The paper presents the results of the research of local population of Anacamptis morio (L.) R. M. Bateman on the territory of the Left-Bank Ukraine. The size of this population was estimated at about 250-300 thousand individuals. The average density of individuals per 1 m2 is 12, while in terms of age structure, dominate individuals in the generative stage (70- 75%). A. morio inhabits fresh, forest-meadow biotopes. Its populations are found in fresh eutrophic and moist mesotrophic meadows and in coastal floodplain forests. This species is a part of vegetation of the KoelerioCorynephoretea and Molinio Arrhenatheretea classes. Considering the characteristics of the investigated A. morio population and its habitat we assert that the studied territory is unique, valuable and perspective for the creation of a nature reserve.
