Bear-Paw Regional Greenways acquired this 52-acre property in June 2010. Most of the road frontage was going to be subdivided into residential house lots when the property was protected by a conservation easement purchased by the Natural Resources Conservation Service Wetland Reserve Program and then conveyed to Bear-Paw. The North River Preserve is made up of an Appalachian oak-pine forest with hemlock and hardwood pine, as well as a floodplain forest along the North River corridor. The property includes over 3,000 feet of frontage on one or both sides of the river and a wide variety of wetlands associated with it: floodplain, swamp, marsh, peatland, oxbows, and vernal pools. Much of the property is on the north side of the river and is not easily accessible during high water. It is directly connected to the Mulligan Forest, a 2,000-acre conservation property owned by a local family.

The property is located on Stage Road (NH-152) in Nottingham. From NH-4 in Northwood, take NH-152 east 5.6 miles to the North River Preserve (on your right, just before crossing the North River and Flutter Street). From NH-125, take NH-152 west 3.7 miles to the North River Preserve (on your left, just after crossing the North River and Flutter Street). The North River Preserve parking area was improved through the Natural Resources Conservation Service Wetland Reserve Program and has room for several cars. It is not maintained in the winter but there is parking at the Nottingham Town Offices across the street.

The Nottingham Town Hall Trail is in the North River Preserve.
