An extensive network of professional, academic, and amateur botanists are actively engaged in the conservation, management, and study of Washington’s diverse flora.  Their expertise ranges from how best to manage biodiversity, to understanding climate change impacts on plant communities, to naming and classifying the flora’s rare, common, and invasive elements.  Invited speakers and poster presentations will share new insights and discoveries about these topics and more.  Participants from throughout Washington and adjacent areas will have the opportunity to exchange ideas with colleagues within and across disciplines.
