Abstract
Cores of Scots pine growing in northern taiga on the northern limit of distribution in lichen pine forests in the Pechora River basin are collected with purpose to reveal most suitable for climatic reconstructions tree-ring parameters. Tree-ring width has a weak mixed signal of temperature and precipitations of previous and current years and, therefore, cannot be used for reconstruction. Maximum optical density has shown a very perspective temperature signal for reconstruction in area under study. Northern island pine forests have stronger signal, in comparison with the pine forests growing in 100 km to the south, in a zone of continuous pine forest. Reconstruction of June–August temperature for the last 200 years is executed for the first time. The obtained data have correlated with the reconstruction by chronologies of the maximal density of pine from Fennoskandia and Eurasia.
