Forest management measures are carried out only a few times during the life cycle of a forest. Depending on the tree species composition and geographic location, the cycle varies from 60 to 120 years. In some cases, management results in increased loads of nutrients and suspended solids, especially in headwaters. Water protection measures can reduce such loads considerably. The goal of the EU Water Framework Directive, which in Finland is implemented under the Act on the Organisation of Water Management, is to achieve a good status of waters in the Member States by the year 2015. National aims and measures are defined in Regional Water Management Plans.
