The chemical and physical responses of desert shrubs and grasses to defoliation

"Major objectives of project: 1) to determine the chemical and physiological responses of desert browse and grass to forage removal at 3 different intensities and during 4 different periods during winter, spring and summer; and 2) to determine the recovery of desert browse and grass after being subjected to 3 years of treatment involving 3 intensities of forage removal during 4 different periods during the winter and spring in a previous study"--Page 1.
