Abstract
Purpose. The study of pre- and after the fire of pine forest stands forest steppe Harkivschyny. Methods. Dendrochronological. Results. Dynamics of results of dendroclimatic and dendroindication researches of pine stands on three permanent research plots damaged by fires in 2011. Trees that have good sanitary state and dominant trees restore the tree radial growth in 2 -3 years, at the same time trees in most damaged stand where height of deposit on tree stems are 3.87, didn’t revive the radial growth still. Significant relationships between defoliation and the radial growth for 2013 for second research plot (height of deposit on tree stem is 1,87 м) When the radial growth start to revive. This regression model was described by curves of third degree. Conclusions. It was found that less fire damaged trees that have the best sanitary conditions and are predominant, restored radial growth for 2 - 3 years.
