It is also the least known desert region of North America. With the exception of a few major population centers, such as Chihuahua City, El Paso, Albuquerque, Juarez, Durango, Torreon, Monclova, and Saltillo, the region is sparsely populated yet little of the desert is uninhabited. In the past, the sparse population of this vast region has been a blessing in preserving the desert?s biological and aesthetic resources. More recently, population expansion and resultant demands upon the resources have initiated changes that threaten every part of the Chihuahuan desert region. After the Mexican Revolution, the Mexican government embarked upon a widespread land reform policy. In the Chihuahuan desert this has meant, especially in recent years, a redistribution of population from the densely populated Central Valley of Mexico into the sparsely populated arid lands of northern Mexico. The resultant government-subsidized communal settlements, or ejidos, have markedly affected the delicate and easily disturbed desert ecosystem. While on the one hand the Mexican government must be commended for attempting to ameliorate the plight of the campesinos, concern must be voiced for the resource base which will sustain the ejidos now and in the future. Although the immediate concern is the short term solution of human problems, we, as biologists, educators, and politicians must realize that the long-term biological integrity of the resource base, the physical, chemical, and biological resources, is the prime issue.
