Drought and Urban Trees

Urban trees are critically important to public health, habitability of urban areas, and mitigation of global warming. The water stress associated with recent record drought events has significantly reduced urban tree growth and their capacity to provide shading, cooling, and other benefits in metropolitan areas. Join us as we discuss short and long term drought affects on urban tree health. Learn the factors that affect water availability in urban trees, how these effects can be quantified, and how to use this knowledge to improve tree health care.

Susanna has her background in forest pathology and forest ecology, with expertise in genetics and genomics of tree resistance to fungal pathogens through her Ph.D. work at the University of Helsinki and her postdoctoral research at Oregon State University. At CAES, Susanna studies how physiological, chemical, and molecular tree stress signatures can be applied in tree health management. Current and upcoming research in the Keriö lab includes abiotic stress detection in urban maples, impacts of mycorrhizal inoculation on transplant shock in newly planted trees, and resistance of chestnuts to chestnut blight.
