“Controlled species” means live, exotic wildlife species, subspecies, or hybrid of species that may not be imported, possessed, sold, purchased or exchanged in Montana unless a person obtains written authorization from the department.

Written authorization to possess a species of exotic wildlife that has been classified as controlled may be requested by submitting an application. The application requires information on the exotic species requested, the intended purpose for possession, where the exotic species will be held, and the enclosures intended to contain the exotic species.
