The Feds close my favorite beach in the summer to protect the Plover. Plum Island, MA is a barrier island north of Boston. The plovers nest on the beach. They close down miles(5-6 literally)of beach in May , June and July. Typically they do not reopen until mid August.
The state of MA is a little more reasonable. They put up snow fence 30’ around the nest.
In Northwest Lower Michigan, in the town of Cross Village, there is a sign on the beach saying that this strip of beach is closed because of the “endangered” Piping Plover.
The thing is, there haven’t been any sightings since the mid 1930’s!
