Sponsors and What Their Investments Mean

We talk about sponsors quite a bit when we plan conferences.

Their investments in the PNW-SETAC community and its work is impactful and meaningful on a personal basis. Their contributions help us to provide a financial lift for students- our future analysts– and help us support our community-based partners, including the critical role of tribes, and reduce costs for the nuts and bolts of operational costs that make holding a conference possible.

Their generosity is also notable in that they are markers of supporting science. We thank them and feel enormous gratitude.

2025 Theme

From Mountains to Sea

For the second time in its history, PNW SETAC will be holding its annual conference in the state of Idaho and we welcome you to join us in Boise on April 14-16th, 2025!

Our chapter is the largest SETAC North America chapter, with our membership spanning Washington, Oregon, Idaho, Alaska, and British Columbia. We are excited to grow and continue strengthening our ties with all our members, as well as emphasize inclusivity and collaboration across state borders.

The Pacific Northwest region spans a wide range of diverse and interconnected ecosystems. At our upcoming conference, we ask you to consider how your research and projects may align within or span  one of four ecological spaces from our regional biomes:

  • Mountains and Terrestrial Systems
  • Rivers and Freshwater Systems
  • Ocean and Estuarine Systems
  • Mountains to Sea – Cross-systems Thinking- From the Rockies to the Pacific Ocean

We often think of legacy and emerging contaminants—their behavior, effects, and fate—in one space but the fate and transport of these contaminants often stretch across habitats and borders. How are contaminants such as PFAS or 6-PPD behaving in a freshwater ecosystem compared to a marine environment? Ecological risk assessments and remediation activities conducted in a riverine system can be just as impactful further downstream, in river corridors and off-channel environments. What ecological or chemical data trends are emerging at upstream versus downstream sites within a watershed?

Mining activities have a historical importance in many parts of the Pacific  Northwest—  ecologically, culturally, and economically. In what ways are these sites being managed for restoration and/or reclamation to keep the industry sustainable while respecting Tribal needs, treaty obligations, and historical use patterns ?

Overarching themes we would like addressed are human health impacts, aspects of environmental justice, and science communication.

Please reach out with any questions to Michelle Knowlen.
