The Yellowstone Ecosystem Subcommittee of the Interagency Grizzly Bear Committee will be in Jackson this week to hold its spring meeting which is to include reports on the estimation of the Greater Yellowstone Ecosystem grizzly bear population and issues relating to future management. The Yellowstone ecosystem grizzly bear recovery area includes all of Yellowstone & Grand Teton National Parks, as well as portions of northwestern Wyoming, eastern Idaho, and southwestern Montana. Recovery Leader Chris Servheen of the US Fish and Wildlife Service will discuss new demographic measuring criteria and the current public comment process. Frank van Manen, leader of the USGS Interagency Grizzly Bear Study Team will provide updates on the ongoing GYE grizzly bear foods synthesis project and the mark-resight population size estimator work. IGBC Spokesman Gregg Losinski says the meeting will also feature the premiere of a film produced by the Wyoming Game and Fish Dept. called Yellowstone Grizzly Bears: A Success Story. Losinski says the public is welcome to attend any of the sessions which begin Wednesday at the Wort Hotel, and time for public comments will be provided.
