Scientist
Geoffrey Donovan is a research
forester with the station’s Goods, Services, and
Values Program. His research explores the economics of
wildfire management and, more recently, quantifies the
benefits of urban trees. His urban forestry work has
revealed sometimes surprising associations between urban
trees and a range of services, from increasing
home sale prices and reducing
summertime energy use, to reducing
crime and promoting
healthier babies. His latest research suggests
that increased
rental prices and better community health also may
be associated with the presence of urban trees. Learn

i-Tree
Eco is a software application that combines field
data with local hourly air pollution and meteorological
data to quantify urban forest structure, environmental
effects, and value to communities. Recently, the tool
was used to conduct a station-funded multi-year study
of Seattle’s urban forest that revealed, among
other things, that the city’s trees are worth $4.9
billion.
