Newly discovered relic population of Rubus chamaemorus L. in the Western Carpathians

In the territory of Poland, Rubus chamaemorus is a rare glacial relict. Its localities known to date were in the northern part of the country and in the Sudeten Mountains. In 2002, a new locality of this species was discovered in the Orawa-Nowy Targ basin in the Carpathians. It is the southernmost locality in the European distribution area of this species. Rubus chamaemorus grows there on a raised bog in communities of the Oxycocco-Sphagnetea class. The spatial structure of the population depends on microhabitats reflecting the hummock-hollow structure of the peatbog
