| Summary: | Tree-ring width chronologies were built for Siberian stone pine, Siberian larch and Siberian spruce in the forest limit and the upper forest belt of the Seminsky Range. The chronologies were compared, their synchrony and statistics were estimated, and correlation with temperatures and precipitations were received. In the forest limit the growth responses to temperature and precipitations are similar in pine and large. Tree ring width correlates positively with May, June and July temperatures and negatively with May precipitations. In the upper forest belt the responses of the trees are different because of degree of density, crown closure, and phytocoenological conditions are increased from the forest limit to the upper forest belt. The ring width and June temperatures are positively correlated in larch. In pine and spruce the correlation is positive with May and July temperatures and negative with August precipitation. The results are evidence of paramount importance of temperature and precipitation in forest trees of Seminsky Range. |
