In March, the zoo and its conservation partners collected 47 wild pygmy rabbits from Utah and Nevada and released most of them at Sagebrush Flat. Conservation officials hope the wild rabbits will breed with rabbits raised at the zoo. This cross-breeding will strengthen the endangered Columbia Basin pygmy rabbit stock and increase its chance of a successful recovery.
