Burning of savanna pastures is another important environmental impact of range utilization. This is said to release more CO2 than the burning of tropical forests.
Loss of wildlife genetic resources is an issue frequently associated with ranching. In the case of the rainforest regions of Latin America, where ranching is an important form of land use, this is probably not a major issue, given the large proportion of rainforest still untouched. In the Latin American savannas, human population density is very low and large national parks areas are maintained, again limiting the impact of livestock on wildlife biodiversity.
