Wild mustangs in the United States live in ten Western states: Nevada, Wyoming, Utah, Oregon, California, Idaho, Arizona, Montana, North Dakota and New Mexico, as well as on islands off of the Atlantic coast. The habitat of wild mustangs include Western deserts, mountains and Eastern islands.
Wild mustangs often live in rocky terrain, where food and water is sparse. The Eastern island mustang population is unique, living in a habitat with marshland, dunes and tidal flats. Half of the wild mustangs in the United States are found in Nevada. The wild mustang population is controlled by the Bureau of Land Management. It is estimated that there are approximately 25,000 wild mustangs in the United States, with another 34,000 in holding facilities and long-term grassland pastures.
