The future of the range management and livestock industry in Mexico is a matter of debate. The traditional use of land now goes to look for adjustments aimed to find new alternatives more efficient for obtaining energy in a sustainable way considering range management strategies that promote the multiple use of pasture in different ecosystems. Rangeland occupies approximately 51% of the earth's surface and supports different uncultivated vegetation types that can provide the requirements of life for native and domestic herbivores in a sustainable fashion. Range management is a synthesis discipline that draws from many different areas. Livestock cannot be permanently maintained on arid grazing lands, unless we use grazing systems that more closely approximate the type of grazing pressure applied by native game species. One basic consideration is that big-game herds feed selectively and keep moving and thus do not put sustained pressure on any one area. Since 2000, the Mexican legislation allows financial investment in land that can be used for the development of wildlife, as an alternative for the biodiversity conservation. Species such as white-tailed deer, bighorn sheep, mule deer, wild turkey, ocellated turkey, collared peccary, and others, have thrived in rangelands, allowing better use of land and generating new economies. The rangelands of Mexico include several types of vegetation such as deserts, grasslands, shrubs, forests, and riparian areas, where forage is produced only in favorable localized areas. All of these lands have a variety of uses, of which the support of livestock is only one. Many semi deserts and mountains have incomparable values as wilderness recreation lands and homes for rare forms of wildlife.
