In many areas in the Southwest deserts conditions favoring reestablishment of vegetation may only occur every four to seven years Hassell 1977, Cook et al. 1974. For this reason, successful revegetation of disturbed desert lands requires special methods to prolong or take advantage of favorable moisture periods. In addition to moisture stress, soil fertility and toxicity problems are also common on areas in need of revegetation. Several agencies deal successfully with these problems. Most notable in terms of large scale revegetation efforts, are the highway departments and mining companies. Smaller organizations specialize in various aspects of revegetation such as transplanting techniques or seeding operations. This paper reviews reclamation practices currently used by the Arizona Department of Transportation, and methods recommended for revegetation of surface mining operations. In addition, transplanting techniques used by the Desert Botanical Garden in Phoenix, Arizona are briefly discussed.
