Současný stav lokalit druhů Meesia triquetra a Paludella squarrosa (Meesiaceae) v České republice

Populations of two critically endangered moss species Meesia triquetra and Paludella squarrosa were investigated at all recently known localities in the Czech Republic. At each locality, population size, water chemistry, and vegetation characteristics were recorded. Recently, Meesia triquetra occurs at only 4 localities and its populations are mostly critically small, Paludella squarrosa grows at 10 localities and some populations are relatively large. Both species prefer slightly acid to neutral habitats with a stable water table height.
