“Erosion”

Since the beginning of time man has disturbed natural vegetative cover to plant, build, and develop private property. When vegetation, crop residue, or natural cover is removed (trees, leaves/grass) soil becomes exposed to the elements. The weathering process now accelerates.

The thin covering of the earth can become mobilized by wind, rain, ice, and other forces.

Known as erosion, the displaced soil particles are washed into streets and creeks by a single rain drop that detaches particles and deposits them in our waterways.

This deposition alone negatively impacts the water quality and the foundation of our ecologic system found in streams and rivers. The spawning beds of wildlife habitats become compromised, weaking the development and proper progression of our overall food-chain.
