Mont. Code § 87-5-701
The legislature finds that in order to protect Montana's native wildlife and plant species, livestock, horticultural, forestry, and agricultural production, and human health and safety, it is necessary to regulate the importation for introduction and the transplantation or introduction of wildlife in the state and to regulate the importation, transplantation, possession, and sale of exotic wildlife. Serious threats, known and unknown, from the introduction of wildlife and exotic wildlife into Montana necessitate the regulation of the importation for introduction and the transplantation or introduction of wildlife and regulation of the importation, transplantation, possession, and sale of exotic wildlife unless it can be shown that no harm will result from the importation, transplantation, possession, sale, or introduction. Any importation, transplantation, possession, sale, or introduction permitted must be conducted in a manner to ensure that wildlife or exotic wildlife can be controlled if harm arises from unforeseen effects.
