Our section of the trail along Wargo Road will soon provide a connection between the existing trail at Bristol-Myers Squibb, the Princeton Farms neighborhood, and beyond. We’re also actively working on completing a connection from Pennington’s Kunkle Park to Hopewell Borough Park. In addition, our more than 10 miles of foot trails on the Watershed Reserve will be getting an upgrade. In early 2008, the Watershed Association adopted a master plan for the Reserve. This plan calls for our trails to be organized more thematically, with clear points of The Watershed Reserve boasts more than 10 miles of origin and destination.

Shad in our ‘Shed? That would be something! The fish are harmed by ocean pollution, polluted runoff in streams and rivers, and dams. Overfishing has become a larger and larger problem as ocean trawlers consume more and more fish. With shad stocks crashing throughout much of their range, fishery biologists are seeking opportunities to make more spawning habitat available for the fish. To do so requires breaching dams, constructing “fish ladders” around dams Timberlane Takes that cannot be breached, and improving water quality.

Visual assessments pinpoint a take to reduce pollution. These include using the proper lack of streamside vegetation as one possible cause of this amount of fertilizers, reducing pesticide use, and cleaning impairment.
