Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. [1] It can be caused by either livestock in poorly managed agricultural applications, game reserves , or nature reserves .
Overgrazing can occur in both terrestrial and marine environments and can alter vegetation as well as the composition of vegetation. Population densities and the composition of fauna can also be negatively impacted on. [3] Additionally, permanent ecological damage can be caused by overgrazing before maximum carrying capacity has been reached. [3]
Overgrazing may cause erosion, habitat destruction, soil compaction, or reduced biodiversity (species richness). [13] Rambo and Faeth found that the use of vertebrates for grazing of an area increased the species richness of plants by decreasing the abundance of dominant species and increasing the richness of rarer species.

The causes for land degradation are numerous and complex. [1] Human activities are often the main cause, such as unsustainable land management practices.
