Mapping broad regional distributions of a species can be limited by availability of consistent data. Statistical models also face trade-offs between model fit and prediction: results derived from local studies often fail when applied to new environments outside the original inference space. We used a method first described in 1901 to identify basic requirements of greater sage-grouse (food, cover, space, and water only a little more complicated). We mapped an index of similarity to identify areas that met this basic set of requirements. Then, we created maps of potential corridors among delineated populations under the assumption that resistance to dispersal movements was inversely related to a location's minimum chacteristics. When coupled with range-wide information on gene flow currently being developed, we will have a powerful understanding of connectivity among populations and likely corridors used by dispersers.
