We have constructed a three dimensional model that gives us structural information about the Scots pine root systems in a forest stand and the spatial distribution of roots in that stand. The model allows us to make predictions how fast Heterobasidion annosum sensu stricto colonises the pine roots, transmits from one root system to another and to recreate the distribution patterns of the pathogen in time and space.
