Assessment rationale/justification
There are currently about 700 mature bison of this subspecies in three free-ranging herds and about 250 semi-captive mature bison in Elk Island National Park. The largest free-ranging herd, in the Pink Mountain area of BC, is outside the historical range of this subspecies. The population in Prince Albert National Park is increasing by about 10% a year. The greatest problem facing these bison in Canada is the lack of habitat, due to conversion to agriculture and urbanization. Additional threats include domestic cattle disease and the risk of genetic pollution from escaped ranched bison, including some that may carry cattle genes. The total number of free-ranging and semi-captive mature bison of this subspecies is just under 1000, and there are fewer than 5 populations.; Il y a actuellement environ 700 bisons matures de cette sous-espèce dans trois hardes en liberté et environ 250 bisons adultes en semi captivité dans le parc national Elk Island. La plus grande harde en liberté, dans la région du mont Pink de la Colombie-Britannique, se trouve à l'extérieur de l'aire de répartition historique de cette sous espèce. La population dans le parc national Prince Albert augmente d'environ 10 p. 100 par an. Le plus grave problème de ces bisons au Canada est le manque d'habitat attribuable à la conversion des terres à des fins d'agriculture et d'urbanisation. Les menaces additionnelles comprennent les maladies des bovins d'élevage et le risque de pollution génétique des bisons d'élevage qui se sont échappés, y compris certains bisons qui peuvent être porteurs de gènes de bovin. Le nombre total de bisons matures de cette sous-espèce en liberté et en semi-captivité atteint un peu moins de 1 000 individus, et il y a moins de cinq populations.
