The Challenge of Invasive Tree Pests Can we be better prepared for the next outbreak?

摘要

Managing invasive insects and diseases is of great importance to everyone in the plant health care field, and to communities as well. While native tree species have co-evolved with native tree pests, reaching equilibrium over time, new pests and climate change have altered the norm. Native species are dying from pests that don't belong here or whose damaging impact has been enhanced by the changing climate.The National Invasive Species Council (NISC) defines invasive species as, "An alien species whose introduction is likely to cause economic or environmental harm, or harm to human health," adding that it is a species that is, "Non-native to the ecosystemunder consideration." The emphasis is placed on risk of environmental harm, native species dislocation, or potential harm to humans or other native species. We must be better prepared with systems and processes to address invasive species and with our response when they arrive.
