Willisbrook Preserve

126 acres

Willisbrook Preserve is a mix of woods and grassland meadows, including just over 20 acres of a rare ecosystem known as the Sugartown Serpentine Barrens. These barrens support a variety of plant species, many of which are threatened or endangered. In 2010, the barrens were designated as a Wild Plant Sanctuary by the PA Department of Conservation and Natural Resources.


Available at Willistown Township’s Serpentine Preserve, 143 Line Road, Malvern, PA.


Willisbrook Preserve was gifted to Natural Lands in 1963 by Jane Gordon Coxe Fletcher, whose family is best known for breeding champion Hackney and American Saddlebred horses.

Additional acquisitions in 1968 and 2004 expanded the preserve to its present size.
