Crows Neck Nature Reserve protects much of a two kilometre sand beach and dune system, with coastal headland, near Baccaro, in southwestern Nova Scotia.
Crows Neck Beach is one of the most important nesting beaches for endangered piping plover in Nova Scotia. The beach is especially sensitive to disturbance during nesting season. The reserve and surroundings are frequented by other shorebirds, including common and arctic terns.
The nature reserve includes a few parcels transferred to the Province by the Nova Scotia Nature Trust.
The boundary of the nature reserve does not extend below the mean high-water mark. Activities that occur in the intertidal zone behind the beach, such as clam digging and hunting, are not affected by the designation.
