Pronghorn antelope reach their northern-most distribution in Alberta and are known to conduct annual migrations averaging hundreds of kilometers often passing through narrow passages en-route to key seasonal ranges.
Migratory corridors are critically important in ensuring pronghorn remain at sustainable populations. Several documented accounts describe mass mortalities because of barriers to movement.
Fences in particular are known to create great difficulties for pronghorn as they are unwilling to jump over them. As lower strands are generally 12”-14” above ground, crawling under often results in serious scrapes that can significantly impact the antelope’s health as seen in the photograph on the next page. The migration corridor enhancement will remedy this situation by replacing lower barbed wire strands with smooth wire and at the same time raising them to a height easily navigable by the pronghorn.
