The Royal Botanical Gardens (RBG) is headquartered in Burlington and also include lands 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. On 31 July 2006, the Royal Botanical Gardens was selected as the ''National Focal Point'' for the Global strategy for plant conservation (GSPC) by Environment Canada. The of nature sanctuary owned by the Royal Botanical Gardens is considered the ''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;〔(【引用サイトリンク】url= http://www.bsc-eoc.org/iba/site.jsp?siteID=ON005 )〕 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 Canada's most endangered tree, 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. ==History== Howard and Lorrie Dunington-Grubb undertook the landscape design in a naturalist style that combined native and exotic species. Initial sections of the RBG were built during the Great Depression in the 1930s as a make work project, under the impetus of Thomas McQuesten. It beautified derelict or undeveloped land in north Hamilton and west Burlington. For instance, a disused gravel pit was turned into the ''Rock Gardens'', by using stone relocated from the Niagara Escarpment. The original vision of the RBG was a mixture of horticultural displays and protected natural forests and wetlands. Formal permission was obtained in 1930 from King George V to call the gardens the "Royal Botanical Gardens".〔(【引用サイトリンク】url= http://www.rbg.ca/pages/more_about_history.html ) 〕 The first Director of the RBG, Dr. Norman Radforth, was appointed in 1947 and was a Professor of Botany at nearby McMaster University. In the early 1950s, Dr. Leslie Laking was appointed as Director and served until the early 1980s. Under his guidance, the institution developed into the major entity it is today. With approximately 1,100 ha (2,700 acres) of property, the Royal Botanical Gardens is one of the largest such institutions in North America. In 2006, the Auxiliary of the RBG published ''Love, sweat and soil: a history of Royal Botanical Gardens from 1930 to 1981'' authored by Dr. Laking. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Royal Botanical Gardens (Ontario)」の詳細全文を読む スポンサード リンク
