Аннотация: Mixed conifer-broadleaved forests with tall herbs composed of Abies sibirica, Pinus sibirica and Populus tremula, also known as "Chern forests" in Russia, represent a separate class of subboreal (hemiboreal) ecosystems in the Altai-Sayan Ecoregion. Their structure is not that of boreal Siberian taiga, and resembles some features ofПоказать полностьюsubnemoral dark coniferous forests of the Far East. Recent studies by the authors confirm relict and original features of these Chern forest types, their synusial structure and ancient floristic links with Far Eastern mixed coniferousbroadleaved forests. On the other hand, the Chern forests may be classified as a part of unique rain-barrier boreal orobiome, which is represented only in perhumid bioclimatic provinces of the South Siberian mountains and is composed of a complex of altitudinal belts: mixed dark coniferous forests with a mix of broadleaved trees (Chern), perhumid dark taiga, and subalpine dark forests and woodlands. These forest types are important for bioclimatic classification and mapping of mountain vegetation.
