The ability to take relaxing walks through beautiful natural areas just min- utes from your back door is one of the reasons residents love this town. Many of these open natural areas in town are on conservation land and one small parcel is getting extra atten- tion by the East Kingston Conservation Commission to make it even more accessible to residents. The Pheasant Run Wetland Study Area is a 5-acre wooded property that contains an interesting wetland with a small pool and stream. Access to the property is off of Pheasant Run Road and will be marked this year with signs bought with a grant from the Piscataqua Region Estuaries Partnership and the Otto Haas Charitable Trust 2 Fund of the New Hampshire Pheasant Run Wetland Study Area is open year around during daylight hours. To visit the area park on the side of the road on Charitable Foundation. Pheasant Run Lane (image above). This year the area will be marked with signs that mark the boundaries of the property.

Water pollution, especially dissolved nitrogen, is a significant problem in Great Bay, which is fed in part by the Exeter River that flows though East Kingston. According to the State of Lush, Natural Vegetation Filters Water Polluted Runoff the Estuaries Report published in and Lets It Soak Into The Ground From Roof 2009, nitrogen levels have increased by 44% in the last 28 years - due pri- marily to increased development. Buffers throughout the watershed will help reduce nitrogen and reverse this troubling trend. Groundwater Recharge Since nearly everyone in East Kings- ton relies on well water in their homes, A Pond, River, Marsh, the benefits of buffers to groundwater Or Other Wetland quality is very important.
