Atlantic waters,
have nearly wiped out our native oyster populations. Lobster
diseases further weaken an already struggling industry in
Southern New England. Commercial fisheries and the historic
seafood industry of the region are facing unprecedented
challenges from these and other changes.
The same changes can be observed in avian, other fish
populations, mosquitoes with West Nile, and EEE, these may also
be related to temperature.
Understanding biological invasions requires knowledge of
past and present populations. We are only just beginning to get
a clear picture of what is in our ecosystem today. Doing
comprehensive baseline assessments in States helps us
understand what is really new and what has been there and what
is a threat.
Rhode Island has just established a citizen-based
environmental monitoring program for aquatic invasive species
which is an interagency and university effort. We participate
in that.
The National Invasive Species Act has enabled all of this
progress to date. Since its passage, Congress has appropriated
$1.7 million per year for States to develop invasive species
management plans. Individual States' shares of that money have
been declining though as more States receive approval for their
plans from the Federal Aquatic Nuisance Species Task Force.
Rhode Island's share, for example, dropped from $45,000 to
$35,00 in the past year. So, it would help States a great deal
if Congress were to appropriate the additional $3 million
authorized in that Act.
While my organization is focused primarily on coastal
waters and estuaries, invasive species on land affect our
environment significantly, especially where land and water
interface. I will use the example of phragmites, the giant reed
grass. I took the train from Providence, and you can see vast
acres of it as you go through coastal Rhode Island,
Connecticut, New York, New Jersey, all the way down here. We
have an invasive species, phragmites, which takes over and
transforms wetlands into a monoculture.
But we have identified some feasible control measures for
it. Habitat restoration, allowing tidal water and salt water
from the tide, where that is feasible, can knock out
phragmites. Where that is not possible with some of the other
aquatic plants species, you can treat them using a combination
of approved herbicides, cutting and treating over the course of
several seasons. But that is expensive and is labor intensive.
Forests, as some of the other witnesses have pointed out,
are also at risk with things like the Asian longhorn beetle. By
managing those, by clearing forests, that has an impact on
water quality through increased runoff.
We know that prevention, as Senator Cardin had said
earlier, is the best and most cost-effective control measure.
But investing in screening and other controls at ports,
airports and other points of entry would help. Once they are
established, it is very difficult to get them out.
Another important role for non-profit organizations like
mine is in education, in public communication and in outreach,
to directly involve people in understanding the problem and the
solution.
Finally, we believe that regional management is the most
effective approach to these issues and this approach needs to
engage multiple States because the species do not respect
borders. In New England, the Northeast Aquatic Nuisance Species
Panel of the Federal Task Force helps to coordinate regional
efforts and maintain frequent communications with the public.
We view this as an effective model.
Thank you for this opportunity to testify. I would be happy
to answer any questions.

Senator Whitehouse. Thank you very much, John, and once
again, welcome. It is wonderful to see you here.
Our last witness is Professor Jeffrey Hill from the
University of Florida.
STATEMENT OF JEFFREY E. HILL, ASSISTANT PROFESSOR, DEPARTMENT
OF FISHERIES AND AQUATIC SCIENCES, UNIVERSITY OF FLORIDA
Mr. Hill. Mr. Chairman, thank you for the opportunity to
testify concerning the threats of invasive species to native
wildlife.
I am Dr. Jeffrey Hill, Assistant Professor of Fisheries and
Aquatic Sciences at the University of Florida. My teaching,
research and extension programs involve ecology and management
of non-native aquatic species. I teach a course in invasion
ecology, conduct field laboratory research, and apply
ecological theory and practical experience to risk analysis. I
have conducted and reviewed risk analysis efforts for sports
fish, aquaculture species and ornamental species at State,
Federal and international levels.
I am the President-Elect of the Introduced Fish Section of
the American Fisheries Society and a member of State and
national non-native species scientific advisory committees,
including the Research Committee and the Detection and
Monitoring Committee of the Aquatic Nuisance Species Task
Force.
