Four Environmental Benefits of Erosion Control:
1. Reducing Runoff Velocity
When sites use erosion control blankets, the vegetative layers absorb the energy of the rain as it hits them. By doing so, they reduce the velocity of the subsequent runoff. The slower, less forceful runoff carries away only a small amount of sediment.
2. Maintaining Soil Integrity
RECPs like erosion control blankets also act as filters to trap sediments and keep them from entering runoff streams. The blankets thus help maintain the integrity and absorptive capacity of the soil. Topsoil, which is the most likely part of the ground to erode, contains the most nutrients, so preserving soil integrity also means maintaining fertile land for vegetation growth.
3. Controlling Pollutants
Often, when sediments wash away in runoff, they carry chemical residues with them. The soil from a construction site, for instance, might contain paint, solvent or adhesive residues. These pollutants can diminish the water quality, affix themselves to the soil in other areas, stunt vegetation and poison local wildlife. Using erosion control blankets decreases these harmful effects.
4. Maintaining Habitats and Biodiversity
As erosion sweeps more and more sediment away, it can erode significant chunks of land over time, causing habitat loss for the wildlife species that live there. When these species die-off or must leave in search of new homes, the area’s biodiversity diminishes. Using erosion control blankets keeps soil in place to preserve habitats and help various species flourish.
