The LEDESS model was developed as a regional GIS model end of the 80's for landscape ecological evaluation of scenarios. The model has evolved into a broad integrated DSS focussed on interactive landscape planning and evaluation. Now the planning process with all types of landuse and socio-economic modules are involved.
Measures in the landscape or future land use is checked on abiotic suitability and valuable landscape patterns or socio-economical values. After choosing for the appropiate measures and future land use (targets) vegetation development in some time steps is calculated, based on the actual or changed abiotic conditions. Both vegetion structure and abiotic conditions (physiotopes) after time steps are input for calculation of habitats for 'keyspecies' (vertebrates). Some spatial conditions are used to calculate habitat patterns and size. In near future a meta population model will be linked to the habitat module.
The dss is based on expert knowledge. For some areas a specific version of the model is made 'LEDESS rivers'
