Read an interview with Division 7 Coordinator Eckehard Brockerhoff of Scion (New Zealand Forest Research Institute) about the work in IUFRO Division 7 and the All-Division Meeting at the IUFRO 125th Anniversary Congress. Division 7 deals with topics that are all concerned with forest and tree health, and the causes of interactions between air pollution and climate change, tree pathogens, and tree-feeding insects. Dr Brockerhoff pointed out that biological invasions and invasive species have been occupying much of this Division's time. The impacts of invasions are so pervasive and fundamental, and there are no simple solutions. They are an unwanted consequence of international trade and the movement of people from country to country. "At this Congress we've learned, among other things, about the progress in our understanding of what makes these invasive species so aggressive and how we can better predict the types of species that behave in this way," Dr Brockerhoff said.
