June 2018 - The National Audubon Society has created research summaries for 274 national park units that describe how projected changes in climate under different emissions scenarios are likely to affect local bird populations.

The briefs offer management implications for the parks, and also list winter and summer climate suitability and the likelihood of potential colonization or extirpation for each species. See the full list of briefs on the Audubon website, or go directly to the ones for San Francisco Bay Area National Parks through the links below.
