Keynote speaker: Doug Tallamy, PhD
Tallamy is the T. A. Baker Professor of Agriculture in the Department of Entomology and Wildlife Ecology at the University of Delaware. His presentation, “Nature’s Best Hope,” will detail how choosing the right plants for our landscapes can address the biodiversity crisis and help fight our climate crisis as well. Learn simple steps each of us can take to reverse declining biodiversity, and why we must change our adversarial relationship with nature to a collaborative one.
