Named for this small tributary to the Musconetcong River, streams, hardwood forest and granite rock boulders frame much of the rugged scenery surrounding the Lubbers Run Preserve. The 90-acre property surrounds a unique assemblage of open and emergent wetlands where beavers take full advantage of the shoreline terrain for building their dams. Here amongst the twists and turns of the stream channel, waterfowl and wading birds find cover for feeding and resting. The surrounding hardwood forests ring with the avian song of interior forest nesting birds such as the ovenbird and veery. Beech and oak trees dapple shade over rare orchids, buttercups and other wildflowers of the woodlands. All this is preserved open space thanks to generous private donations of conservation land.
Visitors can follow a paved hiking/biking path though open space adjacent to the Byram Township school grounds off Mansfield Drive. Hikers looking for an off-pavement experience can follow several unmarked and un-maintained woods paths. The ecology club at the neighboring Byram Township School uses Lubbers Run as an outdoor ecological classroom.
