The pathogenic fungus Heterobasidion annosum causes severe problems for forestry throughout the northern temperate zone, infecting mainly coniferous trees. Annual losses in the European Union are estimated at €790 million. The infection biology of the fungus is well described, although variation is considerable. This paper describes two modeling projects in Europe. The first, MOHIEF (Modeling of Heterobasidion infection in European forests), is a project within the European Union aiming to produce a decision-support tool for forest managers, as well as a tool for scientists throughout Europe. MOHIEF models infection and spread of the pathogen for various tree species over a range of forest conditions. The other project, Heureka, aims to produce a system for forest planning on strategic, tactical and operative levels in Sweden. Although national in scope, the model can be applied at regional and local levels. In Heureka the impact of H. annosum is one factor amongst other components that include growth and yield, wood properties, biodiversity, biomass-carbon relationships and forest-owner behavior. In this paper simulations of infection by Heterobasidion are demonstrated together with examples of how the models can be exploited, from a forest manager's and a scientist's perspective.
