There are only few studies of Russian Far East climate; moreover, dendrochronological studies in the continental part of this huge territory are absent. Meanwhile, most of tree species form northeastern China, Korean peninsula and Japan are presented in this region. In addition, the Russian Far East is the northern boundary of some tree species ranges and this significantly increases their climatic sensitivity. Also, some forests in the Russian Far Eastern have not been subjected to human activity for the last 2000-4000 years. Finally, the southern part of the Russian Far East is sensitive to global climatic changes as it is under the influence of cold air flow from northeastern Asia during the winter and summer monsoons. All the factors create favorable conditions for dendroclimatic studies. Mixed forests with Korean pine (Pinus koraiensis Siebold et Zucc.) are the main vegetation type Russian Far East. This area is the northeastern limit of the Korean pine-broadleaved forests range, which are also found in northeastern China, on the Korean peninsula, and in Japan. The Sikhote-Alin mountains is one of the few places where significant areas of old-growth Korean pine-broadleaved forest remain. The territory of Russian Far East is characterized by a monsoon climate which is determined by the interaction of the Pacific Ocean and the Siberian anticyclone. So, the radial growth of Korean pine in the study region is mainly limited by the pre-growth autumn-winter season temperatures and spring-to-early summer precipitation. Using the tree-ring width of Pinus koraiensis, we reconstructed the mean minimum temperature of the previous August-December for the southern part of Sikhote-Alin Mountain Range, northeastern Asia, Russia, for the past 486 years. Also, we reconstructed April–June precipitation for the southern, central, and northern Sikhote-Alin Mountain Range for the past 300 years. So, we obtained the first climate reconstructions for this region, and for the first time for northeast Asia, we present a reconstruction with a length exceeding 486 years. The results of our research are important for studying the climatic processes that have occurred in this region and northeastern Asia and for situating them within the scope of global climatic change.
