Ecological Impacts
Overgrazing typically increases soil erosion. Reduction in soil depth, soil organic matter and soil fertility impair the land's future natural and agricultural productivity. Soil fertility can sometimes be mitigated by applying the appropriate lime and organic fertilizers. However, the loss of soil depth and organic matter takes centuries to correct. Their loss is critical in determining the soil's water-holding capacity and how well pasture plants do during dry weather.
Native plant grass species, both individual bunch grasses and in grasslands, are especially vulnerable.

Famous quotes containing the words ecological and/or impacts:
“The hatred of the youth culture for adult society is not a disinterested judgment but a terror-ridden refusal to be hooked into the, if you will, ecological chain of breathing, growing, and dying. It is the demand, in other words, to remain children.”
—Midge Decter (b. 1927)
“We are no longer in a state of growth; we are in a state of excess. We are living in a society of excrescence.... The boil is growing out of control, recklessly at cross purposes with itself, its impacts multiplying as the causes disintegrate.”
—Jean Baudrillard (b. 1929)
