A new method for controlling soil erosion

Science Daily: Soil erosion from rain and wind produces water quality issues in streams, rivers and lakes, degrades soil quality, and affects human health. Forest Concepts LLC, a small business in Auburn, WA, developed an environmentally-friendly solution called WoodStraw, an innovative erosion control material made from sliced strands of wood that is tailor-made for use on forests, highway projects, watersheds and other natural areas.

Previous erosion control methods, specifically the use of straw, were hampered by lack of stability under windy conditions, possible introduction of noxious weeds, chemical residue from pesticides and short-lived performance. WoodStraw is heavier than straw, making it less likely to be blown away when exposed to high winds.

The patented WoodStraw brand wood-based erosion control material is highly effective. An American Society of Agricultural and Biological Engineers study in California and Washington indicated application of the WoodStraw product reduced erosion by 98 percent compared to bare soil. In addition, a field experiment by the USDA Forest Service in Colorado noted WoodStraw outperformed all other mulch treatments.

WoodStraw is naturally weed-free and long-lasting. Since its introduction, WoodStraw has achieved regulatory approval by the Washington State Department of Transportation for use on transportation projects across the state and is recognized by the Washington Department of Ecology as an effective erosion control material.

Research and scientific progress continue to shed light on new benefits of WoodStraw. The product is currently being evaluated to see how it would perform for wind erosion and dust control on construction sites and for controlling blowing ash on burned areas such as rangelands….
