Distribution of suitable habitat in winter and summer for plains bison (Bison bison bison) in the Pink Mountain Region of British Columbia

Based on the habitat suitability model conducted, there appears to be significant habitat of sufficient quality to support a population of plains bison year-round in the Halfway River drainage. Areas with acceptable habitat were predominately in the river bottoms or valleys and the far eastern section of the study area. In the summer, approximately 60% of the area was categorized as a habitat suitability index of at least six.

In winters with maximum snow coverage, only 17% was similarly categorized. Despite this, it is my impression that the area acceptable as habitat is sufficient for a considerable population of bison. Extending the area under study and creating estimates of forage production could lead to a more detailed assessment of carrying capacity for bison in the region, leading to improved management of this iconic species.
