The rugged beauty of Georgian Bay Islands National Park is characterized by the rocky outcrops and spindly windblown pines that have come to symbolize its landscape. Georgian Bay Islands has the greatest diversity of reptiles and amphibians of any Canadian National Park, and is one of the last refuges for the threatened Eastern Massasauga Rattlesnake. Many of the challenges faced by park management are related to reconciling preservation with the pressures of recreational use. One of the park's great success stories is that of the majestic osprey, for whom neighbouring cottagers and the park have erected nesting poles.
