Résumé
Bird, rodent, lagamorph, and coyote populations were monitored from June 1981 to May 1982 in 12 retired agricultural fields representing 4 serai stages, and in 4 climax-community sites in southcentral Arizona. Fields with tall, dense stands of annual vegetation had wintering granivorous birds, cottontail rabbits, and hispid cotton rats. Fields with short annual grasses and forbs had ground foraging birds, but few rodents. The presence of ruderal shrubs did not increase avian abundance, but two of three fields with ruderal shrubs had many rodents. Climax community shrubs and spinescent trees attracted forage-gleaning and aerial-hawking insectivorous birds. Woodrats, desert pocket mice, and round-tailed ground squirrels were most abundant in sites with climax community shrubs. Management practices that promote plant growth and succession will benifit wildlife populations on retired farmland.
