ABSTRACT:
An erosion barrier implementing the invention is a filter berm advantageously comprising a biodegradable “sock” filled with a biodegradable material, e.g., using conventional blower techniques. The sock is composed of materials, such as burlap, that naturally rot and decompose. Thus, when the sock decays, it merges into the surrounding soil and thus leaves no trace. Preferably, the biodegradable material comprises compost that is pre-seeded to allow desired vegetation to grow from the compost into the underlying soil. In this manner, the vegetation anchors the berm and prevents it from eroding, even when its exterior sock is fully decomposed. In an exemplary embodiment, the sock may be constructed with larger holes on its bottom so as to allow the material in the berm to effectively bind and adhere to the soil beneath.
