Description: Listed threatened ecosystems for South Africa, listed through NEM:BA 54(1). This list was gazetted in December 2011Ecosystem status consists of the following categories: critically endangered, endangered, vulnerable or least threatened. Ecosystem status was calculated based on the percentage of remaining vegetation area (i.e. not transformed by agriculture, mining, forestry plantations, roads and urban areas) and the biodiversity target set for each vegetation type. The ecosystem status of vegetation types which cannot longer meet its biodiversity target due to habitat transformation was set to “critically endangered” that means the percentage of remaining vegetation type is less than what is required to capture species diversity (biodiversity target). The ecosystem status of other vegetation types was set as follows:- if % of remaining area <60% of original area then status = endangered- if % of remaining area <80% of original area then status = vulnerable- if % of remaining area >80% of original area then status = least threatened.
