Forests that are integrated into a big city cannot be compared with forests in the countryside. In the city the different forest functions do have another meaning than in the country. Recreation, protection against emmission and being an object of biological studies are - beside the economic function - important functions of the forests of Linz. For all these functions of the forests of Linz a sustainable forest management is necessary. So the sense of this study is to give a good information about the actual status of the forests and to make a proposal for a sustainable forestry where this is necessary. The ground informations at the beginning of the study were the biotope maps of Schanda/Lenglacher and the "ARGE für angewandte Naturschutzforschung und Vegetationsökologie" from 1989. The silvicultural survey in 1326 single biotopes encluded the following parameters: the actual forest community, the tree and the shrub species of each layer of the forest (secured and unsecured regeneration, middle layer, upper layer), the percentage of the cover of each layer, the phasic age, the game damage (especially browse impact), other damages and threats, the percentage of standing and lying deadwood, the naturalism of the forest, the speciescomination, the agecombination and the regeneration. By the analysis of these parameters the silvicultural planning for the forests and a catalogue of measures was derived. The catalogue of measure also encludes a proposal for hunting in the forests and for the restoration of the swamp forest-dynamic. Besides this a concept for steering the visitors of the nature conservation area "Traun-Donau-swamp forest" was developed.
