Definitions for "Filter strip"
A vegetated area of land separating a water body from forest management activities.
A gently sloping grass strip planted between the livestock yard and drainage ways to streams and managed to filter runoff from the livestock yard. Influent waste is distributed uniformly across the high end of the strip and allowed to flow through the strip. Nutrients and suspended material remaining in the runoff water are filtered through the grass, absorbed by the soil and ultimately taken up by the plants. Filter strips must be designed and sized to match the characteristics of the livestock yard. A typical practice is to make the filter strip area about equal to the livestock yard area.
