Building Buffers

The Buffer zone: The strip of land and water at the water's edge. A properly cared for buffer acts like a sponge filtering pollutants and keeps water clean and clear.

Tips for a healthier Maine

Quick Tips

  • Stop mowing to the edge. Let the grass grow. It will help filter pollutants.
  • Preserve. Keep what's growing naturally in your buffer zone.
  • Don't bare all. Plant or mulch bare soil.
  • Do not rake up the “DUFF” - nature’s mulch (twigs, needles & leaves that fall between the plants in the buffer).
  • Mix it up. Plant a mix of species of different heights including shrubs and trees. Make sure they're suited to your soil and sunlight conditions. Try native plants.
  • Forgo the fertilizer frenzy. Keeping lakes clean means little to no fertilizer use. If you must: use small amounts of organic matter or slow or timed release fertilizers, and unless a soil test indicates a need, always say NO to fertilizers contining phosphorus. For phosporous free fertilizer sources go to http://www.maine.gov/dep/land/watershed/fert/phospage.html.
  • The wider the better. Bigger is better when it comes to building a buffer, but any buffer is better than no buffer at all!
  • What about my view? Let's put it this way, if you don't buffer and your neighbors don't buffer, then you're ruining your view anyway. Planting a buffer protects water, but it also protects your property value. Try groundcovers and low growing trees and shrubs.
  • Plan your path. Paths should be winding to interrupt the flow of rainwater. Cover bare soil with bark mulch or crushed stone.
  • Shrink surfaces. Minimize hard surfaces like pavement, patios, decks, roofs, compacted gravel and compacted lawns. Direct runoff from these surfaces into a buffer.
  • Stop soil from taking a swim. Mulch exposed soil on slopes or use erosion control netting. Water new plantings carefully, use a silt fence or hay bales during construction (schedule work for dry season). Try retaining walls or terraces (local and state permits required).
