This paper investigates, through an actor-network theory perspective, how the recreation area Lövsta-Kyrkhamn-Riddersvik northwest of Stockholm has developed from being a dumping site into becoming a nature reserve. This investigation also tries to describe and explain which values that have been promoted in the area by the local voluntary associations and companies. Lövsta-Kyrkhamn-Riddersvik has been inhabited for more than 3000 years, originally with farming as the most important business. The area served as Stockholm’s waste disposal site from the late 1890’s and has today become an important area for recreational use. The actor- network theory perspective is used to identify different actors, both human and non-human, that has worked for the protection of the area and thus gained power over the decision-making.
