Regular fires have significant influence on tundra and taiga ecosystems. Features of
vegetation recovery in these territories are determined by climatic conditions and degree of
disturbance. We sought to assess impacts of fire on lichen communities in West Siberia,
Russia.
The goal of our study is to present an original assessment of lichen cover during postfire
recovery in latitudinal gradient from forest-tundra to taiga zones.
Key plots were located into post-fire community of tundra and forest sites in foresttundra
zone and also in three subzones of taiga: northern light forest, middle and southern
boreal forests. We sampled a total of 76 plots with a 100 m 2 size.
We had several primary trends in this study: a) species diversity and richness of postfire
lichen communities in different zones; b) analysis of ecological and geographical
structure of biota throughout succession stage; c) indicator species of post-fire communities;
d) dynamics of lichen mat structure and phytomass.
Lichen mat conditions and successional status of different stages of post-fire recovery
into study zones were indicated using occurrence, abundance, total and average cover of both
individual species and their morphological groups. Indicator species for uneven-aged
pyrogenic communities and four stages of post-fire lichen cover were defined from analysis of
these parameters. Differences of height, age and growth of Cladonia species confirmed
validity of defining stages.
Biomass of lichen mat and its structure in multiple-aged stage post-fire communities
depended on zonal conditions of study areas and dynamics of other parameters which
characterized lichen cover.

Three mountain ranges of Polish Western Carpathians (Gorce Mts, Babia Góra Massif
and Tatra Mts) were explored in the period 2008–2010 to investigate the diversity of
lichenized and lichenicolous fungi occupying dead spruce trees and snags in natural forests
destroyed by bark beetle Ips typographus. 400 objects in strictly protected areas of national
parks have been studied, representing the type of simple, group and large-scale destruction of
stands. 161 species of fungi (144 on wood and 101 on bark remnants) were found; 140
lichenized, 20 lichenicolous and commonly occurring non-lichenized Mycocalicium subtile.
