Sage-grouse habitat areas divided into proposed management categories within Nevada and California project study boundaries. HABITAT CATEGORY DETERMINATION The process for category determination was directed by the Nevada Sagebrush Ecosystem Technical team. Sage-grouse habitat was determined from a statewide resource selection function model and first categorized into 4 classes: high, moderate, low, and non-habitat. The standard deviations (SD) from a normal distribution of RSF values created from a set of validation points (10% of the entire telemetry dataset) were used to categorize habitat ‘quality’ classes. 1) High quality habitat comprised pixels with RSF values < 0.5 SD. 2) Moderate > 0.5 and < 1.0 SD. 3)...

This polygon data set represents all sage-grouse Priority Areas for Conservation (PACs) identified in the 2013 Greater Sage-Grouse Conservation Objectives Team (COT) Report. PACs represent areas identified as essential for the long-term conservation of the sage-grouse. The COT determined that the PACs are key for the conservation of the species range wide. PAC polygons were provided by States. This data set has merged all State PACs together and cleaned up the polygons by filling in small gaps along state borders, closing any holes less than 10 acres, and removing any polygons less than 10 acres. This cleaning reduced noise in the data. PACs were then split by population using the ‘GRSG_2015_USFWS_StatusReview_Populations’...

This data set represents Greater Sage-Grouse Current Range to be used in work for the USFWS 2015 Status Review for the Greater Sage-Grouse. Current Range is defined as areas believed to be currently occupied. Therefore this data set represents occupied habitat for Greater Sage-Grouse. Current range for this data set was created by compiling the following data and information Schroeder et al. 2004 current range Priority Areas for Conservation (PACs) identified in the Conservation Objectives Team (COT) Report, 2013. One small polygon from the Schroeder et al. 2004 current range was removed as it was determined that it no longer represents current range. Determination made from information from Oregon Department...

This data set represents greater sage-grouse populations to be used in work for the US Fish and Wildlife (USFWS) 2015 Status Review for the greater sage-grouse. Populations do not represent occupied habitat. Population polygons are meant to coarsely identify areas of occupation based on encircling groups of leks. Boundaries taken from BLM/WAFWA revised population boundaries (‘COT_SG_Populations_2014_WAFWA_UT’ data layer). The original data layer was slightly modified for the USFWS 2015 Status Review. Modifications include dissolving populations across State boundaries and merging several polygons together. Five additional polygons were added to the data set including four polygons in Utah and one polygon in Canada....

Emerging applications of ecosystem resilience and resistance concepts in sagebrush ecosystems allow managers to better predict and mitigate impacts of wildfire and invasive annual grasses. Soil temperature and moisture strongly influence the kind and amount of vegetation, and consequently, are closely tied to sagebrush ecosystem resilience and resistance (Chambers et al. 2014, 2016). Soil taxonomic temperature and moisture regimes can be used as indicators of resilience and resistance at landscape scales to depict environmental gradients in sagebrush ecosystems that range from cold/cool-moist sites to warm-dry sites. We aggregated soil survey spatial and tabular data to facilitate broad-scale analyses of resilience...

Sage-grouse habitat areas divided into proposed management categories within Nevada and California project study boundaries. MANAGEMENT CATEGORY DETERMINATION The process for category determination was directed by the Nevada Sagebrush Ecosystem Technical team. Sage-grouse habitat was determined from a statewide resource selection function model and first categorized into 4 classes: high, moderate, low, and non-habitat. The standard deviations (SD) from a normal distribution of RSF values created from a set of validation points (10% of the entire telemetry dataset) were used to categorize habitat ‘quality’ classes.

This data set identifies Management Zones to be used in work for the USFWS 2015 Status Review for the greater sage-grouse. Management Zone boundaries in this data set were slightly adjusted from the 2006 WAFWA Management Zone data set. Outer boundaries were adjusted to include all PACs and Populations from the 'GRSG_2015_USFWS_StatusReview_Populations' data set. Management Zone boundaries dividing populations were adjusted to match Population boundaries from the 'GRSG_2015_USFWS_StatusReview_Populations' data set. See the Supplemental Information for more details.

This raster represents a continuous surface of sage-grouse habitat probability values for Nevada and California. These values are derived from modeling the resource selection function (RSF) for the region (see supplemental information in the Open File Report cited below for more details). Higher values indicate a higher probability of quality sage-grouse habitat. NOTE: This file does not include habitat for the Bi-State management area. This dataset is associated with the following Open-File Report; Coates, P.S., Casazza, M.L., Brussee, B.E., Ricca, M.A., Gustafson, K.B., Overton, C.T., Sanchez-Chopitea, E., Kroger, T., Mauch, K., Niell, L., Howe, K., Gardner, S., Espinosa, S., and Delehanty, D.J., 2014, Spatially...
