• Bouteloua eludens: Elusive Indeed, But Not Rare

      Reeder, John R.; Reeder, Charlotte G.; University of Arizona (University of Arizona (Tucson, AZ), 1990)
      Although considered to be rare and represented by only a few collections, the most recent in 1960, Bouteloua eludens Griffiths is shown to be relatively common in southern Arizona and in northern Sonora, Mexico. It has been known in Arizona only from the Santa Catalina and Santa Rita Mountains in Pima County, a few areas along Ruby Road in Santa Cruz County, and one collection from the northern end of the Whetstones in Cochise County. Recent field work has demonstrated that this species is by no means rare, but it is elusive. We found it, often in abundance, in all previously known sites. New localities for Bouteloua eludens are: Empire, Rincon, and Sierrita Mountains of Pima County; Dragoon, Mule, Swisshelm, south end of Whetstone Mountains, Tombstone Hills, and Guadalupe Canyon of Cochise County; the Canelo Hills, Mustang and Patagonia Mountains of Santa Cruz County.

      Nineteen forage species used by Desert Mule Deer (Odocoileus hemionus crooki) in the Picacho Mountains, Arizona were collected bimonthly in 1983 and analyzed for dry matter, protein fiber, lignin, ether extract, ash, cellulose, cell solubles, and hemicellulose. Results of the analyses are presented as a reference source for wildlife biologists, range managers, and others working with desert ecosystems.
