The Consequence of Tree Pests and Diseases for Ecosystem Services


In the outlook summary of the paper, the authors summarize: Modern pest and disease management is based on an extensive science base that is rapidly developing, spurred in particular by modern molecular technologies. A research priority is to build a better understanding of why certain pathogens and insects become major pests and diseases. This will involve a better understanding of the molecular basis of pathogenicity and herbivory, as will ecological insights into why some species reach epidemic prevalence or abundance. It will also help anticipate which species may become a problem if they are transported to new geographical regions, recombine with other organisms, or experience new climatic conditions. However, identifying all species that may become pests will be impossible, and the Review stresses the importance of risk management at the "pathway of introduction" level, especially when modern trade practices provide potential new routes of entry. Last, when ecosystem services are provided by woods and forests rather than individual tree species, we need to understand better the consequences of pests and diseases that attack or feed on particular species.
