The Reconstruction of Gypsy Moth Outbreaks on the Zilair Plateau by Oak-Trees Radial Growth Analysis

Abstract

For the last 200 years for territory of the Zilair plateau (Southern Ural Mountains) on the basis of the analysis of an increment of late wood of common oak (Quercus robur L.) reconstruction of strong damages of leaves of an oak by gypsy moth (Limantria dispar L.) was made. It is shown that during gypsy moth outbreaks, as a rule, in the first year of outbreak the oak forests located in a southern part of a plateau were damaged. For the second and third years of outbreak strong damages of an oak were displaced in northern direction.
