Meet the Pronghorn
As seasons change, herds of pronghorn migrate hundreds of miles to escape deep snow cover that makes grazing impossible. They are creatures of habit and tend to return to migrate the same route year after year—and condition their young to do the same.
Protecting the Pronghorn
With pronghorn seasonally migrating more than 200 miles each way between their summer grounds in Canada and their wintering grounds in Montana, eliminating obstacles to their movement can be a matter of life and death.
Habitat fragmentation in the form of agricultural fences—particularly barbed ones—pose a dangerous threat because pronghorn can’t jump. Finding a route around these barriers wastes energy and calories that the animals need in order to survive the journey.
Fortunately for pronghorn, small changes can make a big difference. Switching out or modifying fences so that pronghorn can crawl under, rather than jump over, makes a huge difference.
The Nature Conservancy has already started modifying fences at our Matador Ranch in Montana, taking down miles of woven wire fencing and replacing it with wildlife-friendly fencing.
We’re also partnering with other organizations to study herds in Arizona to assess other threats to the species. This includes habitat viability analysis, movement
