At home in the Pacific Northwest woods
After many years of service, wildlife biologist Betsy L. Howell (’87 Wildlife Mgmt.) wrote about her calling in Wild Forest Home: Stories of Conservation in the Pacific Northwest (The University of Utah Press, 2024).

Howell talks with Washington State Magazine about her career, conservation, and time at Washington State University.

A stormwater priority: Protecting coho salmon from tire chemicals
Coho salmon in urban areas were dying from stormwater runoff, but scientists didn’t know why until a few years ago.
A team of researchers from Washington State University and University of Washington identified a chemical found in tires as the culprit.
Tires contain 6PPD, which keeps the rubber from cracking after exposure to ozone in the atmosphere. But 6PPD also reacts with ozone, forming the organic chemical 6PPD-quinone.
During rainstorms, tire dust washes into rivers and streams, where 6PPD-quinone is lethal to juvenile and adult coho in small doses. It’s a complex issue—with no easy fix.

Exploring weather extremes
Scorching heat and record cold. Prolonged droughts and flooding from heavy precipitation. Lightning storms that ignite wildfires.
At the Climate Extremes Laboratory at Washington State University Vancouver, Deepti Singh and her students are working to deepen the understanding of extreme weather events—both in the Pacific Northwest and around the world.
“As the climate warms, the probability of experiencing these record-breaking weather events increases,” says Singh, assistant professor in the School of the Environment. “They affect our food security, air quality, water supplies, and energy production. And weather-related disasters influence human migration patterns.”
