Factors involved in the invasion of woody shrubs and restoration of the range in the desert grassland association of the Southwest
Abstract
Scope and Method of Study: Some of the literature concerning factors that have been associated with the deterioration, the invasion of woody shrubs, and possible restoration of range lands in the desert grassland association of the Southwest has been reviewed. Findings and Conclusions: Overgrazing, effects of rabbits and rodents, fire or cessation of fire, competition, and change in climate appear to be the major factors involved in the invasion and deterioration of range lands in the desert grassland association of the Southwest, Restoration, in view of cost of implementing presently known to control techniques and lack of knowledge of lasting effects, does not seem to be economically feasible except, perhaps, on a moderate, graduate scale.
