The effect of severe ground frost on Scots pine (Pinus sylvestris) trees in northern Finland and implications for palaeoclimate reconstruction
A severe frost event in the winter of 1986/1987 that resulted in widespread defoliation in northern Finland was used to test the influence of such growth disturbances on tree ring parameters commonly used for palaeoclimate reconstruction. In mature pine trees there was no effect on ring widths, late...
