Scrabble?! OVERGRAZING

Definitions of OVERGRAZING in various dictionaries:

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. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Cows are the main things that causes overgrazing and "overgrazing". However, "overgrazing" is a controversial concept, based on equilibrium system theory. It reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. It is caused by nomadic grazers in huge populations of travel herds, such as the American bison of the Great Plains, or migratory Wildebeests of the African savannas, or by holistic planned grazing.
