Royal Botanical Gardens (Ontario)

Royal Botanical Gardens (RBG) is headquartered in Burlington owning extensive environmental protection areas, historic sites and culturally relevant gardens in Hamilton, Ontario, Canada. It is one of the major tourist attractions between Niagara Falls and Toronto, as well as a significant local and regional horticultural, education, conservation, and scientific resource. The mandate is derived by a Provincial Act of 1941 centred on human interaction with the natural world and protection of environmentally significant lands that form the western tip of Lake Ontario. Royal Botanical Gardens spans an area of about 10 km by 4 km, dominated by two coastal wetlands, and glacial-carved landscapes that extend from the lake up to the Niagara Escarpment plateau. The various gardens and natural areas are accessed through nine public entrance locations. It is one of several Prescribed Public Bodies listed under the Ontario Heritage Act. In 2006, in support of the United Nations Convention on Biological Diversity, Royal Botanical Gardens was selected as Canada's National Focal Point for the Global Strategy for Plant Conservation (GSPC) by Environment and Climate Change Canada.The 980 hectares (2,422 acres) of nature sanctuary owned by the Royal Botanical Gardens is largely a remnant of the Dundas Marsh Game Preserve created in 1927. The properties now carry many cultural and environmental designations. Multiple national historic site features are associated with area, with the site featuring prominently as a landing and connection point to other regions of the Great Lakes. It is considered an important plant biodiversity hotspot for Canada, with a very high proportion of the wild plants of Canada in one area; is an Important Bird Area according to Bird Studies Canada; and is part of the Niagara Escarpment World Biosphere Reserve. More than 1,100 species of plants grow within its boundaries including the Bashful Bulrush (Trichophorum planifolium) which is found nowhere else in Canada, and the largest remaining population of one of Canada's most endangered trees, the Red Mulberry (Morus rubra). Both of these plants are listed as Endangered in Canada under the Species at Risk Act. In 2008, the RBG was designated as an Important Amphibian and Reptile Area by CARCNET, the Canadian Amphibian and Reptile Conservation Network. Several plants listed on various Endangered Species Protection programs are held for protection and education purposes in various garden areas. Unusually Royal Botanical Gardens is both the owner of the land under Cootes Paradise and Grindstone Marsh as well as regulator of activities on the water, despite it being an inlet of Lake Ontario. Water area activity regulation was formerly under the Hamilton Harbour Commission (Now Hamilton Oshawa Port Authority) as part of the areas historical federal port regulation. In the late 1970s the Harbour Commission and Royal Botanical Gardens made an agreement transferring regulation of use of the water area to the Gardens in support of its environmental protection mandate. However, Royal Botanical Gardens has no regulatory control over the quality of water flowing into its wetlands.

Cootes Paradise

Cootes Paradise is a property of the Royal Botanical Gardens at the western end of Lake Ontario, and a remnant of the larger 3700 acre Dundas Marsh Crown Game Preserve established by the Province of Ontario in 1927. It is a 600 hectare environmental protection and education area, dominated by a 4.5km long rivermouth wetland, representing the lake's western terminus. It is found on the west side of Hamilton Harbour and is located in the municipality of Hamilton, Ontario, Canada. The area is owned and managed by Royal Botanical Gardens (RBG), a charitable organization established in 1941 by the Government of Ontario. The wetland/marsh is part of the Cootes Paradise Nature Reserve, with these lands representing 99% of the unaltered lands along the local Lake Ontario shoreline (~25km). The site carries multiple designations, including a National Historic Site, a Nationally Important Bird Area (IBA), and is also central to inspiring the local principles for the World World Biosphere program. Within the regions local Niagara Escarpment World Biosphere, it is unique as the only point of physical connection with Lake Ontario. The marsh has also been referred to as the Dundas Marsh, a product of its surveyed location largely within the boundary of the former town of Dundas, and highlighted in conservation efforts initiated in the 1860s. Unusually, Royal Botanical Gardens is both the owner of the land under Cootes Paradise Marsh as well as regulator of activities on the water, despite it being an inlet of Lake Ontario. Water area activity regulation was formerly under the Hamilton Harbour Commission (now Hamilton Oshawa Port Authority) as part of the area's historical federal port regulation. In the late 1970s, the Harbour Commission and Royal Botanical Gardens made an agreement transferring regulation of use of the water/ice area to the Gardens' in support of the environmental protection mandate. However, Royal Botanical Gardens has no regulatory ability for the condition of water quality flowing into the marsh.
