Аннотация: Reconstruction of prehistoric forests can be based on restoring the areas of key species of plants and animals in those still preserved in refugiua which include tall herb forests. The main characteristic of unique boreal tall herb spruce-fir forests (association of Aconito septentrionalis - Piceetum obovatae) is presented in comparison with green moss spruce-fir forests (Eu-Piceetum abietis) that dominate in the taiga zone. Using the example of tall herb forests in the Pechora-Ilych Nature Reserve, we identified the following signs of intact forests of the Northern Eurasia: high diversity of vascular plant and moss species; full set of microsites connected with a tree-falls, well-defined gap-mosaic; diversity of ecological-coenotic groups; uneven-aged structure of tree species populations; fertile soil and rich soil biota; presence of broad-leaved forest markers such as ephemeroids (Corydalis solida, Anemone spp., Gagea spp., etc.); presence of broad-leaved tree species in paleo-spectra. The northern dark coniferous forests may also be regarded as historic refugiuabecause they were less disturbed by humans and probably less exposed to fire. Such model reconstructions will form the basis for developingmethods for restoring the pre-anthropogenic dark coniferous (taiga) forests of Northern Eurasia.