Invasive species threaten native species and ecosystems,
economic values and human health in every State and U.S.
Territory. Invasive species arrive in the United States through
a variety of pathways, including intentional importation and
interstate trade, as well as via unintentional pathways such as
ballast water.
The negative effects of many invasive species, such as
zebra mussels and brown tree snakes, as well as wildlife
diseases such as VHS, are well known. I will not discuss them
further, except to say that some invasive species are
ecologically devastating or economically important and costly
pests.
Few would argue that invasive species are not a problem in
the United States. It is imperative for Federal and State
agencies to provide effective, reasonable regulation of
pathways and problematic species to reduce the frequency and
negative effects of species invasions.
Invasive species or a small subset of non-native species,
specifically non-natives that threaten ecological or economic
harm, or human health. All invasive species must go through a
series of steps to become invasive. They must be introduced
into the environment, established, spread and then some will
become invasive.
Although these steps sound simple, you may be surprised to
learn that the process is fraught with difficulty and that most
introductions fail. Literally millions of individual animals
and thousands of species are moved across State lines or
imported annually. Some of these get introduced into the
environment. Of these introductions, only a small percentage
make it to the establishment or spread phase, and only a few
established species have important negative effects.
The primary Federal regulatory tool for non-native species
is the Lacey Act. Unfortunately, this system, as currently
implemented, is not as effective as it should be. An effective
system needs to focus limited resources on problematic species,
address gaps in authority, for example diseases that primarily
impact wildlife, be timely reducing listing time to months
rather than years, be open, transparent and stakeholder
inclusive, use science-based credible risk analysis, allow for
a regional approach to managing risk, be centralized and
adequately supported with resources.
These recommendations could be accommodated within the
current system. Invasive species prevention and management
hinges on risk. Risk is a function of the probability of an
event occurring and the consequences if the event occurs. Risk
analysis is a complex scientific and sociological exercise that
seeks to identify risks, estimate their magnitude and reduce
risks to acceptable levels.
Risk assessment should be transparent, repeatable,
scientifically credible and defensible. It must also be
acknowledged that there is scientific uncertainty in all
methods. Risk assessments are expensive and time consuming,
usually requiring months to complete. Data needs for assessing
risks are considerable. Data is lacking for many species, and
most current data bases are inadequate for the task.
Risk management can seldom reduce risks to zero. Non-zero
levels of risk must be considered for any use of non-native
species. Decisions on acceptable risk levels should be based on
scientific information, on probable, not possible effects,
cost-benefit analysis, conservation analysis and cultural
factors.
It would be a Herculean task to assist thousands of species
with hundreds of interest groups with these species. It is my
expert opinion, based on having done risk analysis, that it is
impractical to conduct thorough, defensible risk analysis of
thousands of species in a timely manner given any reasonable
level of research allocation.
The focus should be on highly problematic species. States
have broad authority to manage fish and wildlife resources and
have considerable experience and expertise related to the
regional nature of pathways, ecosystems and risk.
Important roles for the Federal Government would be to
coordinate the efforts of State, especially States with common
pathways and ecosystems, facilitate State-based programs,
bridge important gaps where States lack sufficient authority,
and help resolve differences between States.
Working with States would provide a mechanism for reducing
risk on a regional basis. The Federal Government could
considerably leverage resources by sharing the burden of risk
analysis, regulation and enforcement with States.
In conclusion, my recommendations are to thoroughly revisit
the Lacey Act with extensive input from scientific experts and
interested stakeholders, provide substantially increased
resources of staff and funding to the Fish and Wildlife
Service, use appropriate screening methods followed by risk
analysis if needed for any non-native species newly proposed
for importation, and begin a risk based process for those
species currently in trade that are identified as problematic
or likely to become problematic.
Many of these recommendations are already contained in the
National Invasive Species Management Plan developed by the
National Invasive Species Counsel.
Thank you for the opportunity to present my views. I look
forward to working with you on these issues.
[The prepared statement of Mr. Hill follows:]
[GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
Senator Cardin [presiding]. Let me thank all of our
witnesses for their testimony, their contribution to this
hearing.
