Abstract: The research material for dendrochronological analysis was collected in forest area located in Utena Forest Enterprise. The objects of study were as follows: 40 year-old Vaccinium Pinetum one-layer stands, quality class – II. In two objects forest fires were in 2003 and in other two – 2006. Also, one object was selected as control where fire has not been observed. To estimate the influence made by fire to tree (Pinus sylvestris L.) radial increment, samples were taken ussing Pressler age borer in accordance with the methods for collecting experimental material of dendrochronological research work (Stravinskiene, 1994). To measure annual radial increment and estimate tree ring structure, the samples were examined by LINTAB tree-ring measurement system and TSAP computer programme. The COFECHA programm was used for analyzing obtained primary data. Using the COFECHA programme we performed cross-dating quality control. Annual tree-ring width series of asynchronous growth or lagged correlation were rechecked, corrected or eliminated from the next stages of the research with the master chronology approach. To determine impact of fire to stand growth conditions upon Pinus Sylvestris L. radial increment dendrochronological research work, dendrochronological scales of the stands with former observed fires and control stand was carried out. Well-defined decrease of radial increment was ascertained. Fire presence makes significant impact of annual radial increment dynamic after it’s emerge. Annual radial increment decrease is observed in time period of 2-6 years after fire damage
