A dendrochronological analysis is made of wood samples of Siberian larch (Larix sibirica Ledeb.) from 33 areas situated in the mountains of Southwestern Tuva and Northwestern Mongolia. The analysis provided three regional chronologies, revealed spatiotemporal characteristics of the growth dynamics, specifically periods of increased and decreased increment, and cycles of a different duration. Statistical analysis of tree-ring chronologies gives evidence for a strong external (climatic) effect on the growth.
