Riparian buffers, which are trees, shrubs or other vegetation along a stream or waterway, are an important tool to improve the health of the Chesapeake Bay ecosystem. The plants help filter pollutants that would otherwise enter the stream and ultimately the Bay. The buffers reduce land erosion and sediment delivery to streams or sedimentation, which can be harmful to stream health. Although erosion and sedimentation are natural processes, inappropriate land-use can accelerate their impact and cause sediment pollution.
Watch as CBF Field Educator Liz Yocom details how riparian buffers can improve stream health and identifies several macroinvertebrates that can be found in streams.
