Join Sacajawea Audubon on October 10th for a a talk on the natural history of Yellowstone’s grizzly bears with Dr. David Mattson. Dr. Mattson will tell us what makes grizzly bears unique; how and when they got to North America and the Yellowstone region, and the following process of extirpation during 1800-1950; what makes Yellowstone's grizzlies unique, especially when it comes to diet and foods; and, in light of that, why Yellowstone's grizzly bears are severely threatened by on- going losses of food and other environmental deterioration.
Dr. Mattson has more than 35 years of professional training and experience focusing on the ecology and management of grizzly bears and mountain lions as well as the role of science in natural resources policy. He holds degrees in Forest Resource Management and Forest Ecology, and a doctorate in Wildlife Resource Management.
Prior to his retirement in 2013, Dr. Mattson was Research Wildlife Biologist, Leader of the Colorado Plateau Research Station, and Western Field Director of the MIT-USGS Science Impact Collaborative, all with US Geological Survey. He is currently Lecturer and Senior Visiting Scientist at Yale School of Forestry & Environmental Studies, Research Associate with the Northern Rockies Conservation Cooperative, and Adjunct Faculty with Northern Arizona University.
Dr. Mattson’s research on the habitat and behavior of Yellowstone’s grizzly bears dates back to 1979. From 1984-1993, he held primary responsibility for investigating grizzly bear diet, habitat use, and relationships with humans as a member of the Interagency Grizzly Bear Study Team. He has authored numerous publications on the ecology and demography of Yellowstone’s grizzly bear population.
