A risk to the forestry industry? Invasive pines as hosts of foliar fungi and potential pathogens

Pathogen accumulation on an invasive plant species can occur over time, through co-invasion, or adaptation of native pathogen species. While accumulated pathogens reduce the success and spread species, they also spill-over into communities valuable non-native populations. Transmission may be density-dependent, with dense populations creating better opportunities for than scattered individuals.
