Bird Conservation Regions, Northern Appalachians

Bird Conservation Regions (BCRs) are ecologically distinct regions in North America with similar bird communities, habitats, and resource management issues. These ecoregions encompass areas that are similar in their biotic (e.g., plant and wildlife) and abiotic (e.g., soils, drainage patterns, temperature, and annual precipitation) characteristics.

Bird Conservation Regions were developed initially from 1998 to 1999 by a mapping team comprising members of the United States, Mexico, and Canada.  BCR’s were defined through a process of expert consultation whereby CEC polygons from various scales were combined or split to create units corresponding to bird species distribution and requirements, and recognizing practical planning  considerations.  It was understood that updates to the BCR layer would be made every three years, but this did not begin to occur in an official capacity until 2009.
