History of disappearance of twinflower Linnaea borealis L. in forest complexes near Rogów
Linnea borealis L. is a postglacial relict in Poland, where it occurs at the edge of its southern range. It is a moderately heliotropic species, associated with coniferous forests. The aim of this study was to collect, analyse and summarise data on the history of its disappearance in forests complexes near Rogów (central Poland). We reviewed research papers as well as unpublished materials, photos and herbarium specimens, archived oral information and our own field observations from the years 1999–2021. Out of seven known original locations from the years 1930–1999, none endured to the present. Despite active protection (including reintroduction) and the foundation of a nature reserve, twinflower plants were not preserved, even in ex situ conditions. The main reasons for its disappearance were habitat changes due to regeneration of plant communities, eutrophication, climate change, and the spreading of alien species. As a result of the ongoing changes in the forest community, the twinflower was shaded and not able to compete with more vigorously growing species.
