2026 Plant Conservation Symposium
December 10, 2026 • LaSells Stewart Center, Corvallis
Registration Cost: $50
Held concurrently with the Oregon Interagency Noxious Weed Symposium
Restoring the Balance
Native Plants and Noxious Weeds in a Changing Landscape
The 2026 theme, Restoring the Balance, reflects a core truth: invasive plant management and native plant conservation are not separate endeavors but two halves of the same restoration imperative. We invite presentations that reflect this integrated vision—whether from the native plant side, the weed management side, or the growing middle ground where the two disciplines meet.
Registration will open at 8am, sessions will begin at 9am.
Registration covers coffee, tea, and snacks in the morning and afternoon, plus catered lunch (meat and vegetarian options).
A detailed agenda and abstracts will be available soon.

2025 Theme: Plant Conservation in an Era of Rapid Change
Virtual | December 9th, 2025
The challenges facing plant biodiversity have never been more urgent—or the solutions more complex. From navigating climate uncertainty to securing sustainable funding, plant conservation requires innovative thinking, interdisciplinary collaboration, and adaptive strategies. This year's free and virtual symposium will explore how conservation professionals are addressing these challenges while developing resilient strategies for protecting Oregon's state-listed and regionally rare plant species.
