Human activities have a significant role in the escalating loss of the global biodiversity. Approximately 10 percent of regional plant and animal species are threatened in Sweden, mainly by modern practices in agriculture, forestry and fisheries. People in Sweden are concerned about the disappearance of plants, animals, and wildlife habitats, and express a great concern for biodiversity conservation. Previous research show that a favourable attitude and a strong personal norm towards biodiversity conservation are significant predictors of public intention to support conservation of local biotopes. However, the public seem to have very vague ideas of what measures might be relevant to protect the local biodiversity. People may therefore respond negatively to those interventions introduced by environmental managers in forest areas. Although some forest owners have introduced conservation measures on their land, many still seem hesitant towards new approaches in forest management. Based on Value-Belief-Norm (VBN) Theory, the present study aims to analyse psychological antecedents of public acceptance regarding policies for local biodiversity conservation of broad-leaf forests. It is asked i) to what extent public acceptance of biodiversity conservation policies can be explained by the VBNtheory and, ii) if the psychological antecedents of acceptance of biodiversity conservation policies may differ between landowners, members of an outdoor organisation and local residents. In a first stage of the empirical work environmental managers at the Swedish Forest Agency and the County Administrative Board were asked to list appropriate conservation policies for broad leaf forests. Forty-five policies representing a wide range of strategies were chosen and categorised as ecological, financial/administrative and social policies. At the second stage the policies were written on cards and approx 120 participants (including forest owners, members of an outdoor organisation and local residents) individually sorted the policies for acceptance by means of the Q-sort method. Moreover they responded to a questionnaire covering the constructs of the VBN-theory. The paper will present statistical results concerning the relation between the VBNconstructs and acceptance of the three categories of polices, and possible differences between the three groups of participants will be analysed. The results will give and idea of which conservation measures may, and which may not, be controversial. Environmental managers will get an idea of what conservation measures are perceived as acceptable in broad-leaf in different user groups, and the different user groups will get a deeper understanding of each other’s needs and preferences. The results will further be discussed in the context of public participation in local biodiversity conservation.
