Distribution and condition of natural habitats of the proposed Natura 2000 area “Ostoja nad Bobrem”

The paper summarizes fieldwork which was carried out on the proposed Natura 2000 area called "Ostoja nad Bobrem", located in the south-wester Poland.
The research confirmed the presence of natural habitats appearing in Annex I to the Habitat Directive. Among them there are particularly important priority habitats such as: species-rich Nardus grasslands on siliceous substrates in mountain areas (and submountain areas in Continental Europe – *6230), Tilio-Acerion forests on
slopes screes and ravines (*9180) and alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae – *91E0).
