In the Rare and Endagered Plants Section, plants protected by law and listed in the Polish Red Data Book of Plants as well as in regional lists of threatened species are presented. Collecting these species and their conservative ex situ cultivation is one of a part of the many activities which are performed in order to protect biodiversity. Noteworthy is also the educational value of exhibitions and the popularization of the native flora and the idea of its protection among the general public. The protected and endangered species are also presented in other sections. To facilitate their identification in the Garden, they are all marked with red labels.
