Monitoring of populations of Dactylorhiza fuchsii (Druce) Soo in the South Ural reserve

Monitoring of the condition of the cenopopulations of Dactylorhiza fuchsii was carried out in the South Ural Nature Reserve. The article presents the results of monitoring the state of four populations. Population (morphological variability, abundance, density, age spectrum, index of individual optimum, recovery index) and vitalite characteristics were studied. A distinction was made between mountain-meadow and forest populations according to demographic and morphological characteristics. Phytocenotic and weather factors affect the habitus of plants, the number of individuals, the ratio of age groups in populations. The age spectra of the investigated populations are full-term, right-sided, with a predominance of generative individuals. In the reserve species populations are in satisfactory condition. The article gives a comparative analysis of the state of D. fuchsii populations in other natural reserves of the Republic of Bashkortostan.
