Like industry or agriculture also forestry can have major impacts on water bodies. This is a particular matter of concern in a country like Sweden, where wooded land accounts for 75% of the total land area. The application of clear felling, whole tree harvesting and nitrogen fertilisation for example promotes acidification of lakes and streams. Of course, there exist also many other influences of forest management on aquatic ecosystems. The first task of this report was to find out the most important forestry practices causing threats to Swedish waters. Based on the outcome of this research, current water-protective measures were identified and analysed. Information was gathered in a combination of literature study on the one hand and qualitative interviews with key persons on the other hand. The results of the study show that there exist many water-protective measures in Swedish forestry. They derive from different sources like the Forestry Act, the Environmental Code or information campaigns. Most water protective measures have high potentials. They are important tools for the conservation of aquatic ecosystems. Nevertheless, the complexity of regulations can also lead to confusion among forest owners. This is a major threat for the efficiency of water-protective measures in Swedish forestry.
