Exotic plants are edging out native species at Radnor Lake Natural Area, the Warner Parks and other Nashville parks.
The problem, and the solution, could come from local gardeners.
Officials at Warner Parks are reaching out to the surrounding community to teach individuals about which plants to avoid in their private landscaping.
Park officials started to become aware of the problem about 15 years ago when birds that ate fruits from exotic plants in nearby private gardens dropped the seeds in the parks.
In the first program offered on Feb. 10, Urban Forester Jill Smith will lead hikers along the Harpeth Woods trail in the Warner Parks to remove exotic vines.
