Abstract
At the upper (forests near the high altitudinal tundra) and lower (forests near the Kuraisky steppe) limits of Siberian larch ( Larix sibirica Ledeb.) on the Severo-Chuisky Range (the Altai Mointains) the age structure of larch stands was described and the correlations between tree ring width chronologies and month temperature and precipitation sequences were analyzed. The new larch generations appeared during the century and decadal periods of temperature rise.
