Easily‐measured site variables (e. g. absolute elevation, exposure, slope and aspect) were used to prepare different regression models to predict the extent and severity of attack by C. sororia on a number of different provenances of lodgepole pine. Using a simple climatic‐zone division of Scotland, a significant relationship between percentage infection on whorls 1–5, 6–10 and 11–15 and elevation, exposure and site aspect was demonstrated, whereas severity of infection was not well related with these variables in any of the models tested. This suggests that severity of infection may be influenced by other independent variables, e. g. persistence of liquid water on bark, success of spore germination and host resistance. This approach offers an opportuity to predict the possible susceptibility of different provenances of lodgepole pine under specific site conditions.
