| Summary: | Aim. To determine the age structure and assess the current state of Fagus orientalis Lipsky in the Caucasian Ecoregion. Material and Methods. The material was collected in beech forests in different floristic districts of the Caucasian Ecoregion. The registration of individual specimens was carried out on 121 test sites, with a total area of 73925 m2. A total of 19936 individuals of Fagus orientalis were involved in the analysis. Each individual was assessed by condition and assigned to a certain age group.Results. The study of the age structure of Fagus orientalis in the beech forests of the Caucasian Ecoregion showed a similar pattern of distribution of age group participation in all the studied areas studied. The age spectra revealed are left‐sided and full‐membered where individuals of the pregenerative phase predominate. For all populations, in general, almost the same share of the contribution of individuals of germinal and virginal age groups was noted, amounting to about 50% in total. On average, there are 2906 individuals per 1 ha, of which 459 have reached the generative phase. The condition of individuals of the pre‐generative and generative phases across all the botanical areas of the Caucasian Ecoregion studied was estimated by us at 1.47 points.Conclusions. The study of the age structure of populations and the assessment of the condition of individuals allows us to assess the influence of certain abiotic and biotic factors. Low values of the proportion of postgenerative individuals are the result of anthropogenic load in easily accessible territories. Under the influence of processes of intra‐ and interspecific competition, the share of participation of virginal and postgenerative groups increases and is especially clearly observed in beech elfin‐woodlands. |
