Erosion control and Filter Strips
Tallgrass species can be useful tools for creating buffer strips for riparian zones, as an alternative to trees or shrubs.
Tallgrass is very effective for filtration of sediment, and soil-bound nutrients, pesticides and bacteria, as well as for phosphorus management. They are generally effective for increasing shore/bank stability and creating wildlife habitat.
Narrow grassed buffers are very useful municipal next to intensively cropped areas, or in intensively grazed areas where livestock have been excluded and trees plantings aren’t suitable.
