Dendrochronological researches of tree species after fire reaction in Central Yakutia

In the article the results of tree species radial increment reaction to the after fire dynamics growth conditions changing on the territory of Central Yakutia are given. Dendrochronological studies showed that after the forest fires the hydrothermal characteristic of permafrost changes, the depth of seasonally melting layer increases which have a big effect on the larch and pine tree growing. Using dendrochronological methods the reaction of tree species for such changing is shown.
