Abstract—The effect of increased ambient temperature on the vertical, radial, and volume increments of Scots
pine (Pinus sylvestris L.) trees has been studied in the zone of thermal impact from a burning petroleum gas
flare. Regular age-dependent changes in the pattern of increment dependence on the distance from the flare and
ambient temperature have been revealed. The mechanisms of these changes are explained. It is concluded that
an increase in ambient temperature by 1.0–1.5°C has a favorable effect on the dynamics of Scots pine growth.
