Under the Wire

The ongoing pronghorn projects focus on one of the most specialized and representative mammals in the grasslands. Pronghorn are long-distance sprinters, running up to 95 km/h making it the fastest land animal in North America. Because it evolved on the wide-open plains, it never developed an ability to jump.

Pronghorn have been migrating across North America since there was a continent to migrate across but in the last few hundred years, barbed wire fences used to keep our livestock from roaming have criss-crossed the pronghorn’s entire range and have impacted its daily, seasonal, and migration routes.

Unable to jump fences, they are forced to attempt to crawl under the lowest barbed wire set a mere 30 centimetres off the ground. The barbs rip their fur and skin off leaving them exposed to Alberta’s winter, or they can get caught up in the wires, leaving them defenseless against predators or to die from exhaustion.

ACA, along with our partners, has spent close to 10 years coming up with different solutions with no signs of slowing down until pronghorn can travel unimpeded once again.

When deciding what fencing enhancements will benefit pronghorn, we also need to consider all the other grassland species. So far, ACA has tested three modifications and we plan to continue trying new ideas to build upon our previous results for evidence-based wildlife-friendly fencing. Discussions with landowners are an important part of the process. For any modification to be successful, landowners have to be comfortable that any modification they implement will still contain their livestock while allowing passage by pronghorn.

For the last eight years, ACA has assisted Alberta Fish & Game Association with modifying fences to pronghorn standards. Our involvement in the project includes manpower and a grant through the National Fish and Wildlife Foundation. So far, 350 km of fencing within the grasslands of southern Alberta has been retrofitted. The modification affects the bottom wire on a barbed wire fence, raising it from 30 to 45 centimetres and replacing it with a smooth wire.

In year two of three, this project deals with the Pronghorn Xing project. Pronghorn Xing is a citizen science program developed by Miistakis Institute—in partnership with Alberta Conservation Association, Alberta Environment and Parks, Alberta Transportation, Saskatchewan Ministry of Environment, and Saskatchewan Government Insurance—to learn where the pronghorn are crossing the highway. Information on wildlife sightings are gathered through a website mapping tool or a free smartphone app and will lead to the development of tools to reduce wildlife-vehicle collisions.

In its second of two years, the Pronghorn as a Grassland Indicator Project focuses on assessing if pronghorn are a suitable candidate species to represent grassland wildlife in conservation planning. In partnership with the University of Montana, The Nature Conservancy, and Sage Grouse Initiative, and supported by a grant from the National Fish and Wildlife Foundation, we will finalize our analysis and manuscripts assessing the overlap in use of habitat for a suite of grassland obligates.
