Detailed explanation-1: -Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves.

Detailed explanation-2: -Continued overgrazing reduces inputs of soil organic matter because less plant biomass is available as litter, which in turn, reduces soil organic matter, nutrients, and biotic activity. This leads to deteriorated soil structure, which increases the potential for erosion and reduces water-holding capacity of soil.

Detailed explanation-3: -Overgrazing exceeds the carrying capacity of a pasture. However there may be other factors involved or contributing to apparent overgrazing such as climate change. Overgrazing often results in soil erosion, the destruction of vegetation, and other problems related to these processes.
