Hazing: The forced removal of wild bison from their chosen habitat. Hazing operations taking place under the Interagency Bison Management Plan (IBMP) are directed by the Montana Department of Livestock (DOL) in the state of Montana, and by Yellowstone Park rangers within Yellowstone National Park. Hazing is an ecologically destructive activity conducted with helicopters, snowmobiles, horses, motorcycles, all-terrain vehicles, and on foot. Hazing often results in injury, death, or disturbance to bison and other wild species.
Introgression: The transfer of genetic information from one species to another as a result of hybridization between them. Introgression describes the incorporation of alleles (a variant form of a gene) from one species into the gene pool of a second species.
Subspecies: A taxonomic category that ranks below species and is commonly indicative of geographical isolation. Organisms belonging to different subspecies are generally capable of interbreeding and producing fertile offspring, yet do not do so due to geographic isolation, sexual selection, or other factors.
