Agrarwirtschaftlich bedingte Vegetationsbereicherung und -verarmung in historischer Sicht

Abstract

By means of ecological interpretation of archaeobotanical data, the origin and development of anthropo-zoogenous vegetation from the beginning of human interference at a turning point of the mesolithic to the neolithic period up to the development of a modern agricultural landscape are described. The ecological changes during the transformation of natural woodlands into cultural landscape with its specific variety of anthropogenic biotopes are discussed. Four important periods are distinguished: fint, a primitive kind of field grass farming, lasting many thousands of years until the Middle Ages; second, the socalled «tree field farming» resp. a farming on plaggen soils in the Pleistocene landscapes
