Within the desert areas of the Southwest there are a number of National Parks and Monuments. Three Monuments (Joshua Tree in California, Organ Pipe Cactus and Saguaro in Arizona) have been created primarily to save from exploitation and destruction outstanding areas of typical desert vegetation. Although the others have been established to protect and preserve geologic, historic, or archeologic values of national significance, they are all wildflower sanctuaries. In California, Death Valley National Monument is outstanding in its variety of desert flowers. Lake Mead National Recreation Area, of which Hoover Dam is the center, has exceptional displays of various forms of desert plants. A great variety of desert vegetation will be shown and, if desired, explained to the interested visitor, by National Park Service rangers at Chiricahua, Tonto, Montezuma Castle, Casa Grande, and Tumacacori National Monuments in Arizona. Of course the really great displays of desert botany and ecology are featured at Organ Pipe Cactus and Saguaro National Monuments.
In New Mexico, Chihuahuan Desert vegetation is particularly abundant at Carlsbad Caverns National Park. A number of desert forms, especially interesting because of the effect upon them of the ever-moving gypsum dunes, are found at White Sands National Monument, near Alamogordo. Another outstanding Chihuahuan Desert wildflower sanctuary is Big Bend National Park in southwestern Texas.
Photography is encouraged in all of the National Parks and Monuments. By asking a ranger, you will be able to learn where the various flower displays may be found, the best time of day to obtain good results, and other suggestions helpful in obtaining photographs of desert wildflowers at their very best.
Each year the following magazine and radio program present bulletins on moisture and other pertinent conditions in the desert, spotlight areas in which outstanding wildflower displays are developing, and advance suggestions relative to areas in which spectacular displays may be expected.

Many people think of a desert as an area of shifting sand dunes without vegetation except in areas where springs provide moisture. This is by no means true of our Southwestern deserts which are characterized by a rich and diversified plant cover. However, the majority of true desert plants are equipped by Nature to meet conditions of high temperatures and deficient and uncertain precipitation. The way in which desert plants, closely related to common species found growing under normal temperature and moisture conditions, have adapted themselves to meet the severe requirements of desert life is truly remarkable and forms an absorbing and fascinating study.
