Orchids (Orchidaceae juss.) at especially protected natural territories of Yaroslavl oblast

In study information about orchid habitats on specially protected nature areas of Yaroslavl region and their presence in certain ecotopes and phytocenoses was generalized and systemized. It is shown what the greatest worth as storages of orchids have Federal status protected territories. This is the Darwin state strict nature biosphere reserve (14 species) and Plescheevo lake national park (20 species). Also protected areas of regional status have a significant meaning of the conservation of species diversity of orchids - wildlife refuges (20 species) and nature monuments (19 species). The wildlife refuges «Kuchenevskiy» (15 species) and «Wetland Karachunovo» (14 species), nature monument - «Wetland Zokino» (17 species) differ in a rich flora of orchids. The three groups of species of Orchidaceae occurrence in protected areas were created: the first is identified more than 50% of the territories ( Dactylorhiza maculata, D. incarnata, D. traunsteineri, Platanthera bifolia, Listera ovata ); the second identified by less than 5% of the area ( Coeloglossum viride, Dactylorhiza cruenta, D. russowii, Epipogium aphyllum, Gymnadenia odoratissima, Ophrys insectifera, Orchis militaris, Platanthera chlorantha ); the third is not identified ( Cypripedium guttatum, Dactylorhiza baltica, Epipactis atrorubens, Neottianthe cucullata ). It is expected to a correlation of obtained data and a presence upon the protected areas of ecotopes needed for different species of orchids, their biology and ecology, the nature and intensity of effects on ecosystems, different degrees of knowledge of the flora of specific protected areas.
