Here are a few common types of conservation buffers:

1. Contour grass strips are planted with perennial native grasses to reduce wind, protecting young plants and preventing the erosion of topsoil.

2. Field borders are strips planted along the edges of fields. These borders can be used as turn area for heavy machinery to avoid soil compaction.

3. Filter strips of grass or other native vegetation are designed to slow down and filter runoff before it enters nearby streams.

4. Riparian buffers of trees, shrubs, and grasses are planted alongside rivers and streams to intercept and filter pollutants in runoff. They also provide shade and habitat to a variety of aquatic creatures.

5. Grass waterways are strips of grass planted in areas of fields where water tends to be concentrated as it runs across the surface. The extra vegetation helps to prevent erosion, while also acting as a filter for pollutants.

6. Wetlands can be protected and preserved in areas between cropland and riparian corridors. Natural wetlands are populated with a wide range of water-loving plants and animals and act as barriers and filters for pollutants entering nearby waterways. They can also help to reduce the risk of downstream flooding.
