Bull Trout Core Area Templates Complete Core Area by Core Area Analysis BULL TROUT CORE AREA TEMPLATES COMPLETE CORE AREA BY CORE AREA ANALYSIS Compiled by: U.S. Fish and Wildlife Service, February 2005 Primary Editors: Wade Fredenberg Creston Fish and Wildlife Center Kalispell, MT Jeff Chan Western Washington Field Office Olympia, WA Contributors: John Bowerman Klamath Falls (Oregon) Fish and Wildlife Office Wade Fredenberg (Kalispell) Montana ES Field Office Bianca Streif, Chris Allen and Brad Goehring (Portland) Oregon Fish and Wildlife Office Peter Lickwar, Jennifer O’Reilly, and Alan Mauer Bend (Oregon) Field Office Paul Bridges Roseburg (Oregon) Field Office John Stephenson and Gretchen Sausen LaGrande (Oregon) Field Office Cary Myler, Chris Reighn, Jeri Wood and Marilyn Hemker Snake River (Idaho) Fish and Wildlife Office Scott Deeds Upper Columbia (Spokane, Washington) Fish and Wildlife Office Jeff Chan and Shelly Spalding Western Washington (Lacey ) Fish and Wildlife Office Judy De La Vergne Central Wahington (Wenatchee) Field Office Selena Werdon (Reno) Nevada Fish and Wildlife Office i INTRODUCTION In order to fully document and support our development of the TEMPLATE FOR FEDERALLY LISTED ENDANGERED AND THREATENED SPECIES, required by the Washington Office for a Five-Year Review, we determined that an updated core area by core area analysis of 121 bull trout core areas would be most useful. We also wished to provide a single source of updated information for referral in conducting the core area conservation Status Assessment. We developed an abbreviated template (see separate Introduction and Methods Report) that outlines, in narrative form, current information on populations and threats, with analysis. Those templates were based on the Service DRAFT guidance for 5-year reviews, but were tailored to provide core-area specific responses for bull trout. We operated under the assumption that responses could be “rolled up” into other broader assessments for the entire species. Service Field staff from throughout the range of bull trout (see list of contributors on cover of this report) provided the updated templates to the 5-year review staff. In total, over 650 pages of updated information are provided for the administrative record, with each of the 121 core areas constituting a separate assessment. These assessments are supported by a compendium of literature and references which are on file in the Portland Regional Office. ii Chapter 2 – KLAMATH RIVER MANAGEMENT UNIT

  • Appendix C Roadless Area Re-Evaluation
    Appendix C Roadless Area Re-evaluation SAWTOOTH NATIONAL FOREST INVENTORIED ROADLESS AREAS Blackhorse Creek Roadless Area No. 0414039 7,709 acres DESCRIPTION This area includes the small northwestern portion of what was the Buttercup Mountain IRA (Roadless Area No. 14018) in the 1987 Sawtooth National Forest Land and Resource Management Plan (Forest Plan). During the Forest Plan Revision roadless area inventory update, the Buttercup IRA was divided into three separate areas because the existing roads that separate them were considered to be too highly developed to meet wilderness standards. The Blackhorse Creek IRA is located in Camas County, within the Fairfield Ranger District, about 13 miles north of Fairfield, Idaho. It is bordered on the north and west by the Ketchum-Featherville Road (Forest Road 227), and on the southwest and southeast by the Little Smoky Creek Road (Forest Road 015). The topography is very steep over much of the area. Precipitation averages from 16 to 20 inches. The elevations range from around 6,200 feet to over 8,400 feet. The slopes are generally vegetated up to the ridgelines with Douglas-fir, subalpine fir, and some lodgepole pine on the northern and eastern slopes. The southern and western slopes are vegetated with mountain shrub-sagebrush-grass communities. The brush communities include snowberry, bitterbrush, and sagebrush. Aspen is present but it is in decline due to fire exclusion and conifer encroachment. CAPABILITY Natural Integrity and Appearance: Natural integrity and apparent naturalness are rated low because of mining activities, improved and unimproved roads along the borders, interior exclusions, and range management activities.

  • Peatlands of the Sawtooth Valley, Custer and Blaine Counties, Idaho
    PEATLANDS OF THE SAWTOOTH VALLEY, CUSTER AND BLAINE COUNTIES, IDAHO by Robert K. Moseley and Robert J. Bursik Conservation Data Center Fred W. Rabe University of Idaho and Linda D. Cazier Palouse-Clearwater Environmental Institute January 1994 Idaho Department of Fish and Game Natural Resource Policy Bureau 600 South Walnut, P.O. Box 25 Boise, Idaho 83707 Jerry M. Conley, Director Cooperative Cost-share Project: Sawtooth National Forest The Nature Conservancy Idaho Department of Fish and Game SNF Purchase Order No. 40-0267-3-0233 ABSTRACT During August through and October, 1993, ecologists from the Idaho Department of Fish and Game's Conservation Data Center and the University of Idaho inventoried the flora and vegetation of peatlands in the Sawtooth Valley, as well as aquatic macroinvertebrates at selected sites. Our survey included lands administered largely by the Sawtooth National Recreation Area, Sawtooth National Forest, and a small part of the Challis National Forest. This investigation was a cooperative Challenge Cost Share project between the Department and the Sawtooth National Forest. We focused on peatland substrates, which are wetlands with a peat or organic substrate, because they are the known sites of many rare plant species and rare wetland communities, much more so than wetlands with mineral substrates. We encountered four rare plants in 14 peatlands of the study area. All species are widespread in boreal regions of the continent, but are disjunct or at the southern edge of their range in Idaho, and are rare here. Our discovery of two populations of spoon-leaved sundew (Drosera intermedia) was surprising; this species was just discovered in Idaho in 1992, from one site in the Selkirk Mountains.

We infer that the advances required reinvigora- tion of moisture transport into the northwestern interior of the United States. Glaciers descended the eastern flanks of the Sawtooth Mountains repeatedly during late Pleistocene time, con- structing an extensive moraine belt at the range front in the Sawtooth Valley. The glacial sequence and the numerous Setting and Context lakes it hosts preserve a detailed record of those fluctuations, themselves a reflection of complex climatic processes during The Sawtooth Mountains comprise one of the highest the last glaciation. In particular, we infer that the chronology ranges in central Idaho. The range trends roughly north-south derived to date reflects strong influences of Pacific moisture and rises to about 3,300 m, exposing Cretaceous granitic rocks delivery on the alpine glacial system. and Paleozoic metasedimentary wall rocks of the Idaho batho- The last glaciation involved dramatic reorganization of lith as well as Eocene granites of the Sawtooth batholith.
