Description

Productivity was determined for an old-growth boreal forest (age 260 years) at the Kuusamo site for the period 1967 to 1971. The research was carried out as part of the International Biological Program (IBP), and results contributed toward contemporary work on modeling forest ecosystem processes. Picea abies (sometimes described incorrectly as Picea excelsa) dominates the upper storey, and shrubs (Vaccinium myrtillus, Vaccinium vitis-idaea) and mosses (Hylocomium splendens, Pleurozium schreberi) dominate the open spaces between the trees.

The Kuusamo study site (66.37 N 29.32 E) is located at the Oulanka Biological Station in Oulanka National Park, Finland, approximately 60 km north of the town of Kuusamo. This area has a mean annual temperature of 0 C and an annual amplitude of 28-29 C for mean monthly temperatures. The mean annual precipitation of 500 mm and low overall temperatures result in saturated or moist soil conditions for most of the year.

Total net primary productivity (NPP) for this site was estimated to be 441 g/m2/yr (421 g/m2/yr above-ground, 20 g/m2/yr below-ground). Further information for this site is available on-line in the IBP Woodlands Data Set maintained by the ORNL DAAC.
