Dynamics of ground vegetation after surface fires in Scots pine forests (Nignee Priangarie)

Post-fire succession of ground vegetation is a complex phenomenon which depends on a combination of factors (fire severity, depth of burn and prefire vegetation). Surface fires had a clear effect in initial succession in study area and it clearly had an impact on species diversity, percentage cover and biomass of ground vegetation. Fires of highand moderate severity changed of horizontal structure and dominants of ground vegetation. Lichens and mosses were completely destroyed by fires of highand moderate severity. There is a positive trend of prefire microgroups recovery after fires of lowseverity.
