Endangered and Threatened Wildlife and Plants; Notice of Finding
on a Petition to Add Pinus albicaulis (Whitebark Pine) to the List of
Threatened and Endangered Species.
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of petition finding.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) announces a 90-
day finding for a petition to amend the List of Endangered and
Threatened Wildlife and Plants. The Service finds that the petitioners
have not presented substantial information indicating that listing
Pinus albicaulis (whitebark pine) may be warranted.
DATES: The finding announced in this notice was made on January 13,
1994. Comments and information concerning this petition finding may be
submitted until further notice.
ADDRESSES: Questions, comments, or information concerning this petition
should be sent to the Field Supervisor, U.S. Fish and Wildlife Service,
2617 East Lincolnway, suite A, Cheyenne, Wyoming 82001. The petition,
finding, and supporting data are available for public inspection, by
appointment, during normal business hours at the above address.

SUPPLEMENTARY INFORMATION
Background
Section 4(b)(3)(A) of the Endangered Species Act (Act) of 1973, as
amended (16 U.S.C. 1531 et seq.), requires that the U.S. Fish and
Wildlife Service (Service) make a finding on whether a petition to
list, delist, or reclassify a species presents substantial scientific
or commercial information to demonstrate that the petitioned action may
be warranted. This finding is to be based on all information available
to the Service at the time. To the maximum extent practicable, this
finding is to be made within 90 days of the receipt of the petition,
and the finding is to be published promptly in the Federal Register. If
the finding is positive, the Service also is required to promptly
commence a review of the status of the involved species.
The Service has made a 90-day finding on a petition to list Pinus
albicaulis (whitebark pine). The petition, dated February 5, 1991, was
submitted by the Great Bear Foundation, Missoula, Montana, and was
received by the Service on February 11, 1991. The petitioners requested
that the Service list the whitebark pine as endangered in western
Montana, northern Idaho, western Wyoming, and northeastern Washington,
and as either threatened or endangered in the Cascade region of Oregon
and Washington, and that critical habitat be designated.
Under the Act, the Service is required to address the status of
plant species over their entire range (unlike vertebrate species where
distinct population segments may be listed). Therefore, the Service
views the petition as a petition to list the whitebark pine throughout
its range, which extends from central California to western Wyoming,
north through Oregon, Washington, and Montana to Alberta and British
Columbia.
The petitioner submitted information and literature references on
the status of the whitebark pine, stating that in significant portions
of the species' range, populations are declining so rapidly that the
ability of the tree species to regenerate itself is in question. The
petition identifies three major factors involved in the ``precipitous''
decline of the whitebark pine: white pine blister rust (Cronartium
ribicola), mountain pine beetle (Dendroctonus ponderosae), and fire
suppression. The petition indicates that white pine blister rust, an
introduced disease, has become established throughout most of the
whitebark pine's range with ``extensive'' infestation and mortality
occurring in the moist mountain regions of Montana, northern Idaho,
Oregon, and the Washington Cascades. The petition also states that
mountain pine beetle infestations have had devastating effects on
whitebark pine populations in Montana and Wyoming. The petitioner also
points out that fire suppression has played a role in the population
decline by allowing other tree species to invade whitebark pine habitat
and replace it, as well as facilitating the spread of white pine
blister rust and mountain pine beetle infestation.
While recent mountain pine beetle infestations have killed most of
the mature trees in some areas (Reynolds 1990), infestations appear to
reach epidemic levels only where specific conditions exist. Whitebark
pine populations have been severely reduced by white pine blister rust
in many moist mountain habitats where the climate allows the blister
rust to complete its life cycle (Kendall and Arno 1990). However, in
drier portions of the whitebark pine's range, climatic conditions are
not favorable for infection, and damage due to white pine blister rust
is negligible (Charles Wellner, retired U.S. Forest Service, in litt.,
1991). Thus, throughout portions of its range, the whitebark pine
remains common in suitable habitats and/or populations do not appear to
be declining (Dr. Clinton Williams, U.S. Forest Service, in litt.,
1991; Chester Buchanan, U.S. Fish and Wildlife Service, in litt., 1991;
R.T. Ogilvie, Royal British Columbia Museum, pers. comm., 1992).
The Service has reviewed the petition, the literature cited in the
petition, other available literature and information, and has consulted
with biologists and researchers familiar with the whitebark pine. After
reviewing the best scientific and commercial information available, the
Service finds the petition does not present substantial information
that listing the whitebark pine may be warranted. In making this
finding, the Service does recognize that white pine blister rust,
mountain pine beetle infestations, and successional replacement and
competition by more shade-tolerant conifers do pose a real threat to
the whitebark pine in portions of its range. Some whitebark pine
populations have undergone dramatic declines due to one or a
combination of these factors, and the degree of population decline may
be severe in local or, in some cases, over broad geographic areas.
However, in other portions of the species' range, where different
climatic conditions exist, these same factors are not stand-
threatening, and healthy whitebark pine stands continue to persist.
Whitebark pine is usually restricted to remote, higher elevation
areas and generally is not valued as a timber species. Consequently,
little inventory or monitoring work has been completed in much of its
range. In many areas, there are little or no quantitative data on its
distribution, status, or the extent of decline due to the various
factors mentioned above. However, available data do not indicate the
species may be threatened or endangered throughout a significant
portion of its range.
In regard to the petitioner's request that critical habitat be
designated for the whitebark pine, the designation of critical habitat
is not a petitionable action under the Act.
