Black Bear Information:

black bear

 Black bears are now recognized as an important natural resource in New Jersey and as part of the state's heritage. They have been sighted throughout the state. People can see bears in forests when they are hiking and camping, and some people even see bears in their yards. The links below, from the NJ DEP Division of Fish & Wildlife, provide information on how residents can best co-exist with bears. The most important recommendation is don’t feed bears and keep garbage covered. It is illegal in New Jersey to feed black bears either intentionally or unintentionally. Anyone who feeds bears could face a penalty of up to $1,000 for each offense.

Report bear damage, nuisance behavior, or aggressive bears to the West Windsor Township Police Department at (609) 799-1222 and to the NJ DEP hotline at (877) 927-6337.

Community Profile

  • West Windsor Township was incorporated in 1797 encompassing six hamlets: Port Mercer, Penn's Neck, Clarksville, Grover's Mill, Dutch Neck, and Edinburg.

By the 1800's, this prosperous farming community was prized for its central location between New York and Philadelphia. A seventh hamlet was added called Princeton Junction when the northeast corridor rail station was added in the 1860s.
