Conservation Management Area (CMA)

In 1998, with the help of many volunteers, GSWA began the work of ecological restoration at a 23-acre site in Harding Township. To improve public access, hundreds of yards of trails have been cleared and boardwalks have been put in over marshy areas. The restoration goal is to reduce the number of invasive plant species on the site and to increase the number and diversity of native species. The area serves as an educational tool to inform area students and other residents about the need for, and importance of, ecological restoration on land throughout the watershed. Ecological restoration projects on six of the 23 acres within the area demonstrate the impact of invasive species on this ecosystem, different techniques for removing invasive species, encouraging re-growth of native species, how stream banks can be stabilized and restored, and how homeowners can implement these techniques on their own property. We are also experimenting with a variety of deer control techniques.

We invite you to enjoy the natural beauty of the CMA on Tiger Lily Lane at your leisure. And if you’d like to plan a group hike and guided tour, please contact Hazel England, GSWA’s Land Steward, at
