Abstract

The effects of the spring surface fire in 2009 were estimated in a 70-year-old pure pine stand in the forests of Kharkiv city’s green zone using dendrochronological methods (on the example of the State Enterprise «Zhovtneve Forest Economy»). After fire damage, there was a depression of radial increment of pine trees in subsequent years in addition to the deterioration of the trees. Adverse weather conditions contributed to the increment depression. Based on the deviation of the main meteorological indicators from the average multi-year temperature and precipitation values, the abnormality for weather conditions during the growing seasons of different years was calculated. In the pine stand damaged by a surface fire, the changes in radial increment were compared for groups of trees of similar thickness degree having different heights of scorch on the trunks among themselves and with the control. The features of the formation of layers of spring and summer wood in the damaged pine forest were evaluated in comparison with the main weather indicators in different months.
