Influence of anthropogenous loading on a condition of orchid's populations

The ecological characteristic of a habitat is given, the general number, density, age structure of populations of two species of genus Dactylorhiza Nevski (Orchidaceae). Displacement of maximum of an age spectrum to the right, towards the elder age groups is established. This occurs in the conditions of strong anthropogenous loading. Despite it, good condition of the populations, growing in optimum for them ecologophytocenological conditions, is marked.
