STRESZCZENIE
A new locality of Polystichum aculeatum was found in
2018 in the Błędzianka river valley in the Litewski Lake District (Warmia and Masuria Province), where
the species has not been recorded since the 19th century. The population consisted of 13 clumps on an
extremely steep slope in species-rich broadleaved forest of the Acer platanoides-Tilia cordata community within the recently proposed Czarcia Kępa Nature Reserve. In order to protect valuable broadleaved forest
with P. aculeatum and other rare species – including an abundant population of the rare Campanula latifolia
– the planned nature reserve should be established there.
