This presentation will cover common tree disease and insect problems in the Portland area, and the impact of changing climate on those issues. Climate models predict that the PNW will continue to see longer, warmer, and dryer summers with the possibility of increased winter storm severity. The impacts of these environmental changes on disease and insect concerns for landscape trees will be discussed, with a focus on what types of pest and disease pressures are likely to increase, and possible mitigation strategies.
