The Southern Great Plains Crucial Habitat Assessment Tool (SGP CHAT) is a dynamic online mapping application created by a coalition of states at the request of the Western Governors Association’s Wildlife Council to provide information on lesser prairie-chicken (LEPC) habitat (and other species in coming years) to help facilitate responsible development of natural resources. The SGP CHAT encompasses those portions of Colorado, Kansas, New Mexico, Oklahoma, and Texas that fall within the historic range of the LEPC. Representatives from each state worked together to acquire the best bio-geophysical data available for the region to model the habitat probability and identify important movement corridors within and between meta populations.
