Forest and its waters are closely connected and dependent on each other. This means that management activities in the forest affect water quality. To be able to take as effective consideration as possible it is important to have guidelines that can guide actions to areas and activities with the highest effect at the lowest cost. Blue target classification is a classification system for water environments developed by WWF in cooperation with Swedish forest companies. The system has been evaluated and is considered having good potential for improving water quality consideration within forestry. But for the classification system to be able to be utilised on large scale, and to be as effective as possible there is a need for easy to use methods that can connect a stream classification with adjacent forest’s planning. Heureka is the leading forest planning system in Sweden, and we have developed a tool within Heureka that can do just that.
