The emergence of new localities of Orobanche bartlingii Griseb. in the Silesian-Cracow Upland as a result of the spreading of Libanotis pyrenaica (L.) Bourgh. due to changes in land use : [poster]

Abstract

During the last few decades, many cultivated fields and grazed grasslands have disappeared in the Silesian- Cracow Upland. Therefore, abandoned lands occupy now a large area there. As a result of these changes, some plant species have significantly increased the area of occurrence. Libanotis pyrenaica is one of them. In many places it begins to behave like an expansive species (Fragment tekstu).
