The Niagara Escarpment Biosphere Reserve (French: Réserve de biosphère de l'Escarpement du Niagara) (established 1990) is a UNESCO Biosphere Reserve located in Ontario, Canada. The reserve stretches 725 kilometres (450 mi) along the Niagara Escarpment from Lake Ontario (near Niagara Falls) to the tip of the Bruce Peninsula (between Georgian Bay and Lake Huron). The Escarpment corridor crosses two major biomes: needle leaf forests in the north and temperate broadleaf forest in the south.
