The unique climate of the Southwest Nova Biosphere Region assists in providing a home to an extremely diverse collection of species. The most amphibians and reptiles east of Ontario can be found in the Biosphere Region. The biosphere Region is a hotspot for biodiversity and is home to 75% of Nova Scotia’s species at risk. It encompasses many terrestrial and aquatic ecosystems including the Acadian Forest, rolling plains, drumlins and coastal cliffs. The core of the biosphere Region is the largest protected wilderness area in the Maritimes. The surrounding counties are touched by the Atlantic Ocean and the Bay of Fundy which add to the distinct natural landscape.
