Information on the potential effects of climate change on bird communities can help guide effective conservation and inform land management decisions. Species projections can be used to identify species that may be sensitive and vulnerable to climate change. Species projections can also be used to examine future changes in bird species richness and composition. These models were created under a grant from the North Pacific Landscape Conservation Cooperative (NPLCC) and will be used within that region to help identify areas of current and future conservation priority as well as to reveal opportunities for resource managers to collaborate in their climate adaptation strategies.
