As global trade has expanded, there has also been an accompanying increase in invasions of insects and pathogens into areas where they never before existed.

Meanwhile, climate change is affecting the geographic distribution of host trees and their associated insects and pathogens. Increased pest impacts – both native and alien – can be expected.
