Big Bend National Park is located at the northern end of the Chihuahuan desert. Since most of the Chihuahuan desert is located in Mexico, Big Bend represents the largest protected portion of the Chihuahuan desert in the United States.
In Big Bend you will find the desert to be the largest ecosystem in the park. Typical animals found in the desert are javelinas, roadrunners, jackrabbits, millipedes, and mule deer. The most familiar desert plants in the Chihuahuan desert are lechuguilla, sotol, numerous species of cactus, mesquite, and yuccas.
The Chihuahuan desert is the wettest of the four North American deserts, though we rarely receive more than 10 inches of rainfall. The rainy season in the desert is usually from mid-July through late September. Though we call this the rainy season, there are places in this desert environment that may not receive a drop.

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.
