Environmental Assessment Frostfire Prescribed Burn BLM Northern
Environmental Assessment of the Frostfire Prescribed Burn BLM Northern Field Office 1150 University Avenue Fairbanks, AK. 99709 BLM Alaska Fire Service P.O. Box 35005 Ft. Wainwright, AK. 99703 No. AK-AFS-EA-99-AA03 April 5, 1999 2 I. Introduction The Bureau of Land Management-Alaska Fire Service (BLM-AFS) proposes to assist in conducting a prescribed burn to meet objectives of the Frostfire Project funded by the National Science Foundation (NSF). BLM-AFS has prepared a Burn Plan (Wilmore, et. al., 1998) (See Attachment A) for approval by the University of Alaska, Fairbanks (UAF) and the State of Alaska Department of Natural Resources (ADNR). BLM-AFS would provide the Incident Commander/Burn Boss and other key positions for burn operation, and provide all command and safety functions during the operation. The research watershed selected for the prescribed burn is the C-4 subwatershed of the Caribou- Poker Creeks Research Watershed (CPCRW) (See Map A) which is part of the Bonanza Creek Long-Term Ecological Research (LTER) Site (See Map B) operated by UAF. BLM-AFS would prepare the C-4 watershed for burning, including developing and constructing helispots, fuel breaks and access trails. BLM-AFS would also provide personnel and equipment during preburn, burn, and mopup operations. The Frostfire Project is a cooperative effort between UAF, the USDA Forest Service Pacific Northwest Research Station (PNW), ADNR, the Canadian Forestry Service, and BLM-AFS. A Memorandum of Understanding (# PNW 98-5124-2-MOU) was signed by all parties in May and June, 1998 to formalize Frostfire cooperative efforts. The Frostfire Project would be a continuation of international fire research activities under the International Boreal Forest Research Association Stand Replacement Fire Working Group, and as part of the LTER program.

Dedicated professional staff located in Anchorage, Fairbanks, and Kenai Fish and Wildlife Offices and the Anchorage Conservation Genetics Laboratory serve as the core of the Program’s fisheries management study efforts. Administrative and technical support is provided by staff in the Anchorage Regional Office. Our program works closely with the Alaska Department of Fish and Game and other partners to conserve and restore Alaska’s fish populations and aquatic habitats. Our fisheries studies occur throughout the 16 National Wildlife Refuges in Alaska as well as off- Refuges to address issues of interjurisdictional fisheries and aquatic habitat conservation. Additional information about the Fisheries Program and work conducted by our field offices can be obtained at: http://alaska.fws.gov/fisheries/index.htm The Alaska Region Fisheries Program reports its study findings through the Alaska Fisheries Data Series (AFDS) or in recognized peer-reviewed journals. The AFDS was established to provide timely dissemination of data to fishery managers and other technically oriented professionals, for inclusion in agency databases, and to archive detailed study designs and results for the benefit of future investigations. Publication in the AFDS does not preclude further reporting of study results through recognized peer-reviewed journals.

Andrews, Fishery Biologist, Palmer George L. Van Wyhe, Fishery Biologist, Glennallen Roger J. Reed, Fishery Biologist, Fairbanks Introduction This report of progress consists of the Job Completion Reports from the State of Alaska's Federal Aid in Fish Restoration Project F-S-R-2, "Sport Fish Investigations of Alaska". The current Project is composed of eighteen separate studies and were designed to evaluate the various aspects of the State's recreational fisheries resources. The information gathered will provide the necessary background data for the development of future programs. During the current segment continued emphasis was placed on overall inventorying of accessible waters and the evaluation of general catch data. Several problems of immediate concern appeared sufficiently defined to warrant independent studies. As a result, two indepen dent creel censuses, one experimental silver salmon egg take and a Resurrection Bay area silver salmon population study were insti gated. Data accumulated from prior jobs dealing with the Arctic grayling has resulted in the formulation of three separate in vestigations during the current segment. The rapid expansion of Alaska's population is being reflected in the ever increasing numbers of "No Trespassing" signs encountered in the vicinity of population centers.

Bradley Moran, Dean, School of Fisheries and Ocean Sciences Michael Castellini, Dean o f the Graduate School Abstract Northern pike Esox lucius is a large, long-lived piscivorous species that are harvested in sport and subsistence fisheries in Alaska. My study described the seasonal movements of northern pike that inhabit the Minto Lakes portion (Goldstream Creek drainage) of the Minto Flats wetland complex, Alaska, from May 2008 through January 2010. Very high frequency (VHF) radio tags (n = 220) were surgically implanted in northern pike in Minto Flats in May 2007, 2008, and 2009, and fish were relocated with fixed telemetry stations and aerial- and boat- based telemetry surveys. Radio-tagged northern pike displayed a distinct spring pre-spawning migration into the Minto Lakes study area, where they remained for the duration of the open- water season. A protracted out-migration occurred between late September and early December, with downstream movements peaking in November and October of 2008 and 2009, respectively.

Stock Characteristics of Humpback Whitefish and Least Cisco in the Chatanika River, Alaska TRENT M
ARCTIC VOL. 65, NO. 1 (MARCH 2012) P. 67 – 75 Stock Characteristics of Humpback Whitefish and Least Cisco in the Chatanika River, Alaska TRENT M. SUTTON1,2 and LORENA E. EDENFIELD1 (Received 10 November 2010; accepted in revised form 24 June 2011) ABSTRACT. Overharvest of humpback whitefish Coregonus( pidschian) and least cisco (C. sardinella) in the Chatanika River, Alaska, during the late 1980s led to collapsed stocks and closure of the fishery. We evaluated the stock characteristics of these two species to determine the extent of recovery. A total of 3207 humpback whitefish and 2766 least cisco were captured during their fall spawning migration in 2008. Humpback whitefish ranged from 188 to 583 mm in fork length (FL) and encompassed ages 5 to 29 years, while least cisco ranged from 215 to 425 mm in FL and their ages ranged from 3 to 14 years. Patterns in growth and length-at-age were similar for both species, and annual mortality rates were 31% for humpback whitefish (age 11 and older) and 44% for least cisco (age 9 and older). Population attributes were within the ranges observed for other North American stocks of humpback whitefish and least cisco. Although the humpback whitefish in the Chatanika River have stock attributes that are consistent with low exploitation and this species appears to have recovered, the least cisco in the river still exhibit many attributes that suggest the cisco stock has not fully recovered. The results of this study indicate that the current allowable harvest limit of 2000 whitefish is cautious and appears to be sustainable.
