Bird Conservation Regions (BCRs)
BCRs are geographic designations that have similar land-cover types, bird communities, and resource conservation issues. They are the fundamental biological units through which the NABCI promotes delivery of landscape-scale bird conservation. BCRs provide a consistent spatial framework for evaluation, planning, and in some instances implementation. By employing broad units that are ecologically meaningful to bird populations, conservation efforts can be tailored to support groups of species throughout their range. Land-cover composition, combined with soil characteristics, water chemistry, and wetland hydrology result in functional differences among BCRs that influence distribution and abundance of wetland birds. Understanding these functional differences and trends in key cover types across the JV region is important to making effective conservation decisions.
