Abstract

Schoenus ferrugineus L. is one of the diagnostic species of calcareous fens, which are floristically rich and scattered locally in Europe. 25 new occurrences, most of them recent ones, have been found in Russia, mostly from the eastern border areas of the species. The new locality in Murmansk Region, reported here, corresponds to the northern limit of this species in Europe, and is situated about 60 km north of the Arctic Circle. The new site is described and the distribution and ecology of the species in Murmansk Region are discussed. It is proposed to change the status of this species in the Regional Red Data Book to ’Critically Endangered’.
