Index of similarity

The floras of the two areas of ridge-ground pine forest (relevé; 1 and 2) are very similar. Though both possess only 18 species of vascular plants, there are many bryophyte and lichen species, particularly where the cryptogamic mat is undamaged. Both are progressively less similar to the ancient spruce forest (relevé: 3), the spruce forest of the buffer zone (4) and the seral birchwood (5). The normal spectrum taken from the world list has less than half the representation of hemicryptophytes and geophytes as that for the Fiby urskog reserve. The comparatively large representation of helophytes and hydrophytes in the reserve is, like that of so many Scandinavian forests, due to the vegetation of the lake and mires.
