Is Rubus perrobustus expanding to the north? – new records from Poland
Grzegorz Åazarski
Abstract
Rubus perrobustus Holub is an endemic species of the Europe, whose range stretches from northern Austria, southern Germany, the Czech Republic, Slovakia, northern Hungary, South-western Poland to western Ukraine. Distribution of the species is not completely known as evidenced by its new localities found in recent years in different parts of Europe. The aim of the paper is to present new data on occurrence of R. perrobustus in Central Europe (Małopolska Upland, southern Poland). Five new localities of the species were found during phytogeographical studies in the Świętokrzyskie Mountains (central part of Małopolska Upland) using the cartogram method. The new data of R. perrobustus distribution indicate that the Świętokrzyskie Mountains and their foreland are the next area of its concentration in Central Europe. The recorded localities are among the most northerly. They may be the result of modern expansion of the species to the north from the eastern part of the Polish Carpathians. However, the similarity of distribution of R. perrobustus and a few other brambles recorded in the Polish mountains indicates that the localities found are rather the result of old postglacial migration. One way expects more localities of the species for instance in the uplands of southern Poland and therefore further extension of its range.
