Welcome to the World of Pronghorn
Pronghorn
Antilocapra americana
Also known as: American antelope
Average lifespan: 10–12 years in the wild
Primary habitat: Grasslands, plains, and desert shrublands
Geographic range: Western and central North America
Overview
The pronghorn is the fastest land mammal in North America and one of the fastest on Earth. Often mistaken for an antelope, it is actually a unique species found nowhere else in the world. Its speed and endurance evolved to escape ancient predators that no longer exist.

Conservation
The pronghorn plays an important role in North American grassland ecosystems by shaping plant communities through grazing and serving as prey for native predators. Although not currently endangered, pronghorn populations are threatened by habitat fragmentation, fencing that blocks migration routes, road development, and loss of open prairie. Conservation efforts focus on protecting grasslands, restoring migration corridors, wildlife-friendly fencing, and coordinated land management to ensure pronghorn can continue their long-distance movements and thrive on the open plains.
