The stress effect of the solar UV-B radiation on the growth and productivity of trees is proposed to be taken into account during deforestation and plantation activities. The effect is estimated based on the prediction of natural variability of ozonosphere. The prediction is based on long-period trends of stratospheric ozone paleobehavior for the last 150-200 years. As a result, it became possible to reveal favorable and unfavorable periods for growth and productivity of coniferous trees in the region under study. In the framework of the problem, the information content of satellite monitoring data on the vegetation cover activity (series of the normalized difference vegetation index NDVI) has been treated. The results of the correlation analysis of time series of the total ozone content (TOC) and NDVI for coniferous forests are presented.
