Description :
Introduction to vegetation structure and modifications of tree forms on border habitats of forests is followed by a description of geo-conditions in the Hercynian district. First prerequisite for border habitats is an extrem relief| soil and climate differenciate the vegetation of them. Rivers rocky valleys, rocks and rubble dumps on basaltic and phonolitic hills and rocky steep slopes in the Triasic hilly country are the most important border habitats of forests of this area. On not calcareous or calcareous soils on dependence of the climate one can find various complexes of vegetation. They contain bushlike forests, shrubs, forb fringes and xerothermic grasslands. The position of these complexes in the landscape and the relation to zonal vegetation are represented by many examples. Sociological, distributional and ecological conditions, structure and floristic combination of border forests and forb fringes are characterized.
