Mangelsen and Wilkinson will be discussing the life of Jackson Hole Grizzly 399, the most famous mother bear in the world. They will also discuss the importance of grizzlies in the Greater Yellowstone Ecosystem, the role of the Endangered Species Act in recovering a grizzly population pushed to the brink, the remarkable family lineage of Grizzly 399, and how it almost ended as a result of her mauling a school teacher more than a decade ago. Most of all, they will be talking about why all of us need to consciously make more space for nature.
