APPLICATION OF THE SYSTEM OF CRITERIA FOR ASSESSING FOREST COMMUNITIES FOR THE CONSERVATION VALUE OF PINE FORESTS (PINUS KOCHIANA) IN DAGHESTAN
ABDURAKHMANOVA Zagidat I.
For the first time, using the criteria system of nature conservation significance of plant communities developed by the Laboratory of Geobotany and Vegetation Protection of the Institute of Biology of the Ufa Scientific Center of the Russian Academy of Sciences, an assessment of communities of 12 associations of pine forests of Daghestan has been carried out. The assessment of nature conservation value shows that many communities of pine forests of Daghestan are relatively rich in species which require protection (rare species listed in the Red Book, relics and endemics); this can be a basis for organizing conservation. At present, information on the current state of the populations of these rare species is insufficient; there is still no accurate data on their numbers, vitality, nature and effectiveness of renewal. The need to protect these species dictates the need to protect the communities of Koch's pine, each of which contains several rare and endangered species. The floristic significance of the communities of Koch's pine is high. Of the 570 species of vascular plants in the Koch’s pine communities requiring protection have been identified; 9 of them are listed in the Red Book of Daghestan, 11 - the Red Book of Russia, 128 species are endemic, 107 - relics of various periods. According to the assessment, the pine forest communities currently do not have any protection, except for the Pinetum calamagrostidoso-hylocomiosum pine forests, located in the Upper Gunib Nature Park. Of great importance are the associations of Pinetum kochianae oxalidoso-hylocomiosum , Pinetum kochianae oxalidoso-hylocomiosum, Pinetum hylocomioso-vacciniosum , which include a large number of boreal element species, endemics and relics, several Red Book species and are probably originally indigenous. Undoubtedly, all these communities should be included in the list of rare plants and must be protected.
