William Post Natural Area

Bernardsville, Somerset County


About William Post Natural Area

This 22-acre site was donated to the Upper Raritan Watershed Association by Marion and Thomas Peters in 1967.  They wanted to ensure that the property would be used in perpetuity for conservation, open space preservation, conservation education, vegetation and wildlife management and the protection of the headwaters of the Mine Brook. 

The west branch of Mine Brook flows through the site, and a diverse mix of plant species can be found here.  These vary across the property with changes in topography and soil moisture.  Birch, Oak, Tulip Poplar, Red Cedar, White Ash and Black Cherry trees give way to Red Maples and shrubs such as Highbush Blueberry and Smooth Alder.  Skunk Cabbage and Sensitive Fern are abundant in wetter areas.

The William Post Natural Area runs along the west side of Claremont Road both north and south of its intersection with Post-Kunhardt Road.  For directions to the site from your location, follow this link.  Pull-offs areas for parking are available along Post-Kunhardt Road, and offer easy access to the site.
