Abstract
The results of the study of Cladonia lichen post-fire growth rate dynamics in different zonal units of West Siberia were presented. Relative growth rate of lichens in forest-tundra and taiga zones was assessed with regard to the pyrogenic factor. The growth rate varied from 1.2 mm/year at the early stage of progressive succession to 11.9 mm/year at the stage with dense lichen cover. The variations in lichen growth rate at different stages of recovery were observed in southern and middle taiga communities. In open forests and forest–tundra communities of northern regions the growth rate of lichens was not characterized by significant changes.
