Review of the state of populations of Neottianthe cucullata (L.) Schlechter in various regions of the Russian Federation

Abstract

Many members of the Orhidaceae family are rare plants. One of the effective ways to preserve these speciesis to include them in the Red Book and give them a certain status of rarity. Neottianthe cucullata has a wide species rangein the Russian Federation. This species is found in almost all regions located in the temperate zone. Neottianthe cucullatais included in the Red Book of the Russian Federation and, accordingly, is protected in 48 regions of Russia. The speciesgrows mainly in coniferous and mixed forests, so the main threat to it is the increasing rate of logging. Disturbance of soilcover and changes in environmental conditions are limiting factors. However, the analysis showed that the state of populations in different regions is very different. In the European part, where the pressure on forest resources is very high,Neottianthe cucullata has a status ranging from «probably extinct» to «very rare». In some cases, reliable information is notavailable. On the territory of Siberia, the species belongs to category 3 – rare. On the territory of the Republic of Buryatia, it belongs to category 7 – out of danger. Most often, the populations of Neottianthe cucullata are well studied and protected in nature reserves and sanctuaries. In a number of regions, there is no information on the state of local populations.
