This from the Saskatchewan gov in regards to thier outlook, which is closely linked to our situation.
Quote:
Pronghorn antelope populations are on the rise across their western range. In
Saskatchewan, numbers have continually increased over the last three years.
Hunters should note this is a long distance trans-jurisdictional migratory species
and many of our pronghorn have migrated into the United States to escape one
of the coldest winters recorded in history on their range. The Ministry of
Environment has signed an agreement with Montana and Alberta to jointly
conduct research on this species through a large scale GPS/radio collaring
migration study. Preliminary results have indicated that many of the animals who
usually winter in southern Saskatchewan are now far south in Montana.
Migrations in excess of 600 kilometres have been recorded. This southward
winter migration is a normal part of pronghorn biology due to cold winter
conditions. Consequently the rate of spring green up will determine if and when
animals return. It can take the animals several months to begin migrating north if
they are pushed too far south by harsh winter conditions. The ministry will
conduct surveys in early summer to determine fall quotas.
