Abstract

A model reconstruction of the potential forest cover of dark coniferous taiga on the Russian Plain, the Urals, and some territories of Western and Central Siberia is presented. The dot area of tallherb dark coniferous forests has been constructed based on 850 geobotanical releves (from the Database of the Center for Problems and Ecology and Productivity of Forests, Russian Academy of Sciences). The dot area of tallherb dark coniferous forests has been compared to that of Tilia cordata and contemporary zonality of the studied area. The ecotopes and ecological characteristics of the tallherb forests have been determined. Constant species of the tallherb forests have been revealed. Based on the literature data and the created database of herbaria labels, refined ranges of tallherb species were constructed. The importance of studying tallherb dark coniferous forests has been assessed to determine the origin of the dark coniferous taiga and select virgin forests for evaluating the main functions of the ecosystem.
