Illinois Statutes Chapter 520. Wildlife § 5/2.2b. Imminent threat; nuisance permits

(a) It shall not be illegal for an owner or tenant of land, or his or her designated agent, to immediately take on his or her property a gray wolf, Canis lupus; American black bear, Ursus americanus; or cougar, Puma concolor if, at any time, the gray wolf, American black bear, or cougar is stalking or causing an imminent threat or there is a reasonable expectation that it causes an imminent threat of physical harm or death to a human, livestock, or domestic animals or harm to structures or other property on the owner's or tenant's land.

(b) The Department may grant a nuisance permit to the owner or tenant of land, or his or her designated agent, for the taking of a gray wolf, American black bear, or cougar that is causing a threat to an owner or tenant of land or his or her property that is not an immediate threat under subsection (a) of this Section.

(c) The Department shall adopt rules to implement this Section.
