This collection of maps shows relative habitat quality for a suite of species that use riparian overstory habitats. Component layers include: tree patch size, presence and complexity of riparian understory, and abundance of tamarisk. Associated layers such as river channels at high flow and bottomland reaches are included for reference.

This dataset contains the predicted distributions of 445 terrestrial vertebrate species in Wyoming, created in a GIS modeling process using species habitat assocation rules in combination with species geographic range. Because of the large size of this dataset, it is distributed in two ways (complete, statewide), and tiled into 56 1:100,000-scale quadrangles units which are small enough to be utilized in the PC Arc/Info or ArcView environment.

This individual species distribution is derived from a GIS modeling process using species habitat association rules in combination with species geographic range. There are a total of 445 individual terrestrial vertebrate species distributions generated for Wyoming by the Wyoming Gap Analysis project.

The following vegetation map units were combined and recoded to 1 if they occurred on slopes less than or equal to 10%: Apacherian-Chihuahuan Semi-Desert Grassland and Steppe, Chihuahuan Loamy Plains Desert Grasslands, Apacherian-Chihuahuan Mesquite Upland Scrub, Chihuahuan Creosotebush Desert Scrub, and Agriculture. The extents of the map units were limited to HUC boundaries that included historic locations of black-tailed prairie dog towns and/or expert opinion. In some cases, there were HUCs that did not have evidence of historic towns, but were considered to contain sufficient habitat types to include within the model. In other cases, there was limited habitat and the boundaries of the HUC were clipped to include...
