Top: The Northern Elk Herd in Yellowstone, pictured here on the move, has been growing and elk have headed deeper into Paradise Valley in winter.  Above: In previous years, cow elk would be heading to the mountains with their calves. But ever increasingly, they and their young are remaining on the bottomlands and lower slopes of Paradise Valley, putting them on a brucellosis collision course with domestic livestock. What's the solution? PERC says it is to use incentives that make elk and asset instead of a liability. Photos courtesy Jacob W. Frank/NPS (top) and Implement Productions.
