    Fishery Management Plan ALASKA PENINSULA BECHAROF NATIONAL WILDLIFE REFUGES July 1994 Region 7 U.S. Fish and Wildlife Service • Department of the Interior FISHERY MANAGEMENT PLAN ALASKA PENINSULA AND BECHAROF NATIONAL WILDLIFE REFUGES Fiscal Years 1994 - 1998 Prepared By: King Salmon Fishery Resource Office U.S. Fish and Wildlife Service P.O. Box 277 King Salmon, Alaska 99613 May 1994 SUMMARY STATEMENT The Alaska Peninsula and Becharof National Wildlife Refuges Fishery Management Plan (Plan) provides the management direction necessary to ensure conservation of fishery resources and habitat. In addition, the Plan provides for continued use of fishery resources by subsistence, commercial, and recreational users consistent with the purposes for which the Alaska Peninsula and Becharof refuges (Complex) were established and are managed. The Complex's biological and physical environment is described and fishery resources, human use, management history, and major issues and concerns are discussed. This information was obtained from the Refuge Comprehensive Conservation Plans, a literature search, and discussions with Alaska Department of Fish and Game personnel. Objectives and tasks are developed to address the issues and concerns. Federal tasks are assigned priorities and costs for each year of continuation. The Plan encompasses a five year period, at which time it will be revised. Major issues and concerns identified include the following: competition between user groups; incomplete salmon escapement data bases to refine management of the Complex fish populations; and inadequate fishery law enforcement. In some cases, concerns were identified because of the perception that they would develop into serious problems if current levels of use or consumption were allowed to continue or expand.

  • Ugashik Lakes
    Chapter 3 - Region 13: Ugashik Lakes Region 13: Ugashik Lakes Summary of Resources and Uses in the Region Region Boundary Region 13 includes the uplands on a portion of the Alaska Peninsula that includes the Ugashik Lakes and the area eastwards to the boundary of the Lake and Peninsula Borough (Map 3-13). The Region is bounded on the west and north by Region 12, on the east by the Kodiak Island Borough. The southern boundary is generally along the Dog Salmon River corridor. There are no communities in the Region. Except for navigable waterbodies and three sections, there are no other state-owned or selected uplands in Region 13. State Lands: Ownership and Acreage State-owned navigable waterbodies, notably Upper and Lower Ugashik Lakes, dominate the western one-quarter of the Region. Much of the remainder is in Federal ownership and within the Alaska Peninsula National Wildlife Refuge. Native ownership of land is concentrated southwest of Lower Ugashik Lake between the Ugashik River and the Dog Salmon River. The plan applies to 1,541 acres of state-owned uplands. The plan also applies to state-owned shorelands (acreages of shorelands have not been calculated). Physical Geography Region 13 is within the Alaska Peninsula ecological province and encompasses some well dissected but rugged terrain. Drainage is predominantly westward towards Bristol Bay. The principal drainages are the Ugashik Lakes and tributaries including Ugashik, Crooked, Moore, Deer, and Black Creeks. The western portion of the Region rises to the spine of the Alaska Peninsula; thus the highest elevations are attained along the eastern boundary of the Region in the vicinity of Deer Mountain (elev.

Aniakchak TUUGS, Draft Report i Disclaimer The Protected Areas Social Research Unit (PASRU) is associated with the National Park Service Cooperative Ecosystem Studies Unit (NPS PNW CESU) coordinated from the University of Washington (UW) College of Forest Resources. The NPS PNW CESU is part of a larger virtual partnership involving nine federal agencies, 16 universities and the Alaska Department of Fish and Game. The PNW CESU was created in October of 2000 to provide, research, technical assistance, and education to enhance management of natural and cultural resources on public lands in the Pacific Northwest. PASRU, the applied social science program associated with the NPS PNW CESU evolved from the social science program component of the Cooperative Park Studies Unit that operated from the UW College of Forest Resources from 1970 to 2000. The mission of PASRU is to provide social scientific understanding needed to support the sound management and conservation of our national parks and other federally protected areas. PASRU social research projects are intended to provide the appropriate depth and breadth of objective science and scholarly study to meet the information needs of cultural and natural resource managers who encounter complex problems driven by myriad biological, physical, social, cultural and economic forces.

  • Fish and Wildlife Harvests in Pilot Point, Ugashik, and Port Heiden, Alaska Peninsula, 1986-1987
    FISH AND WILDLIFE HARVESTS IN PILOT POINT, UGASHIK, AND PORT HEIDEN, ALASKA PENINSULA, 1986-1987 bY James A. Fall and Judith M. Morris Technical Paper No. 158 This research was partially supported by ANILCA Federal Aid Funds, adminis- tered through the U.S. Fish and Wild- life Service, Anchorage, Alaska Alaska Department of Fish and Game Division of Subsistence Juneau, Alaska November 1987 ABSTRACT This report describes the harvest and use of wild fish, game, and plant resources in three communities of the northern Alaska Peninsula -- Pilot Point, Ugashik, and Port Heiden. It is based on research conducted by the Division of Subsistence, Alaska Department of Fish and Game, primarily in May 1987. A major purpose of the project was to collect information on local harvests of migratory waterfowl, including those harvests which occur in spring. Using a standardized questionnaire, division researchers interviewed 17 households in Pilot Point (94.4 percent of the year-round households in the community), five households in Ugashik (100 percent), and 37 households in Port Heiden (100 percent). The results of the interviews which are presented in this report include information on community demography, employment, monetary income, involvement in commercial fishing, percentage of the sampled households using, attempting to harvest, harvesting, receiving, and giving away wild resources, harvest quantities, timing of harvests, and harvest areas. The study period included June 1986 through May 1987. Pilot Point's population in May 1987 was 64; of the 61 people in the surveyed househoLds, 88.5 percent had Alaska Native ancestry. During the study period, 87.5 percent of the adults in the Pilot Point sample were employed, during an average of 8.5 months.

  • Region 15: Cinder River, King Salmon River
    Chapter 3 – Region 15: Cinder River, King Salmon River Region 15 Cinder River, King Salmon River Summary of Resources and Uses in the Region Region Boundary Region 15 includes the state uplands on a portion of the Alaska Peninsula generally southeast of Pilot Point and north of Port Heiden; it also includes tidelands on both the Bristol Bay side and the Pacific Ocean side of the Alaska Peninsula, northwest and southeast respectively (Map O-3). The upland areas contain most of the Cinder River, and King Salmon drainage system. The Region encompasses portions of the Alaska Peninsula National Wildlife Refuge. There are no communities within the Region. State Lands: Ownership and Acreage State-owned land dominates the western one third of the Region while much of the eastern two- thirds is Federally owned. Native-owned land is only a small percentage of the Region and is concentrated on the northern and southern boundaries. The Cinder River Critical Habitat Area is contained within Region 15. The plan applies to 513,061 acres of state-owned and state- selected uplands and 439,401 acres of state-owned tidelands in this region. The plan also applies to state-owned shorelands (acreages of shorelands have not been calculated). Physical Geography The western portion of Region 15 is within the Bristol Bay Lowlands ecological province; the eastern portion of the Region is in the Alaska Peninsula ecological province. Drainage flow is predominantly westward towards Bristol Bay and eastward toward the Pacific Ocean. The principal drainages are the Dog Salmon, King Salmon, and Cinder Rivers, which flow westward from the National Wildlife Refuge.
