Experts celebrate remarkable recovery of beloved creature in Long Island waterway
Long Island’s waterways are abuzz with good news: River otters, long absent from the area, are increasing in numbers, and scientists, volunteers and wildlife enthusiasts alike are rejoicing.
According to the report from WSHU Public RadioSemi-aquatic mammals have historically been eliminated from local waters due to unregulated trapping, pollution, and habitat loss.
But recent research shows that these charismatic creatures are beginning to repopulate areas around Peconic Bay and the North Shore.
Otters are native to Long Island but had largely disappeared by the mid-1800s. Early conservation efforts, including moratoriums on trapping and later reintroductions in western New York, helped rebuild populations in the north of the island—but until recently they had not made a strong natural comeback there.
Now, long-term research studies show that otters are expanding on their own, possibly moving into Long Island Sound from Connecticut and other nearby areas.
The rollback isn’t just anecdotal, according to Mike Bottini of the Seatuck Environmental Society. WSHU reported. For more than a decade, volunteers have combed shorelines, monitoring trail cameras and recording signs such as feces and fish debris to track otter activity. The latest results show an increased presence in known habitats and hints of expansion into new ones.

The return of sea otters mirrors other recent conservation gains and success stories such as the reintroduction of wild northern frogs in Colorado and the restoration of Atlantic sturgeon in Swedish rivers. Focused habitat protection and species management have helped animals return to areas where they were once extinct.
Growing otter presence also increasing community involvementMore volunteers have joined monitoring efforts, as well as conversations about protecting wildlife corridors and vents that allow otters to move safely between watersheds.
For residents who grew up without seeing an otter, spotting one now can be exciting. “They are a very charismatic breed.” Bottini told WSHU. “Otters are amazing! People who aren’t that interested in wildlife… are excited to have otters in the area.”
