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