Royal Botanical Gardens (RBG) is the largest botanical garden in Canada, a National Historic Site, and Canada’s plant biodiversity hot spot. RBG features, within its dozens of documented collections, approximately 42 living collections displayed in five major garden exhibition areas. RBG’s natural lands consist of 2,400 acres of Carolinian forest, Niagara Escarpment cliffs, rare oak savannah and coastal wetlands accessed by 27 km of walking trails. They are home to more than 50 at-risk species and a major stop-over point for thousands of migratory birds.
