Cypripedium calceolus in the Komi Republic

The point set contains data on the distribution of Cypripedium calceolus L. (Orchidaceae) in the Komi Republic. C. calceolus belongs to the group of flagship species of nature protection and is legally protected in all European countries and Russia. This orchid an emblematic plant from a conservation point of view. It is included in Appendix II of the Habitats Directive of the European Union (European Community Council Directive 92/43/EEC), classified as endangered on the IUCN Red List (IUCN 2001), and protected after its inclusion in regional catalogues of threatened species (Terschuren, 1998).
