Résumé
I studied selected wildlife on an undisturbed mesquite range, a mesquite-free range, and a mesquite range with clearings on the Santa Rita Experimental Range. I visually censused six mammals and four birds monthly from September 1976 to June 1978. I visually cen sused six lizards monthly from April to September 1977 and from April to June 1978. I counted pellets and scats every three months starting December 1976. I counted calls of doves and quail every two weeks from April to June, 1977 and 1978. The mesquite with clearings contained significantly more black-tailed jackrabbits, antelope, jackrabbits, gambel’s quail, western whiptails, and all reptiles sighted than the mesquite-free range. The undisturbed mesquite contained significantly more black tailed and antelope jackrabbits, zebra-tailed lizards, western whip- tails, and all reptiles sighted than the mesquite-free range. I counted significantly more lagomorph pellets on the mesquite areas than the mesquite-free range. I heard significantly more calls in the mesquite ranges. Creating clearings in mesquite is not detrimental to the selected wildlife I studied. Totally clearing mesquite from ranges is harmful to wildlife in some instance.
