✦ Synopsis

General circulation models indicate substantial CO 2 warming in high latitudes. In these regions, which include the boreal coniferous forests, the activity of ecosystems is largely controlled by temperature. The effective temperature sum (degree-days) is used in this stud), for describing the regional variability in the productivity of boreal ecosystems. Although the concept is simple, it takes into account two basic factors: the length of the growing season and the day-to-day level of activity of the ecosystem. This study examines which areas in the boreal coniferous forests would be most sensitive to a possible climatic warming. The data usedin the study are for Finland.

A regression is estimated between regional forest gro~,th rate and effective temperature sum. A climatic warming ls assumed and the
