Although it has not been confirmed, the Hudson River is purported to be the world's longest tidal river, reaching 150 miles. The Hudson River is home to both the shortnose and Atlantic sturgeon. Their appearance today is almost the same as when dinosaurs walked the earth during the Triassic period, 245 to 208 million years ago. They are among the oldest living fish species. You can find more information on our sturgeon conservation guides.
|State Ranking Justification||
This community is restricted to tidally influenced areas of the state. There is one large occurrence (Hudson River) and several small examples known from Long Island (e.g., Nissequogue and Carmans rivers). Tidal rivers are moderately threatened by pollution, shoreline development, dredging, commercial shipping, recreational overuse, and invasive species.
The number and acreage of tidal rivers in New York have proabably become stable in recent decades. The quality of the water in tidal rivers has probably improved in recent decades.
The number and acreage of tidal rivers in New York have probably declined moderately from historical numbers likely correlated with shoreline development and dredge spoil deposition. Water pollution was a very serious threat several decades ago, but has improved with the advent of pollution control facilities and regulations.
