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.
