Мониторинг состояния популяций редких видов растений болот
The paper is dedicated to the modern estate of Orchidaceae species occurring on Karelian mires, particularly on the example of Marsh Helleborine (Epipactis palustris) populations observed on permanent plots. The species is found to form full – spectra populations mainly in the communities regarded as Equisetum palustre – Sphagnum warnstorfii associations. These populations are quite sustainable resuming by vegetative reproduction.
