AB Fusarium circinatum is the causal agent of pine pitch canker disease (PPC), affecting Pinusspecies and other conifers (i.e., Pseudotsuga menziesii (Mirb.) Franco.), forming resinous cankers onthe main stem and branches and causing dieback in the terminal guide. This pathogen is spreadingworldwide, causing economic losses by converting plantations into standing timber without anypotential for future production. The disease was recently detected in Northern Spain in plantationsof Pinus radiata and forest nurseries. The aim of the work reported here was to study the roleof climatic and topographic variables, soil properties, and stand characteristics on PPC. For thispurpose, we surveyed 50 pine stands in Cantabria and quantified the percentage of trees showingthree symptoms in each stand: canker, defoliation, and dieback. We investigated the predictivepower of 30 variables using generalized linear models and hierarchical partitioning. Both approachesyielded similar results. We found that the three symptoms correlated with different explanatoryvariables. In addition, more trees exhibited cankers in the proximity of the coast and the BasqueCountry. Additionally, our results showed that low canopy cover is related to a high level of thedieback symptom. Overall, this study highlights the important variables affecting the distribution ofPPC in Cantabria.
