Louisiana irises are a critical part of Louisiana natural heritage that have been greatly impacted by land use and climate change. During this symposium, iris experts, Patrick O’Connor and Charles Perilloux, will discuss iris species found in Louisiana, their discovery, natural history, and how iris distribution has changed over time – weaving in stories of human-plant interactions. They will also discuss the future of irises and what is needed for their conservation and adaptation. Expanding on her book, Using Plants for Stormwater Management, architect Dana Nunez Brown will focus on how irises and other species provide important ecosystem services and can be critical plants for stormwater management. After presentations from the speakers, an interactive panel discussion will be open to questions from attendees.
