Abstract
The purpose of this research was an analysis of the impact of main climatic factors on tree growth and current treeline dynamics under the climate changes in the mountains of Western Tuva. Tree-ring width chronologies were built based on larch samples (Larix sibirica) of living trees from the upper timberline, the chronologies were compared, their statistics were estimated, and correlation with temperatures and precipitations were received. Correlations between chronologies and climatic factors revealed different climatic influences on radial growth along a north-south gradient in the study area. In conditions of sufficient moisture tree ring width correlates positively with average summer temperatures and negative with precipitations.
