A Demographic Structure of Populations of <i>Salvia Lilacinocoerulea</i> Nevski, a Rare Species Endemic to the Western Pamir-Alay (Uzbekistan, Turkmenistan)

Salvia lilacinocoerulea Nevski (Lamiaceae) is an endemic to the Western Pamir-Alay mountain range. Usually it grows on eroded clay soils among sparse juniper forests in the middle mountain belt. Studied coenopopulations of S. lilacinocoerulea are normal, but are not complete. Coenopopulations self-maintenance is carried out by the seed of renewal. The characteristic spectrum of S. lilacinocoerulea coenopopulation is centered, with a peak in the middle-generative individuals. In most cases, specific developmental spectrum of coenopopulation does not coincide with the characteristic ones. The demography structure of mostly investigated coenopopulations is satisfactory. The population growing on the grey clay soil, on strongly eroded slope among sparse juniper woodland was evaluated as critical due to absence in ontogenetic spectrum young individuals and small percentage of generative plant as well.
