IMPORTANT WILDLIFE AREAS
REDROCK WILDERNESS:
Southern Utah's redrock country contains the largest acreage of unprotected wilderness in the western United States. More than two dozen endangered or sensitive animal species, including the Gila monster, whose saliva is the source of what may prove to be an important new drug for treating diabetes, and the desert tortoise, live in this fantastic terrain of wildly twisted rock shapes and invaluable indigenous cultural sites.
CHIHUAHAN DESERT:
A thumb of this great desert extends north of the Mexican border into southern Arizona, New Mexico and Texas. Its dry, cactus-spotted landscape is prime roadrunner territory. The shrubby terrain also supports pronghorn antelope, mule deer and jackrabbits, while hawks, eagles, bobcats, and of course wily coyotes like the clear sightlines to their prey. In Big Bend National Park, which hugs the Rio Grande in West Texas, more than 450 species of birds have been identified.
TEXAS HILL COUNTRY:
This dollop of grassland northwest of San Antonio features a mosaic of open woodlands and tall grasses, rocky hills and deep canyons, clear lakes, spring-fed streams and limestone caves. Endangered birds like the golden-cheeked warbler and black-capped vireo nest in the woodlands, while bats roost in the caves below. Springs support the Texas blind and San Marcos salamanders, both endangered.