Dr. Ruiz, first I want to welcome you to the panel. As a
person who lives in Maryland, we are very honored that you are
here with us and the work that you do. I thank all of the
members of the panel, but I have to certainly acknowledge my
Marylander who is on the panel.
I want to talk about the Chesapeake Bay for a moment. As
you point out, there is over a hundred invasive species in the
Chesapeake Bay. I do not know if that is the Chinese mitten
crab that you have there or not. Is that what you have in front
of you?
Mr. Ruiz. Yes, it is a Chinese mitten crab that has been
showing up in the Chesapeake Bay and to the north.
Senator Cardin. That has me greatly concerned. The crab
industry is synonymous with Maryland and the Chesapeake Bay,
and particularly in the month of July we all very much think
about our delicacy that we have given to the world. What danger
do we have that this crab could become a significant part of
the population and effect the blue crab, the Maryland blue
crab? Is this a risk factor that we do not know about yet?
I ask that because one of the questions, one of the points,
that all of you have been raising, is do a risk assessment
early so you do not have to try to clean up the mess later,
which becomes much more difficult.
Mr. Ruiz. I think the mitten crab is a concern. It
underscores exactly the point that you are making, I think, and
also that Professor Hill made, that there is a lot of
uncertainty about what will happen when a non-native species
shows up in one of our ecosystems like the Chesapeake Bay and
that it is a species that transported from one part of the
world and moved to another one with a different community, a
different suite of organisms. And so, we really have a very
poor understanding of how it is going to interact and what will
play out.
The mitten crab is of concern because it is a species that
goes through massive outbreaks, kind of like cicadas do
seasonally here, but on a much longer time scale. There was an
outbreak that occurred in San Francisco Bay that damaged some
of the water supply system in the San Francisco delta.
In the Chesapeake region, I do not think we really know
what the impact is going to be of this crab if it is
established, what effect it might have on infrastructure, water
supply in particular, and how it might interact with the blue
crab in terms of competition for resources or even as a
predator on juvenile blue crab that it may interact with as it
moves down into salt water.
Senator Cardin. We already have a problem with the survival
of juvenile crabs, the blue crabs. The protective grasses are
being affected by pollution and global climate change. So we
already are finding it a challenge to preserve the food stock
basically for the mature crabs. In some cases, they eat their
own. And now, if the Chinese mitten crab is going to be
competing with that, if could complicate the survival of the
blue crab in Maryland.
Mr. Ruiz. I think that is exactly right. As we are
struggling to recover the commercial fishery and the blue crab
population in Chesapeake, the arrival of new non-native species
is one more stressor, one more factor, which makes it even more
challenging to recover a fishery like the blue crab.
We do not, of course, know what the impact of Mitten crabs
will likely be if it is established and becomes abundant. It is
a point of concern, and it is something that I think we need to
take very seriously.
Senator Cardin. Do we know how this was introduced into the
Bay?
Mr. Ruiz. The mitten crab is also an interesting example in
that it underscores some of the uncertainty there. There are
two likely ways in which it could have come. One is through the
ballast water of ships. What we know from specimens that we
have collected so far is that the genetics tell us it is likely
coming from Europe where the mitten crab is also established.
It has been there for over 100 years now. So, it could have
well come from ships delivering ballast into the Chesapeake or
the Mid-Atlantic region.
The other possibility is that it could have come as live
trade in that it is a commercially important crab, particularly
in Asia. It is also eaten in Europe. So it is possible that
someone brought it in. It is illegal to do that now under the
Lacey Act. Whether it could have been brought in when it was
still legal, or whether it could have been brought in
illegally, we do not know.
So, there is some uncertainty. But those are the two
pathways or mechanisms by which it could have arrived.
Senator Cardin. And, of course, the related issue is that
there is an intentional introduction of an invasive species,
the Asian oyster, and it certainly has its controversy when we
intentionally introduce a new species into the Bay. That is
being done because of the real concern of the loss of oysters,
which are not only a commercial crop but are a filtering agent
for clean water. I know there is a lot of work being done to
monitor the Asian oyster. Are there adequate resources to
monitor the mitten crab?
