Species richness of mosses, fungi and vascular plants on coarse woody debris of beech in the Flemish forest reserve 'Kersselaersplayn' (Zoniënwoud)

Strict Forest Reserves can play an important ro le in the conservation and development of botanical richness in forests. Especially the high amount of dead wood, composed of all dimensional classes and decomposition stages, performs as a suitable substrate for often specialized species of vascular plants, fungi and mosses. An international research programme was conceived to analyse this botanical richness, more specifically on dead wood of beech. In this ppaper some general prliminary results for the reserach site int he Zoniën-forest are presented.
