DEPARTMENT OF THE INTERIOR
Fish and Wildlife Service
Notice of Intent to Prepare a National Environmental Policy Act
document on the control of invading Spartina alterniflora grass on
Willapa National Wildlife Refuge and surrounding tidelands of Willapa
Bay, Pacific County, WA
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This notice advises the public that the Fish and Wildlife
Service (FWS) intends to gather information necessary for the
preparation of a National Environmental Policy Act (NEPA) document for
the control of invading Spartina alterniflora grass on Willapa National
Wildlife Refuge and surrounding tidelands of Willapa Bay, Pacific
County, Washington. Public scoping meetings to solicit comments from
all interested parties regarding the scope and content of the NEPA
document will also be held. This notice is being furnished pursuant to
the National Environmental Policy Act, implementing regulations, and
FWS policy to obtain suggestions and information from other agencies
and the public on the scope of issues to be addressed in the document.
Comments and participation in this scoping process are solicited.
SCOPING MEETINGS: Public scoping meetings will be held from 7:00 p.m.
to 9:00 p.m. at the Raymond Community Center (323 Third Street,
Raymond, WA) on January 6, 1997, and from 7:00 p.m. to 9:00 p.m. at the
Peninsula Church Center (5000 N. Street, Seaview, WA) on January 7,
1997. Interested agencies, organizations, and individuals are
encouraged to attend either of the scoping meetings to identify and
discuss major issues, concerns, and opportunities that should be
addressed in the NEPA Document. Interested parties are reminded that
the primary purpose of the scoping process is to identify, rather than
debate the significant issues related to the proposed action. In order
to insure that all issues are correctly and completely recorded and
considered, those persons providing oral presentations at the scoping
meetings are encouraged to provide agency representatives with a
written statement to more fully explain their remarks.
FOR FURTHER INFORMATION CONTACT: James A. Hidy, Refuge Manager Willapa
National Wildlife Refuge, HC 01 Box

WRITTEN COMMENTS: Written comments should be addressed to James A. Hidy
(see address provided above) and should be received by January 21,
1997. Written comments will also be accepted at the scoping meetings.
SUPPLEMENTARY INFORMATION: James A. Hidy is the primary author of this
document. The Fish and Wildlife Service, Department of the Interior,
proposes to implement a long-term, integrated pest management (IPM)
program at Willapa National Wildlife Refuge to control and reverse the
invasion of the non-native grass, Spartina alterniflora (Spartina) on
the Refuge and the surrounding tidelands of Willapa Bay.
Spartina is a perennial, deep-rooted saltmarsh species native to
the Atlantic and Gulf coasts of North America. It was introduced to the
West Coast during the 1890s, and is currently found from British
Columbia to northern California. However, the infestation is increasing
most rapidly in Washington, particularly Willapa Bay. In 1991, there
were approximately 2,500 acres of Spartina in Willapa Bay. The grass is
expected to cover over 30,000 acres within 45 years.
Spartina is spreading rapidly over tidelands of the Refuge and
surrounding tidelands. It is degrading and displacing habitat that
supports a diverse community of marine organisms including aquatic
migratory birds, anadromous fish, and invertebrate and plant
communities that support them. Widespread colonization by Spartina
induces major modifications of physical, hydrological, chemical, and
biological estuarine functions. Spartina displaces eelgrass (Zostera
spp.) on mudflats and native vegetation in saltmarshes. Benthic
invertebrate species composition in the intertidal zone changes
substantially as Spartina occupies the tidelands. As Spartina becomes
dominant in the tideland, mudflats are raised and channels are
deepened. This eliminates the gently sloping, bare, intertidal zone
that lies between the saltmarsh and the tidal channels.
Refuge objectives are to protect habitats for wintering and
migrating aquatic birds including ducks, geese, swans, and shorebirds.
The continued spread of Spartina constitutes a significant threat to
those habitats. The proposed action is intended to stop habitat loss
and degradation, and prevent future Spartina recolonization.
Important habitats for meeting Refuge objectives lie within the
Lewis, Porter Point, and Riekkola Units (collectively known as the
southern units), where the Service has fee-simple title to over 2,900
acres of tidelands supporting saltmarsh and mudflat habitats. Other
Refuge-associated tidelands include about 1,600 acres of State-owned
use deed lands adjacent to Long Island. Waterbird habitat value is
being rapidly lost in both areas by Spartina invasions. The proposed
action supports Refuge objectives by protecting and restoring aquatic
bird habitats on Refuge tidelands of the southern units. Refuge
objectives would be further supported through cooperative efforts with
other public and private tideland owners directed at bay-wide Spartina
management.
Four alternatives are being considered in the document.
No Action: Under this alternative, the Service would not
participate in Spartina control on Willapa Bay.
Long-term Integrated Pest Management (Proposed Action): This is a
dynamic approach to pest management which utilizes a full knowledge of
a pest problem through an understanding of the ecology of the pest and
related organisms. Programs are carefully designed under IPM using a
combination of compatible techniques to limit damage caused by the pest
to a tolerable level. In many cases, IPM will utilize combinations of
mechanical, cultural, biological and chemical control techniques to
meet objectives. At this time, biological and cultural techniques are
not available for Spartina control, but they would be considered in the
future.
Physical/Mechanical Controls Only: Physical and mechanical methods
of controlling Spartina are those that physically manipulate the grass
itself, or some aspect of the habitat on which the grass depends in
order to kill the grass or control its spread.
Chemical Controls Only: This alternative would rely exclusively on
application of herbicide (currently, only the chemical glyphosate is
approved for use in the estuary) to Spartina using ground, water-borne,
and/or aerial delivery systems.
Significant issues associated with these alternatives include
potential effects on:
The Physical Environment: Soils and Topography, Hydrology, Water
Quality, Ambient Sound.
The Biological Environment: Vegetation, Wildlife, Fish, Microbes
and Marine Invertebrates, Biodiversity.
Social Environment: Human Health, Perceptions/Concerns, Recreation.
Economic Environment: Tourism, Mariculture and Fisheries.
The environmental review of this project will be conducted in
accordance with the requirements of the National Environmental Policy
Act of 1969, as amended (42 U.S.C. 4371 et seq.), NEPA Regulations (40
CFR 1500-1508), other Federal regulations, and FWS policies and
procedures.
We estimate the NEPA document for this proposal will be made
available to the public in Spring, 1997.
Dated: December 17, 1996.

Acting Regional Director, Region 1, Portland, Oregon.
