Falcon Flats Wetland Restoration project. Wetlands used to be considered useless swampland, but no longer. We now know that wetlands provide clean water to surrounding communities, acting as "kidneys" to remove impurities and as buffers to prevent flooding. Thirty percent of all endangered species rely one way or another on wetlands, for nesting, resting, or feeding. In Ohio, almost ninety percent of the wetlands have been destroyed or degraded in the last 200 years imperiling many of the plants and animals that need wetlands to survive. The Ohio EPA has identified Sugar Creek as the second most polluted stream in Ohio. Restoring and enhancing the wetlands and introducing a stream buffer promotes biodiversity as well as clean water.
