Item Open Access Beaver Creek watershed analysis(2001-10) Waldport Ranger District (Or.)As required by the Northwest Forest Plan, the analysis discusses the ecological processes at work in the watershed, and focuses on older forests and coho salmon. Includes issues, findings, recommendations, and organizations providing assistance.Item Open Access Bend Watershed analysis(1998-09-30) Deschutes National Forest (Agency : U.S.)Provides characterization and maps of watershed, issues and key questions, historic and current conditions, trend and interpretation, and management recommendations.Item Open Access Big Marsh Watershed analysis(1997-06) Deschutes National Forest (Agency : U.S.)Provides analysis to develop conceptual strategies to sustain viable ecosystems, divided into three domains: physical, biological, and social. Includes background information, existing conditions, trends and analysis, landscape goals and opportunities.Item Open Access Canyon Creek watershed analysis: Ecosystem analysis at the watershed scale(2003-06-20) Blue Mountain Ranger District (Or.); David Evans and Associates; Duck Creek AssociatesCharacterizes ecological and physical processes at multiple spatial scales by systematically uncovering the interactions of biological, physical, and human processes that have created current conditions. Identifies key questions and conditions, investigates and describes conditions, describes reference conditions, synthesizes and interprets the information, and provides recommendations and management options.Item Open Access Cascade Lakes Watershed analysis(1995-10-05) Deschutes National Forest (Agency : U.S.)Analysis provides current and future trends of the watershed as compared to historic conditions, past uses such as recreation, timber harvest, and range or grazing practices, and past disturbance events such as wildfire, insect and disease epidemics.It presents management goals and future opportunities to prevent ecologically undesirable catastrophic events, maintain physical and biological integrity, and restore ecosystem function to deteriorated areas.Item Open Access Desolation ecosystem analysis and Upland Forest vegetation analysis(1999-07-02) Umatilla National Forest (Agency : U.S.)Upland analysis identifies ecological processes of greatest concern, establishes how well these processes are functioning, and then determines the conditions or circumstances under which restoration and other management activities could occur in the watershed. Findings of ecosystem analysis for Desolation watershed include: available target maximum standard water temperature for tributaries should be 55-60 degrees F, the watershed has a high concentration of Botrychium; non-native seeded grasses occupy a high proportion of meadow cover; riparian obligate plant species are underrepresented; current noxious weed infestation is low; opportunities for use of natural fuels treatment are limited; old forest structure is much below historic levels; existing C1/C2 old growth network contains no old forest; and reproductive habitat for pileated woodpeckers and American martin has become rare.Item Open Access Forks/Bridge Watershed analysis(1995-04) Deschutes National Forest (Agency : U.S.)Provides overview of watershed; identifies issues, key trends, causes, and resources at risk; and lists goals and opportunities by domain.Item Open Access Galena Watershed analysis--Supplement 2002(2003-01-03) Blue Mountain Ranger District (Or.)Provides a mid-scale review of 7 subwatersheds in the Middle Fork of the John Day River in supplement to Ecosystem Analysis at the Watershed Scale--Galena Watershed Analysis (1999). Describes the five alternatives of recommended actions for the Southeast Galena Restoration. Early season peak flows have been exacerbated by wildfire adjacent to the area, and has caused elevated stream temperatures during dry months when threatened species of fish depend upon cool water to spawn. Also, the habitat for wildlife has been deteriorating because overstocked, dense stands of trees have inhibited vegetation in the understory that once provided high quality forage for deer and elk. Actions considered include using heavy equipment within stream channels reversing adverse hydraulic and vegetation trends, riparian planting, prescribed harvest and fire, and road decommisioning, closing, and reconstruction.Item Open Access Metolius Watershed analysis update(2004-08) Sisters Ranger District (Or.)Updates 1996 analysis, and serves to support changed condition analysis for the Metolius Basin Forest Management Project in a watershed that was partially burned, and identifies recommendations for future management activities. Includes sections on soils, aquatic/fisheries, vegetation, insects and disease, fire and fuels, botany and noxious weeds, wildlife, heritage, scenery management system, recreation, transportation, access, and roads data.Item Open Access Odell pilot watershed analysis(1994) Deschutes National Forest (Agency : U.S.)Provides analysis focusing on the three basic domains (physical, biological, and social) and the four key issues of the watershed: viability of indigenous fish, recreational use, soil quality, and vegetative structure. Includes orientation and context, data gathering