Looming Issue with Plastic Mesh/Netting in Erosion Control Products Plastic mesh netting is a common material in erosion control prod ucts. It is utilized to hold loose fibrous materials in place AEG straw) until vegetation is established. These products have been used extensively and are successful for reducing sail erosion, benefit -Ling both sail health and water quality_ Unfortunately there is a negative side of this component It is increasingly being documented that it poses dangers to reptiles, amphibians, and mowing machinery. Potential Problems: a Plastic netting lays on the surface long after other components have decomposed_ ▪ Plastic mesh netting can result in entanglement and death of a variety of reptiles (snakes, frogs, toads, and turdes)- f}uoklings have also been documented entangled in the netting. ▪ Road maintenance machinery can snag the plastic mesh and pull up long lengths into machinery, thus binding up machinery and causing damage andeor loss of time cleaning it out Suggested Alternatives: + Do not use in known locations of reptiles or amphibians that are listed as Threatened or Endangered species. ▪ limit use where reptiles are likely (near wetlands, lakes. watercourses. or rack outcrops). + Use rapidly degradable material in all components of erosion control blanket, netting or biology (fiber rolls) that are to be left on site as pa rtcif final stabilization. + Use types with smaller mesh size (smaller that W) or use types with non -welded netting. yW. .. r reas near wetlands, lakes, watercourses are molt outcrops are iikefy habitat for rerniles and amphibians and may not be suM..able for plastic mesh erosion control materials.
