Sagebrush Ecosystem Conservation and Management:
Ecoregional Assessment Tools and Models for the Wyoming Basins

Wyoming Basin Ecoregional Assessment study area

The Wyoming Basins are one of the remaining strongholds of the sagebrush ecosystem. However, like most sagebrush habitats, threats to this region are numerous. The Wyoming Basins Ecoregional Assessment adds to current knowledge about the regional status of the sagebrush ecosystem, the distribution of habitats, the threats to the ecosystem, and the influence of threats and habitat conditions on occurrence and abundance of sagebrush associated fauna and flora in the Wyoming Basins. Comprehensive methods are outlined for use in data collection and monitoring of wildlife and plant populations. Field and spatial data are integrated into a spatially explicit analytical framework to develop models of species occurrence and abundance for the region. The Wyoming Basins Ecoregional Assessment provides significant new information on distributions, abundances, and habitat relationships for a number of species of conservation concern that depend on sagebrush in the region. The tools and models presented in the Assessment increase our understanding of impacts from land uses and can contribute to the development of comprehensive management and conservation strategies.
