X> X> Wildlife Friendly Erosion Control Wildlife entanglement in, and death from, plastic netting and other man-made plastic materials has been documented in birds (Johnson, 1990; Fuller-Perrine and Tobin, 1993), fish (Johnson, 1990), mammals (Derraik, 2002), and reptiles (Barton and Kinkead, 2005; Kapfer and Paloski, 2011). Yet the use of these materials continues in many cases,without consideration for wildlife impacts. Plastic netting is frequently used for erosion control during construction and landscape projects and can negatively impact terrestrial and aquatic wildlife populations as well as snag in maintenance machinery resulting in costly repairs and delays. However, wildlife friendly erosion control materials do exist, and are sold by several large erosion control material companies. Below are a few key considerations before starting a project. Know Your Options • Remember to consult with local natural resource authorities(DNR,USFWS,etc.)before starting a project. They can help you identify sensitive areas and rare species. • When erosion control is necessary, select products with biodegradable netting(natural fiber, biodegradable polyesters,etc.). • DO NOT use products that require UV-light to biodegrade (also called, "photodegradable").
