Manchester White Cedar Swamp  

Countryside Boulevard, Manchester, NH

The 42-acre Manchester Cedar swamp is the globally rare Atlantic white cedar/giant rhododendron swamp. It occurs at fewer than 10 swamps in New England, and this is the only one north of Massachusetts.

The Nature Conservancy’s (TNC) Manchester Cedar Swamp Preserve was protected through an innovative settlement agreement in 1999 among the City of Manchester, U.S. Environmental Protection Agency and the N.H. Department of Environmental Services.  Under the agreement, the City agreed to take actions to improve Manchester’s environment by implementing a $5.6 million Supplemental Environmental Program, part of which included $2 million to permanently protect this ecosystem from development.  Also vital to protecting this preserve was a grant from the New Hampshire Land and Community Heritage Investment Program (LCHIP). TNC was asked to own and manage these special lands. At more than 600 acres, the preserve is the single largest permanently protected block of conservation land in Manchester.

Viewing Information

You can hike through 1.8 miles of trail that includes three loop trails through the cedar swamp, white pine and red oak woodlands, and giant rhododendron thickets.  The cedar loop trail leads you through a small section of the cedar swamp where you’ll see Atlantic white cedar, giant rhododendron, winterberry, cinnamon fern, and a large black gum tree. The rhododendron loop trail leads through several thickets of giant rhododendron which are in full bloom in June.  You can also walk along the wetlands of Millstone Brook which is a great place to see wetland birds like great blue herons and common yellowthroat warblers and wildlife like deer, mink, and beaver. A variety of woodland songbirds can be heard and seen here in the spring and summer.
