The Shire of Denmark has designated the northern part of Prawn Rock Island and associated sand / mud flats as a bird sanctuary. This is largely to protect the migratory and resident shorebirds from disturbance especially from off-leash dogs. There is currently a pair of Pied Oystercatchers nesting on the island. Fences and signs have been erected on the east and west side of the island to encourage people not to enter the Bird Sanctuary. There have been some migratory birds seen in the area of the sanctuary, notably a Terek Sandpiper, more are expected as the water level drops (hopefully).
