Abstract:The structure of dark conifer forests in the lower reaches of the Bol’shaya Porozhnyaya River is described. Ordination of corresponding communities has been performed, and their ecological and ecocenotic characteristics and species structure have been analyzed. On this basis, a typological scheme of the forests has been constructed following the method by L.B. Zaugol’nova. The identified sections and variants of communities within the true moss and tall herb sections are described. Successive change of leading ecological factors in the hierarchical series of communities, from sections to variants, is demonstrated.
