Conflicts between human activities and the management and conservation of the biological diversity are becoming apparent in all European landscapes. Public support and acceptance of conservation measures seems urgent to reach national and international conservation goals. This project analyses the psychological factors behind public acceptance of biodiversity conservation measures. In an empirical study, perceptual and emotional responses to three types of broadleaf deciduous forests with different vegetation structure and species composition are studied. These responses, as measured by EEG and questionnaires, are related to acceptance of management and conservation measures for the biotopes.
