EFISCEN is a large-scale forest model that projects forest resource development on regional to European scale, based on detailed national forest inventory data and scenarios. These scenarios are mainly determined by management actions, but the model can also take into account changes in forest area, as well as changes in growth e.g. due to climate change. EFISCEN provides data on basic forests (species, area, stemwood volume, increment, mortality, age-structure), as well as ecosystem services (wood and biomass production, carbon sequestration, biodiversity, recreation, wind and fire risk), enabling the assessment of impacts of different policy and management strategies at the national and European level.
