Note: The main data sources from which information has been gathered for the compilation of the table were published during 1987-1992. 0 = Extinct or probably extinct. Taxa no longer known to exist in the wild within the area of concern after repeated searches. 1 = Endangered. Taxa at risk of vanishing and whose survival within the area of concern is unlikely if the casual factors continue operating. 2 = Vulnerable. Taxa believed likely to move into the Endangered category (1) in the near future if the casual factors continue operating. 3 = Rare. Taxa that are not at present endangered or vulnerable but are at risk because of small total populations within the area of concern. 4 = Care demanding. Taxa which do not belong to the categories 1-3, but still require attention. Included are taxa which are relatively common but which have decreased dramatically and may move into the vulnerable category. ? = Indeterminate. Taxa known to be extinct, endangered, vulnerable or rare but where there is not enough information to say which of the categories is appropriate. Total number of known species referes to total number of plant species in country or county and is based on the data of World Resources Institute. Total number of known species for Germany, corresponds only to the former German Democratic Republic. n.a. = data not available - = missing category
