Overgrazing happens when plants are exposed to intensive grazing for extended periods of your time, or while not sufficient recovery periods. It may be caused by either livestock in poorly managed agricultural applications, or by overpopulations of native or non-native wild animals.Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one explanation for desertification and erosion. Overgrazing is additionally seen as a explanation for the unfold of invasive species of non-native plants and of weeds.
