Historické a současné rozšíření Goodyera repens v České republice

A new locality of a critically threatened species Goodyera repens (Orchidaceae) was found in the south-western Bohemia. At present, there are only two localities in the Czech Republic (the other one in central Moravia) where the occurrence of this species was confirmed by the present authors. Both localities currently harbour only small populations not exceeding 0.5 m2. Goodyera repens should be considered a threatened species and is amongst the rarest orchids of the Czech flora. Historical research yielded 109 localities reported from the territory of the Czech Republic. In majority of these, the occurrence was short-term and those in which the species persisted for more than 50 years has been rarely reported. The longest occurrence was probably at a locality near the Orlické hory Mts where the species grew for 86 years. Ecology of Goodyera repens as well as protection and management of its existing localities are discussed.
