Occurrence of Trichocolea tomentella (Ehrh.) Dumort. (Marchantiophyta, Trichocoleaceae) in the Polish Carpathians: distribution, habitat preferences, current threats, and recommendations

Abstract

This paper describes the vertical and horizontal distribution, habitat preferences, threats, and conservation status of Trichocolea tomentella in the Polish Carpathians based on the analyses of 138 localities. The species prefers wetland habitats, mostly within forests, such as areas in the vicinity of springs (34% stands), stream banks (32%), wet parts of the forest floor (20%), and mountain bogs (16%). As a consequence of the decrease in the areas of these habitat types, localities of T. tomentella are threatened with extinction. Therefore, according to the IUCN standards, this species should be placed in the near threatened (NT) category in the Polish Carpathians.
