The relationships between human use of forest, natural ecosystem dynamics, biodiversity, ecosystem function, and long-term change of forest ecosystems are complex and occur at different spatial- and temporal scales. Analyses of such complex relationships must be focused and at the same time require expertise from several disciplines. The approach entails multi-disciplinary modelling involving forest ecology, forest history, archaeology, quantitative palaeoecology, population biology, economics, and stake holder involvement. Observationally and experimentally assessed measures of habitat qualities, biodiversity, and ecosystem processes will provide information on present-day ecosystem and landscape properties.
Combinations of several retrospective vegeta tion history and archaeological methods will provide information on long-term natural changes, human settlement, timber logging, grazing pressure, economics, and human well-being. The project will thereby be able to analyse patterns in biodiversity and ec osystem processes in relation to human land-use and landscape history. The project will study forest landscapes along east-western gradients in South-and Central Norway, in particular forest landscapes close to Oslo, where strong and different interests a re in conflict as regards the value, management, and use of the forests. The modelling approach enables us to produce decision relevant information through more efficient incorporation of existing knowledge and new data collected in the project.