Mr. Ruiz. At the present time, I would say no. The approach
that we have taken has been to develop an alert system and a
reporting system across the Mid-Atlantic region by having
watermen and fisherman, as well as citizens, report records as
they come across them, taking advantage of the rather large
commercial fishing effort and recreational fishing that occurs
in the Chesapeake and Delaware and the Hudson River. By doing
that, we have learned of over 80 crabs that have been caught
and confirmed.
At the present time I would say that is the extent of the
effort that is being----
Senator Cardin. Well, what worries me is that, if you are
correct, that this all of a sudden you see a huge increase
because of the seasonal aspects to it, we might be faced with a
crisis in the Chesapeake Bay.
Senator Barrasso.
Senator Barrasso. Thank you very much, Mr. Chairman.
Professor Hill, if I could. There is criticism out there of
the existing fish and wildlife framework and that it utilizes a
dirty list. Some say that this approach is too reactive because
it only addresses species after they have been introduced as
harmful. Dr. Ruiz talked about the Lacey Act. Is there any
reason why we cannot work within the Lacey Act to initiate
proactive screening?
Mr. Hill. Senator, there is no reason that the Lacey Act
could not be used to proactively screen species. The screening
of species, I think, is an excellent way of identifying some of
the more potentially problematic species that are out there,
and I think that it could be accommodated in the current
system.
Senator Barrasso. Many of the proposals that address the
threat of invasive species suggest that, aside from those few
species that are exempted like pets and farm animals, there are
thousands of perfectly safe non-native species and they are
going to be blacklisted until a thorough scientific assessment
can prove that they have no impact on the ecology of the United
States. Is this the most prudent course of action?
Mr. Hill. Well, one point is that it is very difficult to
prove that a species will not have some impact onto a system.
There is a lot of scientific uncertainty in this estimation. So
that is one issue that plays into this.
A blacklist approach, or a dirty list approach, seeks to
really focus on those species that are problematic or likely to
be problematic. They do not have to already be a problem to
list a species. And we certainly have those. The State of
Florida, for instance, uses an approach similar to this where
species have been identified as potentially problematic. These
are not species which are already introduced into Florida,
these are species that may be in trade, or have been in trade
in years past, but are not in the environment. And they been
prohibited or placed on a conditional species list. So it is a
workable type of solution.
Senator Barrasso. Let me ask a question about an approved
list and how that would play into this, because some of what
might be some of the most damaging invasive species in the
country are also popular pets. I am not talking about the boa
constrictor that we saw, but popular house pets. How do you
view that whole thing working out?
Mr. Hill. Well, I tend to look at this from terms of risk
and a risk analysis standpoint. When you go through a risk
analysis, you assess risk and what are the bad things that
these organisms may do. But then you also balance those risks
during the management process to determine, do you still want
to have those organisms and do you balance that risk against
the benefits.
There are a number of species that, from a purely
scientific risk assessment standpoint, are clearly problematic.
I am a dog person, but the domestic house cat is probably one
of the No. 1 species in probably all the States, as being an
invasive species when it is in the environment. Obviously,
people love cats and they have societal and economic benefits.
From a purely risk standpoint, cats are problematic. But when
you put the management side to that, then cats would obviously
be a banned species.
Senator Barrasso. Director Humphries, if I could. We had
Senator Levin here who gave great testimony, and he listed you
as the expert from Michigan. He also said that his position in
Michigan was the exact opposite of the position of, I think,
the Michigan legislature. So, as the expert, can you tell all
of us who is right and who is wrong?
[Laughter.]
Ms. Humphries. They are both right.
[Laughter.]
Senator Barrasso. Well, then we have a seat for you right
up here.
[Laughter.]
