Low Impact Landscapes with Caroline Toole of Lake of the Ozarks Watershed Alliance

This morning, Caroline Toole, of the Lake of the Ozarks Watershed Alliance (LOWA), came all the way from Climax Springs to Waynesville, just teach a class about the principles of low impact landscaping.

Caroline is the project manager for LOWA, an organization formed by a group of proactive residents  to protect and preserve the Lake of the Ozarks and its watershed.  (Their website is  http://www.soslowa.org/.)  According to LOWA, “[a] watershed is an area of land where the runoff from rain and snow will ultimately drain to a particular stream, river, wetland, or other body of water.  Healthy watersheds provide plentiful drinking water supplies, habitat for fish and wildlife, and water for irrigation, industry, or recreation activities. Without clean water supplies, our society would be radically changed from what it is today.”

The Waynesville, Missouri area is in the Upper Gasconade Watershed.  Information about this watershed can be found here.

Low impact landscapes (LILs) are measures individuals can take on their own properties to reduce the amount of runoff reaching bodies of water within their local watershed.  Some basic LILs that homeowners can implement on their properties include:

1)  Vegetated buffer strips, which are are rows of native perennial plants that are placed in such a way as to intercept storm water runoff before it goes into the watershed.

2)  Rain gardens, which are depressions dug into the ground to catch runoff and allow that runoff to slowly soak into the ground.  Native plants are often the plants of choice in a rain garden because they are adapted to Missouri’s soils and climate, they are low maintenance, they attract wildlife, they solve landscape problems, and they protect and enhance biodiversity.  For excellent information on Missouri natives, check out these sites: Missouri Wildflowers; Missouri Wildflower Guide; MO Extension Publication; Grow Native, and MO Department of Conservation Info.

3)  Compost socks are mesh tubes about three feet in length that are filled with a growing medium.  These tubes can be used as a retaining wall.  You can put plants right into the socks and create a living wall in your garden!  Once the plants are established, the compost socks become beautiful, permanent, low maintenance additions to the landscape.

4) Before a homeowner gets planting, a soil test should be done to see whether any fertilizer is needed, and if so, how much and what kind needs to be applied.  Applying fertilizes based on the results of a soil test helps prevent excess fertilizer from entering the local watershed.  For more information on soil testing, call your local extension center or see these MU Extension publications.

Caroline’s class included a practical exercise.  The group evaluated the problem hillside in our demonstration garden:
