Phytodiversity of forest ecosystems of Ismayilli and Gabala districts
Summary
Based on the results of the monitoring carried out in the forest massifs of Ismayilli and Gabala districts, 162 taxa belonging to 55 families and 311 genera were recorded, of which 1 species is Azerbaijani, 13 are endemic to the Caucasus, and 16 are rare. According to the number of species, Rosaceae Juss., Asteraceae Giseke, Orchidaceae Juss., Poaceae Barnhart (with 11- 18 species) families are dominant. As a result of the biomorphological analysis, it was determined that herbaceous plants are the majority (73.5%), and the share of woody plants is 26.5%.The ontogenetic and demographic structure of the coenopopulations of 3 rare taxa (Galanthus alpinus var. alpinus (CP 1, CP 2), Orchis purpurea (CP 3), Ophrys oestrifera (CP 4) in different altitude zones was studied, based on the Δ and ω indices, CP 1 and CP 3 are young, while CP 2 and CP 4 are transitional. The forest vegetation of the districts includes 2 formation classes (mixed dark mountain forests, broad-leaved mountain forests), 7 formation groups, 9 formations, 24 association groups and 26 associations. According to the phytocenotic status of 25 trees and shrubs in forest communities, Quercus iberica, Carpinus betulus and Fagus orientalis species are edificators in both districts. According to the vitality indices of forest massifs, forests in Gabala district are healthier, but tend to weaken (81%), while in Ismayilli district, forests are assessed as weakened (71-56%).
