David Mattson
David Mattson is a Research Wildlife Biologist with the U.S.
Geological Survey stationed at its’ Colorado Plateau Field
Station in Flagstaff, Arizona. David has studied grizzly bears for
the last 21 years, focusing on the conservation and behavioral
ecology of bears in the Yellowstone ecosystem of Wyoming, Montana,
and Idaho in the U.S.A. He spent 14 years intensively observing
grizzly bear foraging behavior and diet as well as ecological
relations of foods the bears ate. These studies revealed details
about a broad spectrum of bear behaviors, including their bedding,
use of rub trees, consumption of dirt and earthworms, exploitation
of red squirrels, pocket gophers, and meadow mice, and predation
on elk, moose, and trout. More recently, Dr. Mattson has focused
on conservation issues and broad-scale evaluations of habitat
conditions. These studies have broached not only the details of
human-grizzly bear interactions, but also the social, political,
and organizational dynamics that shape the policies and practices
of carnivore conservation programs. His work has been featured in
the journal Science and has been widely presented,
including papers in Ecology, Conservation Biology, Biological
Conservation, The Journal of Wildlife Management, and
the Journal of Mammalogy, and invited talks at the
Smithsonian, American Museum of Natural History, the American
Institute of Biological Sciences, and the International Conference
on Bear Research and Management.
