Abstract
The early stages and the important species in the re-colonization of wet and dry areas in a lumbered pine-wood are taken up in detail, accompanied by diagrams of succession and quadrat maps. Pteridium aquilinum, Epilobium angustifolium, Calluna vulgaris, Betula alba. and B. pubescens characterize the phases on dry ground, Pinus silvestris would follow naturally, but it is to be planted. On the damp sites, tussock grassland of Molinia caerulea rapidly developed and is being succeeded in turn by birch scrub and either mixed woods or pine. The very wet areas had Sphagnum and Juncus (especially J. effusus and J. conglomeratus) running into Molinia. Thorough burning brought mosses (Poly-trichum, Ceratodon purpureus, and Funaria) and Epilobium angustifolium into the early stages. Ruderal vegetation and that of pine stumps also receive consideration.
