Analysis of the flora of communities with the participation of Juniperus excelsa subsp. polycarpos c. Koch Foothill Dagestan
Abstract
The paper presents the results of the analysis of plant communities of Piedmont Dagestan with the participation species of the Red Book Juniperus excelsa subsp. polycarpos (C. Koch) Takht. The taxonomic and biomorphological structure of the flora was considered, a geographical analysis was carried out, endemic, relict and protected species identified in the Red Books of Russia and the Republic of Dagestan were identified.
239 species of higher plants belonging to 163 genus and 58 families have been identified, the spectrum of families (As-Po-Ro) characteristic of the xerophytic-steppe florocenotic complex of the Central European type has been determined. The biomorphological spectrum of juniper open woodlands of Piedmont Dagestan belongs to the hemicryptophyte-terophytic type, corresponding generally to the arid flora. The high proportion of relicts and endemics (21.3 and 21.5% of the total number of species, respectively) in the composition of juniper open woodlands indicates their relict nature, significant peculiar and role autochthonous processes in the formation of the juniper forests of Piedmont Dagestan.
Analysis of the structure of the flora of juniper open woodlands of Piedmont Dagestan shows its cross-border position at the junction of the boreal and ancient Mediterranean kingdom of the Holarctic, in the zone of contact of the Euro-Siberian and Iranian-Turanian regions, characteristic generally and for the Caucasus with a deeper and ancient connection with the Iranian-Turanian flora.
