The Whites Mill Tract, approximately 100 acres in size, was purchased by Salford Township in 1998 as open space. It is located in a forested landscape comprising about 10,000 acres that stretches across upper Montgomery and Bucks Counties. Because of the extensive contiguous forested area, this region is the target of several efforts to protect the natural resources and its ecological integrity (see Figure 1). The Natural Lands Trust (NLT) and the Montgomery County Conservancy have collaborated to secure conservation easements on the 1700 acre Musser Scout Reservation in the Unami Creek Valley. NLT is also working with Milford Township, Bucks County to extend protection efforts upstream along the Unami and Ridge Valley Creeks. Marlborough Township, Montgomery County recently purchased the Camp Skymount property, which is located about three-quarters mile upstream from Whites Mill pond. NLT's Fulshaw-Craeg Preserve is located approximately one mile downstream. In addition NLT holds conservation easements on a number of private properties in the area.
