Buffer Initiative

Vegetative buffers, also called buffer strips or greenbelts, located between land and water help filter pollutants and improve water quality.  Buffers absorb excessive stormwater runoff and nutrients such as phosphorus, a culprit behind algae blooms.

 

The Watershed Center conducts buffer surveys of private and public lands, and educates the public about the aesthetic and water quality benefits of greenbelt gardens.

Do you want to increase the long-term value of your substantial investment in waterfront property while protecting water quality?

 

One of the easiest, most beautiful and cost-effective ways to do this is to incorporate a greenbelt garden in your landscaping.  A greenbelt garden is simply a strip of natural vegetaion such as native plants, tall grasses, shrubs and trees planted between your lawn and the water.  Greenbelts prevent erosion, sediment and nutrients from reaching waterways.

 

Turf grass lawns that extend all the way to the water's edge without any trees or shrubs are less effective at absorbing nutrients that cause water quality problems such as algae growth.  A diverseity of longer rooted plants such as trees, shrubs, plus native grasses and flowers is more effective at absorbing nutrients and preventing erosion.

 

Lawns create more runoff than wooded areas, as they absorb less rain.  Bare lawns carry eight times as much phosphorus to waterways than wooded areas the same size.

 

 

 

Benefits of Greenbelt Gardens

 

Greenbelt buffers provide these aesthetic, time-saving and money-saving benefits: 

  • Saving as much as 48% in maintenance costs as compared to traditional landscaping
  • Spending less time on high-maintenance lawn care such as mowing, weeding and fertilizing--that means more leisure time for you! 
  • Preventing erosion, which is vastly more cost-effective than repairing shoreline
  • Enhancing your view of the lake by framing it with plants, grasses, shrubs and trees to render your scene even more picturesque
  • Creating a meandering path to the shore, incorporating the cherished element of unfolding and expanse in your landscape plan
  • Attracting birds, butterflies and other wildlife

The Beauty of Native Plants

 

Native plants, grasses, shrubs and trees are preferable.  Native plants are well-suited to your soil type and climate, making them remarkably hardy.  This saves you money from having to replace plants that perish.

 

Native plants are naturally drought-resistant, very low maintenance and pest repellent.  they also attract diverse plant and animal life.  Your yard will be teeming with beautiful birds and butterflies!

 

The roots of native plants are deeper than those of grass.  Thus, they are far superior in absorbing water, preventing erosion, plus reducing and cleansing runoff.  Native plants, grasses, shrubs and trees stop pollution from reaching the water.  They trap sediments and absorb excess nutrients such as phosphorus.

 

Making the Transition to a Greenbelt Garden

 

Soil type, slope and vegetation mix are all factors in designing an effective greenbelt.  There is no one-size-fits-all design.  Your greenbelt garden can be as unique as your home. 

 

Generally, the wieder and deeper your greenbelt, and the higher the diversity of plants, themore effective it will be in protecting water quality.  The depth that your greenbelt extends inward from shore will depend on soil type, slope, runoff area and other factors.  The Watershed Center can put you in touch with expert advice for specific design ideas.

 

If you're building a new home, you can easily incorporate a greenbelt into your landscape plan.  Avoid large hardscaping elements such as seawalls.

 

If your existing lawn extends all the way to water's edge, simply stop mowing next to the water.  This will allow naturally occuring native seeds in the soil to germinate.  Beautiful things happen when you quit mowing!  Native plants beging blooming.  This is free landscaping!

Torch Lake Buffer Survey Top

In 2007, the Watershed Center conducted a survey of Torch Lake's 41-mile shoreline to assess its greenbelt buffer.  The shoreline zone extends 50 feet inland from the ordinary high water mark.  Funding for this survey of Michigan's largest inland lake was provided by the Michigan Department of Environmental Quality. 

 

All 1,752 properties were surveyed around the lake.  The Watershed Center contracted with White Pine Associates, and more than 20 volunteers from the Torch Lake Protection Alliance and Three Lakes Association provided field assistance.

 

Some general results of the survey show that:

  • 86% of the shoreline is developed
  • 32% of the greenbelt buffer is in very good to excellent condition; 44% is in poor to very poor condition
  • 7% of the shoreline erosion is severe

Results are also available for each individual parcel.  If you would like to obtain results for your property, please contact Sarah U'Ren at 231.935.1514.

If you would like to receive a one-on-one consultation about greenbelt buffer improvements specially suited to your property, contact John Nelson, Grand Traverse Baykeeper for the Watershed Center, at 231.935.1514.
