The Sharon Land Trust has launched an effort to preserve environmentally important property on River Road south of Cornwall Bridge. The project consists of two abutting riverfront parcels that would also open 2742 feet of scenic Housatonic River frontage for fishing and public access.The purchase of a conservation easement on approximately 20 acres of the farm of Charlotte and Denny Frost includes 1480 feet of river frontage and an island in the river. It would also protect a very rare kettle pond on the property. Kettle ponds were formed as glaciers retreated and resulted in a depression which exposed the water table to the surface. Kettle ponds have no defined inlet or outlet and no fish. As a result, like vernal pools, they can be host to a myriad of amphibians including woodland frogs and salamanders.
The most celebrated kettle pond in the New England landscape is Walden Pond, made famous by naturalist Henry David Thoreau. Sadly, Walden Pond has been degraded by development. The land trust hopes to prevent that from happening to Sharon’s diminutive Walden Pond.
A preliminary study of the Frost’s kettle pond shows the presence of amphibians classified as both important and very important species. If the project is successful, a plan of conservation and year-long study will be developed and implemented.
The kettle pond in Sharon is also environmentally important because it marks the presence of a defined stratified drift aquifer that is hydraulically connected to the Housatonic River. According to Star Childs of Ecological and Environmental Consultancy Services, the water found in stratified aquifers is naturally filtered and purified as it passes through sand and gravel, thus ensuring high quality discharges to the river.
“Protecting a stratified drift aquifer from surface development and the subsequent potential for subsurface pollution is essential for the maintenance of clear water. The State of Connecticut DEP has made stratified drift aquifers a high priority for future land protection efforts” he said.
The second parcel in the land trust project is a 5 acre field to be purchased from CL&P. It abuts the Frost property and has another 1262 feet of river frontage. It connects directly on the north to miles of conserved riverfront owned by the National Park Service. The CL&P land will extend a trail system that runs all the way to the town of Kent. Its acquisition will secure new public access for fishing, boating, hiking and wildlife observation.
The conservation easement on the Frost property also includes creation of a low impact footpath on their waterfront and the Frost family plans to use their trail as a catalyst for neighbors to continue the trail northward along the river.
The land trust, in conjunction with the Housatonic Valley Association, has applied for a $702,338 grant from the Housatonic River Basin Natural Resource Restoration project. The purchase and the grant application have been supported by the Nature Conservancy, the Housatonic River Commission and the Town of Sharon.
Mr. Power said the entire cost of the project is about $1 million. The land trust will have to raise $300,000 and the HVA has pledged $30,000, but he has full confidence that the money can be raised if the grant is awarded.
The environmental importance to aquatic life and the beauty of this land combined with the public benefit of extending the trail system should make the purchase very appealing to Sharon donors.
Our project has passed the first two screens of the DEP, and we anxiously await the long overdue decision on the grant.
