Ценопопуляции двух видов пальчатокоренника (Dactylorhiza Nevski, orchidaceae ) в условиях антропогенной нагрузки

Ecological characteristics of the habitat is given, common number, density and age structure of populations of two species of the genus Dactylorhiza Nevski (Orchidaceae) are defined in terms of strong anthropogenic stress. D. maculata and D. incarnata grow on horsetail motley-grass meadow; soil is clayey and peaty, with a weakly acidic and acidic reaction; the content of humus is low, area exposed to trampling domestic animals. The common number of plants in a small area is a few thousand individuals. The average density of plants was 26, maximum 79 plants per 1 sq.m. In the coenopopulations are present individuals of all age states. The spectra of age is right-hand. Ecological and phytocenotic conditions can be considered optimal for D. maculata and D. incarnata, despite the strong anthropogenic stress.
