About 90 percent of the burros are gray, with the remaining 10 percent black, brown, white pinto or piebald. Some burros possess the shoulder cross characteristic of the ancestral Nubian wild ass, and many have leg barring associated with the Somali wild ass. Adult burros average 48 inches in height and weigh about pounds.
During the summer months, the burros concentrate, generally within a mile or so of major water sources. During cooler months, the animals move into the mountains and scatter throughout the region.
There are four major vegetation communities found within the HMA. These are open hills covered with creosote bush; primary and secondary washes known for their paloverde and burro bush; and, secondary washes made up primarily of paloverde and creosote.
Summer temperatures are hot, with the thermometer sometimes rising above degrees. The area has days per year of degree temperatures. Wildlife: Wild burros share this habitat with desert bighorn sheep and desert mule deer. Other animals in the area include small mammals, desert tortoise, several species of rattle snake, a variety of bird such as the southwestern willow flycatcher, lizards and amphibians.