and analysis, synthesis and integration, and landscape goals and opportunities.Item Open Access Odell Watershed analysis(1999-10) Crescent Ranger District (Or.)Provides analysis focusing on the three basic domains (physical, biological, and social), while noting changes relating to wildlife species in the five years since the pilot analysis. These include the proposed listing of the Canada lynx under the Endangered Species Act, the proposed delisting of the Bald Eagle, and the delisting of the peregrine falcon, and the listing of the bull trout. Also considers the effects of the Oregon DEQ's decision to place Odell Lake on its list of water quality impaired waterbodies.Item Open Access Phillips-Gordon ecosystem analysis and Upland forest vegetation analysis(2001-10) Walla Walla Ranger District (Wash.)Vegetation analysis considers various treatment recommendations, including salvage of dead trees, planting, thinning, improvement cutting in stands where the early-seral species still exist, forest regeneration on dry-forest sites where early-seral species no longer exist, understory removal/thinning, pruning, and prescribed fire. Ecosystem analysis recommendations list priority subwatersheds, enhancement of minor forest species, prescribed fire, road system upgrades to improve water quality, riparian revegetation, introduction of woody debris and fish passage restoration, noxious weed control, and maintenance or restoration of late/old forest structure.Item Open Access Potamus ecosystem analysis(2004-12) Heppner Ranger District (Or.); North Fork John Day Ranger District (Or.)Provides analysis of historic and current physical and biological conditions of the watershed. Hydrology concerns include maintaining and improving adequate water supplies, maintaining and restoring water quality, and improving overall conditions of streams, floodplains, and riparian ecosystems. Other topics include aquatics, upland forest vegetation, wildfire risk, botanical resources, noxious weeds, vertebrates, fire and fuels, non-forest vegetation, and rare plants.Item Open Access Sisters/Why-chus Watershed analysis(1998) Sisters Ranger District (Or.)Provides analysis focusing on the three basic domains (physical, biological, and social), while following the federally-mandated six-step analysis process. This includes watershed characterization, issues and key questions, description of current conditions, description of historic reference conditions, synthesis and interpretation of differences and trends, and recommendations.Item Open Access Snow Lakes Watershed analysis(2005-10) Bend-Fort Rock Ranger District (Or.)Updates two earlier analyses: Cascade Lakes (1995) and Browns/Wickiup (1997). Focuses on the three basic domains (physical, biological, and social), while following the federally-mandated six-step analysis process: watershed characterization, issues and key questions, description of current conditions, description of historic reference conditions, synthesis and interpretation of differences and trends, and recommendations.Item Open Access Tucannon ecosystem analysis(2002-08) Pomeroy Ranger District (Or. and Wash.)Provides analysis of Umatilla National Forest lands within the watershed, characterizing the historic and current biotic and abiotic conditions. Findings include a declining vegetation diversity, 55% of the upland forest has tree densities exceeding recommended levels, wildfire risks are severe in many sections, the Tucannon River has become wide and shallow without woody material and possessing degraded fish habitat, roads continue to contribute sediment and create some channel instability, twelve invasive weed species are present, the clustered lady slipper is the only Forest Sensitive Plant present, 173 historic properties have been located, one endangered and two threatened species are on the Forest Plan list, the total amount of late-old structure is below desirable levels, and prescribed burning should be performed periodically to maintain forage quality.Item Open Access Umatilla and Meacham ecosystem analysis and Upland forest vegetation analysis: Umatilla and Meacham watersheds(2001-04) Umatilla National Forest (Agency : U.S.); Powell, David C.Ecosystem analysis finds the watersheds are a critical source of relatively cool water for the entire Umatilla Subbasin, the Umatilla River and Meacham Creek provide some areas of relatively high quality conditions for remnant and recovering fish populations, bull trout populations are at risk because of their small population and limited satisfactory habitat with less than ideal water temperature conditions, coldwater source protection may conflict with high priority vegetation management activities, overstocked stands with dense understories invite wildfires, a high risk of infestation exists from western spruce budworm and Douglas-fir tussock moth, and ten native plant species are at risk. Vegetation analysis describes the potential vegetation, cover types, size classes, structural stages, density (canopy cover), and disturbance processes. Also includes the historical range of variability for forest structural stages, consideration of limited vegetation components, and an assessment of and suggestions for stocking levels for various tree species.
