Dogs and nesting plovers: why beaches limit dogs from April 1

April to September

Piping plovers nest right on the sand and raise chicks that cannot fly, and the birds treat dogs as predators. That is why many beaches ban dogs or require leashes from April 1 into late summer or early fall.

Why this time of year

On Plymouth Long Beach a partial dog ban initiated by the state Division of Fisheries and Wildlife runs April 1 to September 30 each year. At Cape Cod National Seashore, recurring seasonal pet closures run April 1 through October 15 at named beaches, and pets must be on a 6-foot leash wherever they are allowed.

How to notice it

  1. Before a beach walk with a dog from April through September, check that beach's own dog rules. They differ from beach to beach, and posted signs take precedence.
  2. Where dogs are allowed, keep them leashed and outside any roped-off or signed nesting area.
  3. Give the fenced areas a wide berth with your dog. State guidelines followed by The Trustees call for keeping people 50 yards from nests where the beach is wide enough, and even well-behaved dogs pose a threat to nesting shorebirds.

Try this with kids: Find the string fence and the signs on the beach. What do you think they are protecting?
