Tkach O. Specific aspects of the development of pine stands damaged by ground fires in Volyn Polissia

Object – features of forest fires and postpyrogenic changes of pine forests; aim is to identify the features of the forest fires occurrence and postpyrogenic changes in the pine forests of Volyn Polissia; methods – forest mensurational, dendrochronological, forest pathological environmental and methods of mathematical-statistical analysis using modern information technologies; novelty – trends in forest fires have been established; age-related trend of forest litter formation and it combustion regimes have been established; changes in the pine forests of Volyn Polissia damaged by surface fires were studied; results – methodological approaches have been developed to assess the anomalous weather conditions, the dynamics of post-pyrogenic mortality and marketability of pine forests; it was found that fires in abnormally dry years are especially catastrophic, lethal levels of damage to pine forests by various types of heat spreading are revealed; preventive measures to minimize losses caused by forest fires in the pine forests of Volyn Polissia are proposed; scope of application – forestry.
