Learn About William Post
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.
Stewardship projects at this property include invasive plant surveying and eradication and trash removal. Annual surveys are also performed.
