Many visitors would be surprised to find out that 75 species of mammals inhabit the deserts and mountains of Big Bend National Park. Living in an area with high temperatures and low rainfall forces many animals to live extremely cautious lifestyles. Many leave their burrows only under cover of night. Others may forage during the cool of early the early morning. Larger mammals include whitetail and mule deer, coyote, mountain lion, and black bear. The snuffling you hear around your campsite at night may be a gray fox or a band of hungry javelina. Bats make up the largest portion of the park's mammal species. 20 different species have been observed here, including the endangered Mexican Long-nosed Bat, which has been found nowhere else in the entire United States.

The Harte Ranch section of the North Rosillos Mountains was added to Big Bend National Park in 1987. Property owners Houston H. Harte and Edward H. Harte donated the 67,000 acre ranch to the Texas Nature Conservancy in 1985 with the understanding that it would eventually become part of the park.
