Despite a multitude of international and national level sustainability guidelines and principles the transfer into practice of natural resource management is still a challenge. Hence, the main objective of this work is to catalyse the transfer of meta-level SFM principles onto the level of forest practice. In paper (1), based on the Pan-European Operational Level Guidelines (PEOLG) of the Ministerial Conference on the Protection of Forests in Europe (MCPFE), a set of SFM indicators at the forest management unit level was developed by means of a Delphi survey addressing a large number of Austrian forest experts and stakeholders. Multi-criteria analysis (MCA) was introduced to support structuring and assessment within the indicator framework. MCA is set of methods designed inter alia (i) to take account of multiple, conflicting indicators, criteria or objectives, (ii) to involve stakeholders, their values and preferences, (iii) to prioritise and rank management alternatives and (iv) to support a comprehensible and transparent decision process in the SFM context. In paper (2) the Analytic Network Process (ANP), a network structuring MCA method, was introduced for the first time into SFM issues. This approach was compared to a hierarchical method and shows strong affinity to the holistic and systematic understanding of modern SFM. The ANP was utilized to extend the functionality of two internationally promoted indicator models, the Pressure-State-Response model (PSR) in paper (3) and the Driving Force-Pressure-State-Impact-Response model (DPSIR) in paper (4). Both indicator models were combined with the ANP (i) considering a forest management unit as the object system, (ii) interlinking the indicators in the network framework, and (iii) evaluating management strategies for their performances over time with regard to SFM.
