Here Today, Gone Forever:
Plant Extinction Now and Conservation Strategies for Tomorrow

Two Tuesdays: November 17 & 24

11 a.m.– 12:30 p.m. EST | Online

Plants are essential to all human existence, yet the topic of plant extinction has received little comprehensive study and analysis until recently. In this two-day, online symposium, a group of international experts in biodiversity, conservation, and extinction will present the state of knowledge, trends, causes, and consequences of the plant extinction crisis. In addition, they will discuss strategies for preventing future precipitous declines in biodiversity. Each day, opportunities for asking questions and engaging in discussion with the experts will follow their presentations.
