Animal: Pronghorn
Taxonomic Name: Antilocapra americana
Conservation Status: Least Concern (IUCN Red List)
Wild Range: Grasslands, steppes, foothills, and deserts in North America
Diet: Browse, flowering plants, grasses, and cacti
Longevity in the wild: 10 years
Size: 82–104 cm (height at the shoulder)
Weight: 40–65 kg
Fun Fact: Reaching speeds up to 100 km/h, the pronghorn is the fastest land mammal in North America. Their ability to run at this speed likely evolved in response to a now-extinct predator from the last Ice Age, the North American cheetah.
APZ Location: Open Range
Conservation Story: Like other large grassland mammals, pronghorns were overhunted during the 19th century and experienced severe population declines until protection began in the mid-1900s. While populations are currently stable, Pronghorns are vulnerable to human-made barriers, such as fences and roads, that break up the continuous expanses of grassland they rely on.
