Abstract
The particularities of the lichen coefficient LC (the ratio of lichens to vascular plants, or L : P-ratio) in different geographical regions of the Earth and different areas of Russia are determined on the basis of analysis of numerous quantitative estimations of lichen and vascular plant diversity. High values of LC in Arctic regions are caused by adverse conditions for growth of the vascular plants, while low LC values in plain regions with arid climate are caused by adverse influence of bioclimatic conditions on development of lichen flora. The mountains in temperate latitudes (especially near oceans) and tropics are optimal for forming rich and diverse lichen floras. Data on LC in different nature zones can be used for estimation of lichen species diversity, and to indicate some gaps in researches of regional lichen floras.
