Pronghorn are the last living members of an ancient lineage of distinctly North American animals. They are an iconic species easily spotted at American Prairie, despite remaining at historically low abundances.

Running at speeds of up to 60 miles per hour, they are also one of North America’s fastest land mammals. One herd has been shown to undertake the continent’s second longest land migration (of up to 500 miles round-trip). Because they cover so much ground, and therefore require large areas of intact prairie, pronghorn are a strong indicator species, meaning that their reaction to influences like human activity can help scientists assess how other species might also be affected.

Recent Research

Studying pronghorn migration on the Great Plains contributes to a body of research about long-distance wildlife migrations, which are threatened by development and habitat fragmentation. The annual pronghorn migration from northern Montana into southern Alberta and Saskatchewan and through American Prairie land is the second longest distance migration of any land animal in the Lower 48.

Next Steps

Our work to acquire habitat that glues together public lands, while also removing fences that act as stressful barriers, will help pronghorn populations grow and thrive.
