Abstract

In the territory of Poland, <em>Rubus chamaemorus </em>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. <em>Rubus chamaemorus </em>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.

Highlights

  • Cloudberry (Rubus chamaemorus L.) is an endangered (EN) species in Poland

  • Rubus chamaemorus grows in the patch of hummockhollow mire which represents a mixture of two associations, possibly some regional variants of Sphagnetum fusci Luequ. and Sphagnetum magellanici boreale Jasn

  • At present there are no direct palaeobotanical data available which would support the idea of Rubus chamaemorus surviving in Orawa-Nowy Targ basin since the glaciation period
