About Us

unnamedMember of JWW

NY/NJ Baykeeper is the citizen guardian of the NY-NJ Harbor Estuary. Since 1989, we’ve worked to protect, preserve, and restore the environment of the most urban estuary on Earth – benefiting its natural and human communities.

What’s an Estuary?

An estuary is comprised brackish water (combination of both fresh water and salt water) and forms a transition zone where our rivers and tributaries meet the sea. One of the most urban estuaries on Earth, the NY-NJ Harbor Estuary encompasses the Ports of NY and NJ, as far north as the Tappan Zee Bridge and as far south as Sandy Hook Bay. Our Estuary is home to a range of habitats including wetlands, shorelines, and coastal forests. A diverse species of birds including birds of prey, waterbirds, and migratory birds call the NY-NJ Harbor their home along with crabs, fish, eel, and clams.

Through our Estuary-wide programs we seek to end pollution, improve public access, conserve and restore public lands, restore aquatic habitats, encourage appropriate and discourage inappropriate development, carry out public education, and work with federal and NY/NJ state regulators and citizen groups as partners in planning for a sustainable future for the NY-NJ Harbor Estuary watershed.

Founded with the help of Hudson Riverkeeper and the American Littoral Society in 1989, NY/NJ Baykeeper is a wholly independent nonprofit with its own 501c3. NY/NJ Baykeeper has a full and part time staff, its own Board of Directors and many dedicated volunteers.

NY/NJ Baykeeper is the only bi-state full time advocate for the NY-NJ Harbor Estuary.

Our office is located at 30 Washington Avenue, Matawan NJ 07747.
