Entwicklung eines Indikatorenkatalogs zur Evaluierung einer nachhaltigen Waldbewirtschaftung auf betrieblicher Ebene | Development of an indicator catalogue for the evaluation of sustainable forest management at the forestry unit level

The Paneuropean Operational Level Guidelines for Sustainable Forest Management (PEOLG) were adopted in 1998 by 37 signatory states and the EU in the wake of the 2nd Ministerial Conference on the Protection of Forests in Europe in Lisbon. These recommendations provide a limited insight on operational definitions of mode, extent and time scale of valuable measures in forest management and planning. In this paper a set of criteria and indicators at forest management unit level is proposed by means of a Pressure-State-Response (PSR) model. The demands for the development of the indicator set, the adapted PSR approach and the methodogy of the Delphi survey are demonstrated. The paper concludes with a discussion of experiences gained within the process of the development and the implications for the evaluation of sustainable forest management at forest management unit level.
