They aerate the soil with their hooves. This means that they loosen the soil when they walk on it. This allows more oxygen to enter the soil which helps grasses and plants to grow better. When cattle graze they shorten the length of grass, just as people do when they mow the lawn. This is very helpful in reducing the spread of wildfires since there is less material on the ground to burn.
Cattle also press grass seeds into the soil.
This is important because grass seed needs to be surrounded by soil in order to start growing. Cattle also provide manure for the soil which is a natural fertilizer for plants and grasses. Cattle can be found in all 100 counties in North Carolina. The most abundant area of the state for cattle is the Piedmont region. The least abundant is the Coast.
