Spear Farm Estuary Preserve

Owned and managed by the Town of Yarmouth, Spear Farm Estuary Preserve is a scenic 55-acre property with diverse habitats, ranging from stately oaks and pine forest to the open salt marshes of the Royal River estuary, and a small freshwater pond with a fringing marsh. The preserve includes 1.6 miles of gentle, well-maintained trails over rolling, coastal terrain perfect for foot or ski travel and ideal for bird watching. There is an excellent picnic spot and overlook on the pond’s northern shore, as well as on the edge of the salt marsh. In the winter the pond offers great skating opportunities, with attention to safety.  Conservation Easements held by the Royal River Conservation Trust protect the property.

Birding and Ecology

The interface between the freshwater impoundment and the salt marsh create the opportunity for a wealth of wildlife sightings. The freshwater pond was constructed in 1968 by the US Fish & Wildlife Service. Five interpretive signs stationed along the trail describe aspects of local ecology. Good birding sites are in the oak and pine stands, along the bluffs, the salt marsh edge, on the earthen dam, and the north end of the freshwater pond.

Conservation History

Owned and managed by the Town of Yarmouth, the property is protected by a conservation easement held by the Royal River Conservation Trust. The 55 acre preserve was conserved in three phases, along with an upriver 17 acre parcel. The most recent phase of conservation was a gift of land in 2011 by the Cattell family. The first two phases, in 2004 and 2005 were made possible by remarkably generous donations from neighbors and Royal River Conservation Trust members, the Land for Maine’s Future program, federal funds, and the Trust for Public Land. A 17 acre nearby section of salt marsh, just upriver, was donated to the Royal River Conservation Trust by Ann Donaghy and Nancy Gunzelmann in 2004. This Management Plan  includes detailed background information on history, ecology, geology, forestry, management, and more.
