St. Matthew Island Habitat Mapping

In June 2018 I had the opportunity to accompany the U.S. Fish and Wildlife Service (USFWS) as vegetation ecologist on a multi-disciplinary expedition to St. Matthew Island (SMI), a remote island located in the middle of the Bering Sea. Read about my experience on St. Matthew Island here: The Loneliest Place in Alaska
