Urban sprawl and development can lead to a reduction in the canopy volume of urban trees, which reduces the benefits provided by those trees. When selecting tree species for urban areas, carefully considering the site criteria can lead to greater benefits and longer-lived trees. Selecting a diverse array of trees contributes to urban forest diversity which can help avoid catastrophic tree losses due to pests and climate change.  Read More "A Tree Selection Survey of Tree City USA Designated Cities in the Pacific Northwest"

How Do Urban Tree Managers in the Pacific Northwest Decide What Trees to Select?

Dr. Paul Ries, Oregon State University, Corvallis, OR & Joshua Petter, Tree Solutions Inc, Seattle, WA

Tree selection decisions at the municipal level are made by many different natural resource professionals, including arborists, urban foresters, planners, and landscape architects. A recent study by Oregon State University aimed to explore how managers make tradeoffs and prioritize different tree selection criteria to better understand how trees are selected for public lands. We surveyed primary contacts for Tree City USA designated cities across Oregon and Washington. Of these municipalities, 79 out of 151 responded (52.3% response rate), with six municipalities providing responses from more than one department for a total of 85 responses.   Read More "How Do Urban Tree Managers in the Pacific Northwest Decide What Trees to Select?"

I arrived at the University of British Columbia just over a year ago to serve as Program Director for UBC’s urban forestry program. Although I still have some projects underway at my previous institution (Virginia Tech), I am looking forward to working with partners in the PNW to continue my research program in belowground systems (soils and roots!) in urban forests.

Research on the relationships of nature experiences in cities and human health has been underway for decades. In recent years the number of studies has surged, providing important insights. Nearby nature is not just nice to have, it is profoundly important for the wellness of people and their communities. Read More "Trees for Human Health & Wellness"

There is increasing interest in understanding the governance of urban forests, that is, the ways in which we make strategic decisions about our cities’ trees and woodlands. Urban forest governance is often complex, involving a wide range of so-called ‘actors’. Obviously municipal urban foresters or other green space professionals have an important role to play, but many other individuals and organizations are involved as well.
