National Park (Thuringia) : first results on flora and
vegetation in stands with contrasting tree species diversity
(2006) - A floristic description is presented of the study sites
of the Research Training Group “The role of biodi-versity for
biogeochemical cycles and biotic interactions in temperate
deciduous forests”. To investi-gate different aspects of plant
biodiversity in Hainich National Park (Thuringia), deciduous
forest stands with low, medium and high canopy tree species
diversity were compared. The results of species richness and
forest communities show that the research sites are
characterised by a typical central European forest flora.
Greater vascular plant species richness occurs with higher
diversity of tree species. Six of altogether twelve research
sites are assigned to the beech forest alliance (Galioodorati-
Fagion), the second half belongs to the oak-hornbeam forest
alliance (Carpinionbetuli). Suballiances within the Galioodorat
