Dynamics of plant species number in postpyrogenic phytocoenoses of the Kerzhensky Reserve

An overview of changes in the herb-shrub layer number of species on permanent sample plots established in the Kerzhensky Reserve after the wildfires of 2010 is provided. It is shown that the nature of the change in this indicator is influenced by both the type of fire and the shape of the mesorelief to which the permanent sample plot is confined. The presence of maxima and minima in the number of species was noted. The similarity in the type of changes in the number of species for areas with crown and intense ground fires is shown.
