Central Basin and Range Rapid Ecoregional Assessment (CBR REA)

About

The Rapid Ecoregional Assessments (REAs) seek to identify important resource values and patterns of environmental change that may not be evident when managing smaller, local land areas. REAs look across all lands in an ecoregion to identify regionally important habitats for fish, wildlife, and species of concern. REAs then gauge the potential of these habitats to be affected by four overarching environmental change agents: climate change, wildfires, invasive species, and development (both energy development and urban growth).

REA reports and associated geospatial data represent regional scale information and models about resources and change agents. This information is non-decisional but does provide context for cross-jurisdictional, multi-scale resource discussions, potential future conditions, and the basis to prioritize additional information needs.

The attached final report summarizes key results of the REA. The body of the report provides a summary section on methods used to generate the results. Extensive appendices provide complete details on methods and data used and data products delivered to BLM contain further details in their metadata. After this section is a summary of Key Limitations and Data Gaps that users of the REA products should be aware of to properly apply these products; specific limitations are provided in the report chapters.

BLM provided specific criteria for delineating the geographic extent of REAs: the level III ecoregion delineation of the Commission for Environmental Cooperation and all 5th level Hydrologic Units (HUCs) that intersect the ecoregion boundary. The resulting CBR ecoregion is delineated in many of the included spatial files. Including the buffer, it is approximately 138,945 miles2 or 359,869 km2 in size; BLM manages 58% of the ecoregion.
