GAP distribution models represent the areas where species are predicted to occur based on habitat associations. GAP distribution models are the spatial arrangement of environments suitable for occupation by a species. In other words, a species distribution is created using a deductive model to predict areas suitable for occupation within a species range. To represent these suitable environments, GAP compiled existing GAP data, where available, and compiled additional data where needed. Existing data sources were the Southwest Regional Gap Analysis Project (SWReGAP) and the Southeast Gap Analysis Project (SEGAP) as well as a data compiled by Sanborn Solutions and Mason, Bruce and Girard. Habitat associations were...

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.

We propose to identify future risk of wildlife population decline for species inhabiting the Rio Grande, New Mexico. Specifically, we will examine and quantify the interactive effect of fire and climate change on the presence and long-term persistence of native and nonnative species in residing within Rio Grande riparian and wetland habitats. We will build upon recent species vulnerability assessment work conducted for the Rio Grande and incorporate new data and model output regarding fire behavior under different climate scenarios. Predictions for future species distributions will be coupled with scores representing species adaptive capacity to quantify vulnerability to changing climate and disturbance regimes....

Prairie ecosystems and the grassland birds that rely on them for habitat may be particularly vulnerable to rapid changes in climate. Extensive portions of prairie have already been lost due to agriculture and urbanization, and as a result grassland birds have declined more than any other bird group in the last four decades. Now, climate change could exacerbate existing threats to these birds as temperatures in certain prairie ecosystems are expected to rise and extreme weather events, such as drought, could become more common. The goal of this project is to better understand the current and future impacts of climate change on grassland bird species, such as the Henslow’s Sparrow and the Bobolink. To do this, researchers...

Fire is critical to maintaining and restoring temperate ecosystems in the South Central U.S. As precipitation patterns and temperatures change in the region, managers require information on how these changes will impact fire frequency, and thus the species and ecosystems within the landscape. To address this need, researchers will use climate model data to predict and map future changes in fire frequency for Texas, Oklahoma, and New Mexico. Researchers will then examine species and ecosystem distribution data to understand the relationship between climate, fire frequency, and species occurrence. This analysis will enable researchers to identify potential future distributions of woody ecosystems and species such...

Changing temperature and precipitation patterns in the South Central U.S are already having an impact on wildlife. Hotter and drier conditions are prompting some species to move in search of cooler conditions, while other species are moving into warmer areas that were once unsuitable for them. These changes in the distribution of wildlife populations present challenges for wildlife managers, hunters, tribal communities, and others who are making decisions about wildlife stewardship. This project examined the effect of shifting climate conditions on 20 species of conservation concern in the South Central United States. These species, which include the black-tailed prairie dog and the lesser prairie-chicken, were...
