Abstract:Interpretations of the concept of sustainability vary substantially in relation to forests and their management, and they are usually present in conflicts about forest use. In this article, we consider underlying interests relating to conflicts of forest use as a given. Our aim is therefore not to reveal those interests, but rather to explore understandings of sustainability hiding behind them-sustainability frames. To this end, we use frame theory to investigate the following research question: How are different sustainability frames of interest groups reflected in a forest use conflict situation in Germany? The energy wood conflict serves as the example for our research, as it is currently the most prominent forest management conflict in Germany. Using 12 stakeholder interviews within three interest groups as the empirical data basis, it becomes clear that sustainability understandings reflect particular positionings in conflicts, or vice versa. In the energy wood conflict, the classic dichotomy between forestry and conservation groups becomes a trichotomy in which the forestry group splits into an interest group that profits from energy wood production and one that competes with it. We suggest that sustainability understandings do not represent worldviews that guide how actors understand conflicts, but rather that they are shaped according to actors' particular interests in conflicts.
