Chadwick is a past officer and current member of the board of The Vital Ground Foundation, and chairman of that organization's Lands Committee, responsible for choosing acquisition properties as part of Vital Ground's One Landscape wildlife corridor system. He is also a director of the Gobi Bear Fund, part of the Gobi Bear Initiative, which attempts to restore the world's least known and most endangered population of grizzly bears. Since 2013 he has served on the advisory board of the Liz Claiborne Art Ortenberg Foundation, a New York-based non-profit that supports wildlife research and collaborative, community-based conservation projects around the world.

In 2006, Chadwick began what would become a five-year participation in the Glacier Wolverine Project, to follow a small set of wolverines as they traveled over their extensive habitat centered on and around Glacier National Park (U.S.). This study was the subject of Chadwick's book, The Wolverine Way, and the PBS/Nature documentary Wolverine: Chasing the Phantom. Chadwick played a major on-screen role in the Nature documentary. The Glacier Wolverine Project was conducted by the U.S. Forest Service, Rocky Mountain Research Station, Missoula, Montana, under the leadership of principal investigator, Jeffrey Copeland.

Chadwick's affiliation with National Geographic spans more than thirty-five years and more than fifty articles from the first in 1977 up to an assignment in 2019 for an article on wolverines. Other publications which have featured his work include: Defenders of Wildlife, Audubon, The Huffington Post, Backpacker, TV Guide, The Smithsonian Magazine, Sports Illustrated, Reader's Digest, and Outside. He has appeared in two PBS documentaries: Night of the Grizzlies (2010) and Wolverine: Chasing the Phantom (2010).
