Buffers play a crucial role as a safety net for the environment.
 

BUFFERS

Properly installed buffers:

  • Contribute to productivity
  • Curb pollution
  • Preserve water quality
  • Provide wildlife habitat
  • Reduce flooding downstream

In rural areas, many farmers and ranchers work with USDA’s Natural Resources Conservation Service (NRCS) and other conservation partners.

When you hear the word “buffer,” what do you think of? Maybe it evokes a safety net, a filter, or an area of shrubs and trees. In the landscape context, that’s pretty much what it is.

A “buffer,” when referred to by a conservationist or a farmer, is a small strip of land of trees, shrubs and other plants. This strip provides protection from such things as wind or pollutants entering waterways and plays a crucial role as a safety net for the environment.

Conservation buffers trap sediment, fertilizers, pesticides, pathogens and heavy metals. To do this, buffers act like natural filters, removing nutrients or sediment that water runs off the field, keeping them from entering waterways.

If properly used, buffers remove more than 50 percent of nutrients and pesticides, 60 percent of certain pathogens and 75 percent of sediment. Not bad for a strip of trees and shrubs, right?

In addition to trapping pollutants, buffers slow water runoff and increase the amount of water that enters the ground, recharging our aquifers and protecting communities downstream from flooding.

During the winter buffers help trap snow and cut down on soil erosion in areas with strong winds. They also can protect livestock and wildlife from harsh weather, shield buildings from wind damage and reduce noise and odor coming from a farm.

Buffers provide numerous benefits for local wildlife. They are provide food and shelter for many wildlife species like quail, rabbit and other fun-to-watch species and can serve as connecting corridors that enable wildlife to move safely from one habitat area to another.

A conservation buffer’s trees and shrubs shade streams and cool the water, making the water a better home for plants and critters. Without trees and shade, streams become warmer, lowering populations of aquatic species. Also, buffer trees and shrubs stabilize streams by holding the earth in place with their roots. In addition to their vital services, buffers simply beautify the landscape, enhancing the natural aesthetics of a farm or ranch.

USDA’s Natural Resources Conservation Service (NRCS) helps private landowners create buffers on their land, along waterways and between fields. If used as part of a comprehensive conservation system, buffers make good use of areas that are not ideal for growing crops or other uses.

But buffers aren’t just for rural areas – they’re helpful in suburbs and cities alike. Buffers in these areas can yield the same benefits, especially along waterways and other ecologically sensitive areas.

Whether you live in the country or a big city, buffers will help improve the environment near you. Equip your property with buffers if you can, and encourage your local officials to do the same, protecting streams and other key landscapes.

Stop by your local NRCS office, and learn more about how buffers can help your land and how to get started.