Ms. Humphries. But I would like to respond that it is very,
very difficult to screen risk, to screen organisms by risk, and
rely on that solely. So, I caution all of us that, when we look
at this, we also need to be nimble, to be able to address when
one of these species or diseases crops up unexpectedly. Because
it is going to go through a filter at some point in time, and
we will have the unexpected. That is one to the things that the
Fish and Wildlife Association has been trying to address, is
making sure that we have both capacities and authorities across
the United States to address these issues adequately.
Senator Barrasso. Thank you, Mr. Chairman. No further
questions.
Senator Cardin. Well, thank you.
Let me, if I could, Mr. Torgan, you talked about regional
cooperation during your testimony. I think about our efforts on
the Chesapeake Bay, which has been regional. We have been able
to get all of the regional governments to work together on a
strategy on the Bay and we could easily bring this subject into
the debate and we have. It has been, I think, an effective way
to deal with it.
As I have listened to the testimony, I see an effort made
by the Federal Government, working with the States on specific
issue problems. I just really want to get your view, and
perhaps others on the panel, as to whether we need to do more
to empower regional approaches to dealing with these issues.
Not just on a crisis basis, or not just where there is a
popular effort that has been supported over a long period of
time, such as the Chesapeake Bay, which has its challenges, but
whether we need to try to institutionalize this in a more
effective way.
Mr. Torgan. Thank you, Senator. I think so. The
Chesapeake's situation and the recent move by EPA to create a
multi-State restoration and protection framework are unique to
the Chesapeake. There is a similar effort now for the Great
Lakes. And we have thought a lot about whether such an approach
would work, for example, for New England or for the Mid-
Atlantic States.
There are a lot of lessons that we could learn in Rhode
Island from what you have accomplished in Maryland and in the
Chesapeake Bay and many of these issues have parallel there.
So, it does make sense to cooperate, collaborate and have
synergy on that. Rhode Island is a small State, obviously, so
our ability to manage and communicate on the State-wide level
is good.
The regional cooperation, the challenges of that have
always had to do with the teeth of whatever regulations compel
interstate partnerships. But we really believe, because these
species do not respect State boundaries, and the issues are, if
not national, then at least regional, that a regional approach
that brings together States, Federal agencies and people
involved on the ground in the universities and in the non-
profit, non-government community who are engaged in this, to
work together for a solution. I think that is the only way to
crack it.
Senator Cardin. We, in this region, look at the Chesapeake
Bay partnership with the Federal Government as an area of major
national priority, but also a model that could be used in other
parts of the country where you have multi-jurisdictional
issues.
Now the Great Lakes is the other area that is frequently
mentioned as where you need to have multiple jurisdictional
impact if you are going to be able to have effective results.
And ,of course, you are also dealing with another country. How
do the Great Lakes manage the governmental challenges of
multiple levels?
Ms. Humphries. Well, the Great Lakes certainly is a
difficult situation because, as you say, you have a number of
political boundaries in there and countries. But, nonetheless,
we get scientists together, as well as policymakers, through
the Great Lakes Commission, the Great Lakes Fisheries
Commission, to set priorities and help address these issues,
including the science on those issues with research priorities.
It has worked very well for us.
There are a number of other models when you look around the
country with this regional approach. The Southeast Disease
Cooperative was established back in the 1950s, where
Southeastern States in the United States banded together in
order to develop a scientific approach to address deer
population problems that were occurring in that area. That
model is still in place.
So, I think there are a number of different models and I
have appended some of those within the Initiative that I
attached to my testimony. They will give you some ideas of some
these regional approaches. They are, I think, the most
effective in the fact that you have partners coming together
and talking about the specific risks in those areas. And also
some of the cultural things that you need to change with your
citizens to address the risk out there.
Senator Cardin. I know that Senator Levin is working on a
reauthorization under the Clean Water Act of the Great Lakes.
We are working on the Chesapeake Bay reauthorization, looking
for more effective ways to enforce the goals that are
established by the local governments. Because we want to make
sure there is not only a partnership with the Federal
Government, but that there is reasonable expectation that we
can achieve the goals that we set. We will be working with all
of you in that regard.
