The paper contains a list of 39 liverwort species collected on decaying wood (logs, stumps and snags) and on tree-fall disturbances (root plates, pits and mounds) in forest communities in the Karkonosze. Three of these species are threatened in Poland: Cephalozia catenulata, C. leucantha, Marsupella emarginata and three are partially protected by law: Cephalozia catenulata, Bazzania trilobata i Ptilidium ciliare. The most frequent species in the study area are: Calypogeia integristipula, C. azurea, Cephalozia bicuspidata, Lepidozia reptans, Lophocolea heterophylla, Lophozia ventricosa.
The paper presents a new locality of Ulota crispa (Hedw.) Brid. found in Central Poland. The new site is situated in the Wólecki Forest, 10 km to the east from Opoczno city. A small tufts were observed in May 2012 on a bark of goat willow (Salix caprea) in managed forest. The main threatening factor for this small population is a road investment planned in the future.
This work presents a list of localities for the following species: Anastrophyllum michauxii, Campylopus flexuosus, C. pyriformis, Diplophyllum obtusifolium, Fuscocephaloziopsis catenulata, Orthodicranum tauricum, Porella cordaeana and Ricciocarpos natans.
The paper presents the results of studies on bryophyte flora of the Reberce forest reserve located in the Przemyśl foothills. Thirty-three species of liverworts, 70 species and two varieties of mosses were found. Terrestrial (66 species) and epixylic (58) bryophytes formed the largest ecological groups in the reserve. Twenty-four protected species were also recorded, eight endangered bryophytes and six taxa considered as primeval forest species. The most interesting finds are: Bazzania trilobata, Buxbaumia viridis, Calypogeia suecica, Cephalozia catenulata, Frullania dilatata, Metzgeria conjugata, Nowellia curvifolia, Orthotrichum lyellii, O. stramineum, Trichocolea tomentella and Ulota crispa.
The results of bryological investigations from the “Boczki” nature reserve, located in Puszcza Romincka Forest, are presented. The reserve was established in 1974 for protection well preserved forest communities characteristic of the Romincka Primeval Forest. 154 bryophyte species were recorded – 37 liverworts and 117 mosses, including 37 unpublished species from the Puszcza Romincka Forest. In respect of frequency the main group make rare species – 29.2%, the least numerous were frequent – 21.4%. Terrestrial and epixylic habitats were the richest – refer 98 and 85 species respectively. Significant were groups of protected (47) and endangered (14) species. There is also a large share of bryophytes considered as primeval forest species – seven liverworts and 24 mosses, Antitrichia curtipendula and Zygodon rupestris among them.
