Why are Some Gap Projects Regional?

Published Jul 8, 2010

Regional land cover mapping provides the context for mapping predicted distributions of vertebrate habitat. The assumption is that a species is likely to occur where its habitat occurs within its range. Compiling habitat descriptions from various parts of its range (different states) provides a refined picture of where the species occur within broad range limits.

An example of a regional GAP project is the Southwest ReGAP effort – a multi-state, multi-cooperative project to assess biodiversity and conservation gaps across the Southwestern United States conducted in the mid-2000s. The effort was coordinated among five state-based institutions and their cooperators, the U.S. Environmental Protection Agency and the Bureau of Land Management.
