Management Requirements: High capacity for population increase; management must be an on-going consideration (Perryman and Muchlinski 1987, but see Jenkins 1989). Study in western Arizona concluded that bighorn sheep population may be limited through resource competition with burro; advocated removal of burros from areas where they are sympatric with bighorn (Seegmiller and Ohmart 1981).
Regulated by Wild Horse and Burro Act of 1971. Most lands with are burros managed by BLM (see Boyles 1986).
Woodward and Sponenberg (1992) recommended that some desert populations be preserved as free-roaming herds for the purpose of maintaining an important store of genetic variation; an area near Marietta, Nevada, is being managed specifically for burros.