Senator Barrasso, anything further?
Senator Barrasso. No.
Senator Cardin. Well, let me thank our witnesses again for
their testimony and for their participation at this hearing.
This has been a very interesting hearing for, I think, the
members as well as an educational one for the Chairman.
Thank you all very much.
[Whereupon, at 12:08 p.m., the subcommittees were
adjourned.]
[Additional statements submitted for the record follow:]
Statement of Hon. James M. Inhofe,
U.S. Senator from the State of Oklahoma
Good morning. I would like to first welcome Senators Levin
and Nelson, who I know care greatly about the topic of this
hearing this morning. I think that the protection of our native
wildlife from harmful invasive species should receive increased
Federal attention. I would like to thank the subcommittee
Chairmen for holding this important hearing on potential
threats non-native species pose to native wildlife in this
country. However, as we chart a course of action we must be
prudent and avoid prematurely banning species that pose no
threat to the environment.
I understand that the House of Representatives had a
similar hearing on this topic in April, in which a specific
legislative proposal--H.R. 669--was examined to address the
threats of invasive species. It is also my understanding that
this legislation received widespread criticism for casting too
wide a net on pets, sports fishing and other species that
generate billions of dollars in our economy with no
demonstrated threat to the environment. I realize that this
hearing will not be examining a specific piece of legislation,
which I must say makes me skeptical, considering this
committee's habit of marking up bills without a legislative
hearing on the specific proposal--especially one that could put
in place a new, cumbersome bureaucratic process for examining
the threats without consideration of effective laws already on
the books.
Common sense reforms are needed to prevent the importation
or breeding of species that would be harmful to our ecosystem;
however, these reforms must avoid placing burdensome
requirements on the retail and agriculture industries and
sportsmen. I appreciate the efforts of environmental groups,
mainly the Defenders of Wildlife, in attempting to address the
threat posed by non-native species, but I am concerned that
their proposal could harm important sectors of our economy.
Any policy that Congress considers should include a
reasonable risk analysis process that would take into
consideration risk management options for controlling non-
native species. It should not adopt a policy that automatically
bans species until proven safe. Acknowledging similar risk
management processes that are used elsewhere in Federal
agencies would effectively address the issue at hand. We don't
need legislation that bans species that we know are safe.
Invasives legislation should use existing scientific evidence
without requiring industries to unnecessarily spend resources
and time completing scientific testing that tells us what we
already know: the vast majority of non-native species in the
United States are safe and present little or no harm to their
surroundings.
Thank you. I look forward to hearing from our witnesses.
Statement of Hon. Bernard Sanders,
U.S. Senator from the State of Vermont
I am pleased that the Environment and Public Works
Subcommittees on Oversight and Water and Wildlife are holding
today's hearing to discuss threats to native species. In
Vermont we face several such threats, and two in particular I
want to highlight.
Our bats, and bats across the Northeast, are increasingly
susceptible to death from white-nose syndrome. White-nose
syndrome appears to be a fungus that turns their noses and
bodies white and kills with a mortality rate of between 90 and
100 percent in some caves. More than 1 million hibernating bats
have died over the past 2 years. Bats prey on harmful insects
such as mosquitoes which spread disease, and moths and beetles
which damage crops. Bats reduce the need for pesticide use and
are beneficial for the environment.
On May 5th of this year I signed a letter along with 24 of
my colleagues in the Senate and the House asking the Department
of the Interior to provide emergency fiscal year 2009 funding
to respond to this crisis. Summer research is critical to stop
the spread of this disease and develop a cure.
In addition I want to highlight another invasive species
threat that deserves the attention of scientists and the
Administration. That is the threat from the Asian longhorned
beetle. This beetle uses maple trees as a host. Vermont leads
all States in maple syrup production, producing 920,000 gallons
in 2009 and creating millions of dollars in value for Vermont's
economy. I ask that the Administration work with State and
local officials in Vermont and put the appropriate resources
into finding solutions to the spread of Asian longhorned
beetles.
