Recreational snow-mobilers  are the biggest cause of the decline if the caribou in the mountains of BC.

In the winter the highways in BC are very busy with vehicles hauling snowmobiles to their favorite beautiful pristine area.. Most snow-mobilers travel in small groups. Their machines create a compacted trail throughout large areas. Although wolves have huge snow shoe like paws, this compacted trail gives them a huge advantage but does nothing for the heavier caribou.

Contrary to the old Disney propaganda,  wolves are killing machines.  When they come across a group of caribou, elk, or moose, they will kill the whole group. Very frequently the wolves will only feed on the dead animals until the meat is frozen.  They will then go on to kill another group. Some dead animals are left intact.

In many mountain areas where the caribou live there are no resource industries or roads, just lots of winter. snow mobilers.
