The Pressure of Grazing and its Impact Upon the Vegetation,atterns of habitat use, activity, feeding behaviour and diet. Each such usage exerts a certain pressure upon the vegetation. In this section I wish to try to pull together all the various uses of the Forest made by the different animals, in order to assess total impact on the vegetation.

Naturschutz in Bergbaufolgelandschaftenem. Grazing has always played an important part in the ecology of the Forest; in the past the deer populations for which the area was primarily set aside perhaps played the major role (populations were estimated at 8,000–9,000 animals during their peak).
