Grazing intensity refers to how much animals eat from the grass, affecting the health of the land. Some studies show that too much grazing can harm the plants, leading to overgrazing. Light grazing is often the best option. Heavy grazing can damage the land, especially when there are aggressive nonforage plants around. Undergrazing is less harmful but may miss chances to improve the plant mix. Grazing intensity impacts how well livestock grow and how profitable farming is in the long run.
