The Chisos Mountains
If the Rio Grande is the linear oasis of the Big Bend country, then the Chisos Mountains are its green island in the desert sea. The combination of river and mountains draws a number of creatures not found elsewhere in desert areas, including several species of animals, birds, and plants that are quite rare, even unique, due to these mountains' isolation.

Average rainfall at the Basin, in the Chisos Mountains, is twice that at Rio Grande Village in the oasis along the river. When approaching the mountains from Green Gulch, you pass grasslands punctuated by century plants and sotol, but soon notice green leafy shrubs. Then the bushes get taller, with evergreen sumac, mountain mahogany, Texas madrone, and common beebrush. At an elevation of 4,500 feet the first tall trees begin to appear, and higher up in the drainage you will encounter well-forested areas.
