Table 1 Relationships between the independent variables and marri canker incidence across the geographic range of marri (C. calophylla). Only non-correlated variables and cross-product terms with the highest significance are listed. Proportion non-native vegetation area in a 100-m radius around the survey sites. Model used: Logistic regression for proportion data, family = quasibinomial, following Crawley (2007)

From: Importance of climate, anthropogenic disturbance and pathogens (Quambalaria coyrecup and Phytophthora spp.) on marri (Corymbia calophylla) tree health in southwest Western Australia
