In view of the generally bad economy and the socio-cultural background, however, it is unlikely that people could be convinced to reduce pastoral use drastically, at least not in the near future. From these examples it should become clear already that general statements on the role of animals as ecological agents cannot be expected, although there is an urgent need for action. To meet it, the animals’ role has always to be assessed with special regard to the specific local socio-cultural and economic conditions, thus going beyond a merely landscape-ecological approach.
