How can tree planting can prevent soil erosion?

Question

Josephine Allen · Accepted Answer

Trees reduce the chances of rain harming soil. The roots of trees create multiple channels that can hold soil in place. The foliage atop trees prevents harsh winds and rains from attacking soil.

Vegetation, including trees, holds soil in place.

Vegetation, including trees, holds soil in place and shelters it from wind and water, preventing soil erosion.

The roots from trees and other plants stabilize the soil and hold it in place. Vegetation also lessens the impact which precipitation hits the ground and shelters the soil from wind erosion as well.

While smaller precipitation events may not greatly affect the soil, large events where the soil cannot absorb the precipitation quickly enough results in soil being washed away. Bare soil is far more likely to be negatively affected than soil that is sheltered by plants and held in place by their roots.

The same is true for wind. Bare soil is much more likely to shift and be transported than soil that is held in place by plant roots and sheltered.

undefined Tree planting can prevent soil erosion by stabilizing the soil with their root systems, reducing the impact of rainfall on the soil surface, and promoting the formation of soil structure through organic matter deposition.
