JACKSON, Wyo. (AP) — The Northern Rockies Conservation Cooperative has awarded its Craighead Conservation Award to Yellowstone National Park biologist PJ White.

White is chief of wildlife and aquatic resources at Yellowstone and has researched all the major mammals in Greater Yellowstone, working to find solutions that help wildlife and humans coexist.

White is the author of more than 125 scientific papers and many popular books.

The Craighead Conservation Award was established in 2003 to honor the legacy of Frank and John Craighead, who were known for their pioneering research into grizzly bears.

Nominees should have significantly impacted wildlife conservation in the Greater Yellowstone region and demonstrated the dedicated spirit of the Craighead brothers through years of service in wildlife research, management, community involvement and policy.
