Description / Table of Contents: In July 2016, Audubon Alaska completed a long-term effort to integrate the best available science into a series of maps highlighting key resources within Alaska's Western Arctic. The resulting publication, the Ecological Atlas of Alaska's Western Arctic, helps the reader explore the land­scape and better understand the overlap of wildlife, people, and development to inform conservation and management.
