Cheatgrass began invading the Great Basin about 100 years ago, changing large parts of the landscape from a rich, diverse ecosystem to one where a single invasive species dominates. Cheatgrass is highly flammable; consequently, cheatgrass-dominated areas experience more fires that burn more land than in native ecosystems, resulting in economic and resource losses. Therefore, the reduced production, or absence, of cheatgrass in previously invaded areas during years of adequate precipitation could be seen as a windfall. However, this cheatgrass dieoff phenomenon creates other problems for land managers such as accelerated soil erosion, loss of early spring food supply for livestock and wildlife, and unknown recovery...
Habitat and population fragmentation were considered as one of the top factors contributing to the recent U.S. Fish and Wildlife Service decision that listing greater sage-grouse was warranted but currently precluded. This study provides an approach that combines genetic markers and landscape analyses to delineate populations, estimate fragmentation and connectivity in sage-grouse populations, and potentially identify underlying causes that limit connectivity and isolate populations. State and federal agencies are focusing current management actions for greater sage-grouse in core areas containing the highest densities of breeding birds. The core area approach permits limited resources to be applied in regions that...
This is the temperature data used in the science product "Spatio-temporal variability in movement, age, and growth, of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry." Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279. This study took place on the Methow River watershed. Some of the fish from this study moved into the Columbia and Entiait rivers.
Habitat and population fragmentation were among the primary factors contributing to the recent U.S. Fish and Wildlife Service decision that listing greater sage-grouse (Centrocercus urophasianus, hereafter sage-grouse) was warranted but currently precluded by higher priority actions. Increasingly, current management is focused on core or priority areas containing the highest densities of breeding birds with little regard to understanding connectivity within and among areas. The most fundamental objective of species conservation is to first identify and subsequently maintain a set of viable and connected populations. Therefore, if management emphasis on core areas is to be successful for long-term conservation, it...
This update was provided to FWS on March 21, 2013. The assessment incorporates an evaluation of climate and non-climate threats, and potential interactions among them to evaluate potential bull trout persistence. In summary, it includes the following steps: 1) Map suitable habitat "patches" across the species' range in the conterminous United States; 2) Attribute patches with information on local and climate related threats; 3) Map and attribute migratory habitats for the species and their relationship to "patches;" and 4) model persistence of bull trout in relation to local and climate related threats in patches and migratory habitats. For more information, contact Jason Dunham, U.S. Geological Survey, Forest...

This archive contains two datasets. Both cover the northwestern United States and part of southern British Columbia (N of about 38 degrees N and W of about 105 degrees W) at 1/16th (0.0625) degree resolution. Climate and hydrologic variables (21 total) in each are as follows: precipitation, temperature (avg./max./min.), outgoing longwave radiation, incoming shortwave radiation, relative humidity, vapor pressure deficit, evapotranspiration, runoff, baseflow, soil moisture (3-layers), snow water equivalent, snow depth, and potential evapotranspiration (5 vegetation references). The first dataset, "Western US Hydroclimate Scenarios Project Dynamically Downscaled Data", contains daily dynamically downscaled climate...
