Canopy LAI has been found to differ considerably depending on both dominant tree species and stand age. From among the species examined spruce exhibited the highest LAI amounting to 10.0 m2 m-2, where other species had much lower LAI-s (within a range 1.6-6.3 m2 m-2). Canopy LAI increased rapidly in young stands attained a peak at approximately age 20 and decreased slowly thereafter. It has been revealed that projected leaf area of an individual tree increases linearly as the tree grows older.
