Site description The Greater Rondeau Area is situated on the shoreline of Lake Erie, southeast of the town of Chatham. In addition to Rondeau Provincial Park, this site encompasses adjacent areas including Rondeau Bay and associated marshes and adjacent fields, Bates marsh, Erieau pier, harbour and beach, McGeachy's Pond, and the Morpeth Cliffs. Rondeau is the largest provincial park in southwestern Ontario. It is a low-lying sand spit that consists of a series of ridges and sloughs. A variety of habitats are present which contribute to the bird diversity. These habitats include productive southern hardwood forests, sandy beaches and wetlands ranging from woodland sloughs, to a large marsh and productive inland bay. The unique habitats of the park and surrounding area support many nationally vulnerable, threatened, and endangered species of flora and fauna.
