This is because the animals will graze even on the slightest shoots of new growth. Overgrazing causes a chain reaction in the soil that decreases its health due to: Increased percentages of bare ground, leading to increased wind erosion and water runoff, along with higher soil temperatures that cause faster rates of evaporation. We cant avoid droughts and dry spells, but we can prevent overstocking and other factors that lead to overgrazing. But the confusion doesn't end there.
