Bronx River Restoration

In the 1600's, New York City's Bronx River was a drinking water source and a sylvan haven for beaver, oysters, and herring. It became blighted as urbanization progressed, reincarnating as an industrial power source, an open sewer, and a garbage dump. Today, landscape ecologists are reconstructing the waterway's ecological history as a reference point for its restoration effort. Watch conservation teams coax new life into the Bronx River as they restock it with native fish, lay down oyster beds, and remove invasive species along its shores.
