XVI International Botanical Congess
Vegetation developing was analysed in well-drained Scots pine forests in the Kola peninsula burned at various time. There was a difference in correlations between coverages of species and different characteristics of sites in forests burned 40-60 and 90-210 years ago. Correlation between the cover of Vaccinium myrtillus and thickness of forest floor averaged respectively r=0.74*** and r=0.23, , correlation between the cover of Ledum palustre and share of lichens in moss-lichen layer averaged r=0.07 and r=0.57** respectively. Highest correlation was found between the total cover of the dwarf-shrubs and the share of lichens in moss-lichen layer (r=0.82***) in both samples.
