Study of coenopopulations of some endemic and rare species in Gusar district
Summary
On the basis of the monitoring conducted in Gusar district and analysis of the literature data, growth of 24 endemic species of the Caucasus, belonging to 23 genera and 17 families and 1 endemic of Azerbaijan (Rosa sosnonowskyi Chrshan.), as well as 51 rare and endangered species belonging to 47 genera and 30 families were determined. As a result of the study of natural coenopopulations (CP) of some endemic, rare and endangered species growing in forest and meadow coenosis of the study area it was revealed that according to “Δ -ω” classification: CP of Platanthera chlorantha is characterized as young, CP of Aquilegia olympica, Asyneuma campanuloides, Limodorum abortivum and Pyrethrum coccineum as mature, CP of Aconitum nasutum as aging, CP of Sorbus aucuparia as old, and CP of Galanthus caucasicus and Ophrys caucasica as transitional type. Phenological observations of some introduced rare species (G. caucasicus, P. chlorantha, L. abortivum, O. caucasica, Crocus speciosus, Ornithogalum ponticum, Himantoglossum formosum, Orchis purpurea and Dactylorhiza flavescens) showed that the growth and development of individuals of these species are positive, but compared to its natural conditions, there is a certain delay in its development periods (vegetation, flowering, fruiting).
