Quick Answer: What Are The Causes And Effects Of Overgrazing?

What are the effects of overgrazing?

Overgrazing leads to soil compaction, decreased water retention, increased salinity, and loss of some nutrients, particularly nitrogen.

Our results also suggest a strong influence of overgrazing and its associated changes in vegetation condition on the soil ability to buffer water stress during the dry season..

How does overgrazing affect animals?

“During overgrazing, animals reduce plant leaf areas, decreasing plants’ ability to intercept sunlight and grow new leaf material. This reduction in turn slows down plant regrowth, drains energy reserves, and if left unchecked, can lead to eventual plant death.
