The system is called Peatland Management Decision Support System (PMDSS). Its aim is to support the implementation of sustainable land use strategies in Europe. The study is based on a multifunctional approach, where ecosystem functions are differentiated into production function, carrier function, regulation function, and informational function. PMDSS is implemented as an one-dimensional mathematical computer model in the spreadsheet program Excel. The spatial resolution is set to site scale. The model operates with annual time steps for a time span of 100 years. The amount of input parameters is reduced to parameters easily collectable within a few days and with low costs. The results give a rough estimate for the development trend of a peatland site. The applicability of PMDSS was tested in three case studies. PI Kiel ER
