SB 3049 was passed by both houses this spring. It awaits the Governor's signature. It provides that an owner or tenant whose person or property is in imminent danger from a gray wolf, American black bear, or mountain lion may take the animal without restriction. An owner or tenant whose property is threatened, but not imminently threatened, by a gray wolf, American black bear, or mountain lion may apply to the Department of Natural Resources for a nuisance permit that shall allow the owner, tenant, or their designated agent to take the animal.
