October 25, 2021 — Over the past decade the waters around Cape Cod have become host to one of the densest seasonal concentrations of adult white sharks in the world. Acoustic tagging data suggest the animals trickle into the region during lengthening days in May, increase in abundance throughout summer, peak in October and mostly depart by the dimming light and plunging temperatures of Thanksgiving. To conservationists, the annual returns are a success story, a welcome sign of ecosystem recovery at a time when many wildlife species are depleted. But the phenomenon carries unusual public-safety implications. Unlike many places where adult white sharks congregate, which tend to be remote islands with large colonies of sea lions or seals, the sharks’ summer residency in New England overlaps with tourist season at one of the Northeast’s most coveted recreational areas. Moreover, the animals are hunting in remarkably shallow water, at times within feet of the beach. This puts large numbers of people in close contact with a fast and efficient megapredator, historically the oceans’ most feared fish.

Among critics of the white-shark status quo, disillusionment runs deep. Other members of the Cape Cod Ocean Community, including Drew Taylor, reject the reliance on nonlethal approaches. Taylor proposes challenging policy and amending federal law to allow communities to set preferred population levels for white sharks and gray seals and permit hunting or fishing to reduce their numbers. Conservation laws, he said, were understandable in intent but lack tools to deal adequately with rebounds of this scale. “How can you write a law that protects something in perpetuity?” he said. His views, like those heard in human-wildlife conflicts elsewhere, can be summarized like this: It’s perfectly reasonable to find lions or cobras or white sharks captivating but not want hundreds of them feeding in your neighborhood park. He blames federal policies for fostering biological and social dynamics that force people to yield without question or recourse to dangerous or nuisance animals. Marine mammals, he noted, enjoy protection that terrestrial mammals do not; a sole black bear that roamed Cape Cod in 2012, for example, was promptly tranquilized and removed.
