Seymour B. Cooper Sanctuary (Frederick County)
In 1978, MOS acquired this 14.3 acres of land as a gift from the Nature Conservancy which had received it from the estate of the late Seymour B. Cooper. It is approximately 3.3 miles south of the Pennsylvania border and about the same distance from Camp David. It is located on the lower slope of 1700-foot Piney Mountain.
The property can be identified by a large sign with the name of the sanctuary. “No Hunting” signs indicate the boundaries and painted stakes mark the corners of the property.
The habitat is a uniform deciduous forest of mostly oaks and maples. Chestnut Oak is the dominant tree, and the canopy averages 50-60 feet. The presence of American Chestnut saplings and older fallen logs indicate that this area was probably logged about the time of the Chestnut blight.
