How It Works
Using ground covers, such as mulch or vegetation, are a great way to cover bare soil and to slow the amount of runoff. They can preserve valuable top soil, prevent sediment from being carried downstream, and reduce erosion potential.
Mulch is a useful protective top layer of material which can be organic like grass clippings, bark chips, or straw, or inorganic like glass, stones, or brick chips. Benefits include reduction of compaction, protection from erosion, conserving moisture and maintaining temperature of soil, and preventing unwanted species.
Plants provide a more long term solution for erosion. Roots knit together to hold soil in place to help stabilize slopes. Leaves, needles, and twigs reduce the impact of rain and runoff as well as adding an organic material for infiltration to help filter out pollutants.
