A statewide effort to track Rhode Island’s seal population counted 590 seals in just two hours during Save The Bay’s annual survey, officials said.
The count, held March 18, brought together 43 scientists, naturalists and volunteers who monitored sites across the coast and Narragansett Bay. The effort, now in its 18th year, provides a snapshot estimate of how many seals are present at a given moment.
“The Rhode Island count is a really special event,” said July Lewis, Save The Bay’s volunteer and internship manager, noting the collaboration between shoreline observers and researchers on the water.
Harbor seals — the most common species in Narragansett Bay — are typically seen during colder months and play a key role as top predators. Gray seals, once rare in the bay, are increasingly common offshore, particularly around Block Island.
While this year’s total was slightly lower than last year, experts say long-term data shows the mainland population remains relatively stable. At the same time, gray seal numbers continue to grow, especially on Block Island.
Tara Plee, a marine biologist with the Rhode Island Division of Marine Fisheries, said the data helps scientists better understand seal movements and guide conservation efforts.
Volunteers were critical to the effort, particularly on Block Island, where covering the shoreline would be nearly impossible without community support, said The Nature Conservancy’s Kim Gaffett.
Officials also reminded the public to keep a safe distance from seals. Federal law prohibits disturbing marine mammals, and experts recommend staying at least 50 yards away on land or water. Signs of stress — including increased vocalization or movement toward the water — mean observers should back off immediately.
The annual count offers just a snapshot, but over time it helps paint a clearer picture of how Rhode Island’s seal populations are evolving.
