For wildlife in Oregon, the best way to stay alive is to make sure someone wants to kill you. If the state can make money selling a fishing license or a hunting tag for an animal, it goes to great lengths to keep populations healthy. Teams of biologists collar hundreds of mule deer with tracking devices that cost almost $1,000 each. State police fly planes over wilderness in the dead of night searching for poachers. In one recent four-year span, Oregon spent upwards of $37 million to improve habitat for mule deer. But for the Western pond turtle, a candidate for the endangered list, the state’s longest-running survey amounts to one man with some homemade gear in the back of his truck.
