Znovunalezení hlevíků Anthoceros neesii a Notothylas orbicularis v České republice

The occurrence of Anthoceros neesii Prosk. and Notothylas orbicularis (Schwein.) A. Gray in the Czech Republic was confirmed after 90 years. We rediscovered them at four stubble-fields in the Hrubý Jeseník Mts foothills. Only 7 individuals of Notothylas orbicularis were found at four sites, whereas Anthoceros neesii occurred together with the previous species at only three sites, however in a much bigger abundance. Rapid changes in agricultural management cause gradual disappearing of fields, which represent suitable habitats for hornworts, from submontane region of the Czech Republic. Consequently, both species could eventually vanish from our region in the future.
