McDonald Marsh, Frelinghuysen NJ - 3 acres

unique features

The property is principally a freshwater wetland, which makes it an important site for the protection of water quality and a buffer against flooding. It is habitat for sphagnum (peat) mosses, various sedges, high bush blueberry, flag iris, and a great diversity of other plant species associated with wetlands. It is a very active site in the springtime for breeding amphibians.


McDonald Marsh was RVC's first preserve.  The owners - Walter and Carol McDonald - donated a conservation on the property, because of their desire to see it protected forever. In 2014 the owners donated the property to RVC, to further ensure it's permanent protection and proper management. Frelinghuysen Township accepted transfer of the easement, to ensure that there are two entities to guarantee protection of the property.
