Feral burro have caused devastating damage to the vegetation and soil which has resulted in a deterioration of the entire biota. Wildlife numbers have declined where there is competition with burro for food, water, or space. The Department of Fish and Game made a burro survey in conjunction with bighorn investigations. There are an estimated 3,400 free-roaming wild burro In California. They are found in 7 of the 14 bighorn study areas and have caused problems in each of these areas.
