W obrębie trzech transektów przecinających doliny Noteci i Kanału Bydgoskiego wraz z ich krawędziami w okolicach Ślesina, Nakła nad Notecią i Bielaw, zajmujących łączną powierzchnię 25,11 km2 udokumentowano występowanie 889 taksonów roślin naczyniowych. Wśród nich tzw. gatunki „cenne", czyli gatunki chronione i uwzględnione na krajowych, regionalnych listach i lokalnie rzadkie stanowią 14,52%...
W oparciu o dostępną literaturę, dane niepublikowane i własne rozpoznania przedstawiono zróżnicowanie zbiorowisk z klasy Molinio-Arrhenathe-retea w regionie kujawsko-pomorskim oraz oceniono stan ich poznania. Zwrócono uwagę na rolę użytków zielonych w zachowaniu różnorodności biologicznej krajobrazu rolniczego na poziomie roślinności i flory ze szczególnym uwzględnieniem "najcenniejszych"...
180 vascular plant taxa are found in the Las Mariański forest reserve, including 21 protected and endangered species. In the last 40 years, the total number of species has increased, including the number of anthropophytes. Spontaneous forest succession has taken place on previously open terrain, resulting in a slight increase in the share of species typical for the class Querco-Fagetea and a 9% decrease...
