Public lands in and around Bighorn Canyon National Recreation Area, Wyoming and Montana were evaluated to identify habitat suitable to support a minimum viable population of bighorn sheep. This dataset identifies areas of POTENTIAL suitable habitat. These data were derived from an analysis of slope (30-90 degrees), distance to water (3.2 km), distance from human use areas, effects of natural and manmade barriers to routine movement, and quality of horizontal visibility. It should be used with additional datasets: 1) BICA_domestic_sheep.e00 which identifies domestic sheep grazing allotments and land areas of concern if located in too close proximity to domestic sheep; 2) BICA_lambing_area.e00 which identifies suitable bighorn sheep lambing habitat; 3) BICA_suitable_bighorn_summer_habitat_ww, which identifies suitable bighorn summer range; and 4) BICA_suitable_bighorn_winter_habitat_ww, which identifies suitable bighorn winter range. This is the second of two analyses. The first analysis was conducted in 1995 and the results are found in the 1999 report issued by NPS and USGS (Singer and Gudorf). This second analysis uses current and improved vegetation data for determining horizontal visibility. This will assist management in determining where to manage vegetation to improve potential bighorn habitat. NOTE: this metadata set was developed in the NBII biological profile, and if imported into ESRI ArcCatalog, the biological profile information will be lost. Maintain along with this dataset, a copy of the metedata (.html or .txt) files found posted on the clearinghouse.
