How Trees Prevent Erosion in Hickory, NC: A Brief Guide

Our environment couldn’t survive without trees for countless reasons, one being erosion. Learning how trees prevent erosion can help you understand why you need to protect the plants in your yard so that you can guard your property and local ecosystem from damage. 

Below, Limbwalkers Tree & Crane Service, the best tree service specialists in Hickory, NC, discusses how tree root systems and soil erosion control go hand-in-hand.

What Is Soil Erosion?

The earth has distinct horizontal layers of soil, from topsoil all the way down to the bedrock layer. Soil erosion is the process of topsoil wearing away or, as often happens, displacing.

Severe erosion can destroy entire beaches, river banks, canals, and more. That’s why environmentalists seek natural erosion control methods–like beautiful trees.

Why Does Soil Erosion Happen?

The following factors can cause erosion in the soil without trees:

  • Heavy rainfall.
  • Melting ice.
  • Powerful rivers and waterways.
  • Landslides.
  • Strong winds.
  • Deforestation.
  • Construction and urban development.

These factors have one theme in common: no trees. After all, reforestation for slope stabilization is a common tactic for a reason.

How Do Trees Prevent Soil Erosion?

If you want to understand the impact of deforestation on soil erosion, you first must learn why tree planting prevents erosion. How do trees prevent soil erosion exactly? Here are four ways:

Root Binding and Soil Compaction Prevention

Intricate, wide root systems span two to four times the diameter of the tree canopy. These roots latch onto the nearby soil for water and nutrients. In locking themselves into place, trees also hold the soil in place.

While root binding may be a more obvious answer to how trees prevent erosion, we cannot forget the soil compaction benefit. Without trees, soil becomes tightly compacted over time, which prevents water absorption and increases runoff. Intruding roots disturb pockets of soil to ensure that water drains well.

Proper Water Drainage

Trees aid in water drainage in many other ways, too. Aside from water compaction prevention, tree canopies also mitigate how much water reaches the topsoil at once. A dense forest offers a safer, more flood-proof environment, which can prevent erosion. 

Additionally, forest floors have foliage, such as leaves, twigs, and decaying materials. These layers act as a shield, channeling water through a mesh net before the soil absorbs it. The ground doesn’t receive rainfall all at once that way. 

Transpiration

Transpiration refers to the way trees absorb water with their roots. From there, they move it through the tree’s trunk, stems, and leaves. 

Through this process, trees remove excess water from the soil. In turn, this prevents runoff, heavy soil slides, and compaction. 

Wind Protection

Did you know that trees act as key windbreakers? Erosion from high winds is a thing of the past with windbreak trees for erosion prevention in place. 

Planting tree windbreakers close together is best.
