Rapid Ecoregional Assessments examine ecological values, conditions, and trends within ecoregions, which are large, connected areas that have similar environmental characteristics. Examples of ecoregions include the Sonoran Desert and the Colorado Plateau. Ecoregions span administrative boundaries and typically encompass areas much larger than those managed by individual BLM field offices. The ecoregions under assessment range in size from 11 million to 91 million acres.  Assessments of these larger areas provide land managers additional information and tools to use in subsequent resource planning and decision-making.  REAs synthesize existing information, rather than conduct research or collect new data, and are generally completed within 18 months.  REAs identify and answer important management questions; document key resource values, which are referred to as conservation elements, with a focus on regionally-significant terrestrial habitats, aquatic habitats, and species of concern; describe influences from four environmental change agents: climate change, wildfire, invasive species, and development; assess the collective effects of projected trends; identify and map key opportunities for resource conservation, restoration, and development; identify science gaps and data needs; and provide a baseline to evaluate and guide future management actions.
