Dendroclimatology in Kazakhstan

We have reviewed 43 studies related to dendroclimatology in Kazakhstan, and additionally 13 studies related to other subfields of dendrochronology, which have been published during the past 40 years. This review also includes studies published in Russian, Kazakh, German and Chinese languages, which are not easily accessible to international researchers.Dendroclimatic studies in Kazakhstan began back in the days of the Soviet Union and were actively conducted in the southern and northern parts of the country. With the collapse of the Soviet Union dendroclimatic studies stopped and resumed only 15-20 years later. Within the last 5 years, the intensity and quality of dendroclimatic studies increased significantly. Several research groups have investigated climate-growth relationships of Scots pine, Silver birch, Siberian larch, Siever’s apple and Schrenk spruce. Schrenk spruce was the most widely studied of these species, and several climatic reconstructions have been published based off their climate-growth relationships. Results of most studies on Schrenk spruce demonstrated good consistency, allowing the general patterns of climate-growth relationships to be accurately traced. Unfortunately, studies on other tree species have either lower level or represented just by one or two studies. It would therefore be premature to make any generalizations on these species at the current stage.We conclude that there is a good potential and good base for continuing dendroclimatic studies in Kazakhstan. There is a need to close several research gaps which limit our knowledge, such as chronologies’ length, application of new methods, species composition and spatial coverage. Closing these gaps let us significantly improve the dendrochronological network of Kazakhstan and provide important data for further hydrological and climate studies in Kazakhstan.
