Phytocenoses found in grassy mountain-meadow soils in the subalpine zone of Talish

Abstract

Subalpine meadow vegetation of Talish highlands has been spread over the subalpine zone of Lankaran highlands at lawny mountain-meadow soils at the height of 1800 m to 2500 m above sea level. During the carried out ecological-geobotanical researches, it has been determined wheat-grassy different-grassy stepped subalpine meadow, different grassy-wheat grassy subalpine step meadow, bushy- different grassy- wheat grassy subalpine step meadow formation classes, 5 formation groups and 11 associations. In parallel with the study of type composition and structure of phytocenosis found in the area of investigation, it has been also determined endemic species, productivity of formations, and intensification of degradation at soil-plant coverage of some lawny subalpine meadows, decrease in abundance and productivity of forage crop. Currently, for the purpose of the improvement of natural phytocenosis productivity, crop quality, protection of their genetic reserve and landscapes, as well as the vegetation study for solution of protection problems on the base of scientific means is of a great importance.
