Jackson, Wyo. • The current superintendent of Yellowstone National Park and two of his predecessors say the park will always need advocates.
Former Yellowstone superintendents Bob Barbee and Mike Finley joined current Superintendent Dan Wenk for a fireside chat on Saturday with several hundred members of the Greater Yellowstone Coalition.
The Jackson Hole News & Guide reports (http://bit.ly/1aiwCJl ) the three said that, although the park is healthy in many respects, there are looming threats to its integrity.
Among the problems are bison herds that find natural wintering grounds outside Yellowstone and decimation of the native cutthroat trout population by exotic lake trout.
