Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for the Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.〔WWF and IUCN Centres of Plant Diversity: a guide and strategy for their conservation (Cambridge: World Wide Fund for Nature and IUCN, 1994-1997)〕 In 1998 there were 234 Centers of Plant Diversity registered across the globe, each bearing a rich diversity of endemic plant species that are of great value to humans and their native ecosystems that tend to be under unique edaphic conditions.〔(EarthTrends: The Environmental Information Portal, Endemic Bird Areas and Centers of Plant Diversity in Forests )〕 Many CPD's are enlisted as a part of a legally protected area though they do not necessarily have legal protection automatically assigned to them. A CPD Is recognised primarily as a portion of a greater protected area that holds particularly significant biodiversity, likely to have a high number of irreplaceable plant species which are of high vulnerability. ==See also== World Wildlife Fund International Union for the Conservation of Nature Protected Areas Biodiversity 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「Centres of Plant Diversity」の詳細全文を読む スポンサード リンク
