Speakers Announced For Oregon’s Largest Urban Forestry Conference (Photo) - 03/30/26
EUGENE, Ore. - The many ways trees protect human health is the focus of the 2026 Oregon Urban and Community Forestry Conference to be held June 4 in Eugene at Venue 252. The full lineup of speakers – 11 in all – has now been announced. Conference theme is We Thrive When Trees Thrive.
This year’s keynote speaker is Geoffrey Donovan, a natural resource economist with the private consultancy firm Ash and Elm Consulting, LLC. When he was a researcher based at the USDA Forest Service’s Pacific Northwest Research Station, Donovan published a ground-breaking study that found each tree planted in Portland by the non-profit Friends of Trees was associated with significant reductions in non-accidental and cardiovascular human deaths. Donovan had access to years’ worth of tree planting data from Friends of Trees. Specifically, he used the planting data from the nearly 50,000 trees that organization had planted in Portland neighborhoods since 1990. Donovan was able to rule out other possible explanations for the lower death rate like race, education, and income, by using the statistical models from the American Community Survey. The findings were published in December 2022 in the journal Environmental International.
Donovan’s work has also shown a strong correlation between sudden tree canopy loss and higher death rates using data from the Midwest where ash trees were suddenly killed by emerald ash borer, leaving residents exposed to air pollution, noise, and other stressors. He has also investigated how pregnant women in Portland who live near large shade trees are less likely to give birth prematurely.
Other presenters include:
- Jared Hanley, NatureQuant, speaking about how to measure the economic contribution of trees to public health
- Leah Fisher, Clackamas Co. Public Health, and Jairaj Singh, Oregon Dept. of Transportation, discussing cross-sector efforts to expand tree canopy using health data
- Gwynne Mhuireach, University of Oregon, exploring the hidden links between forest bathing and human health
- Alby Thoumsin, Sperry Tree Care, how to honor and care for older trees
- Sarah Gaskin, A Plus Tree, LLC, sharing lessons learned from novel wood waste solutions
- Drue Epping, American Forests, on positioning trees as integral solutions to community challenges
- A three-person panel of Mari Aviles, Kat Bethea and Jennifer Killian traces the lifecycle of urban trees from species selection through establishment with lessons for how to achieve long-term success
