Plant Science Conversations: Keeping Tabs on Trees

Ever wonder how many tree species are native to the U.S.? And what can be done to protect them? Join Dr. Murphy Westwood and Devin to learn how a team of scientists and public gardens recently created a new checklist of the 881 tree species native to the contiguous U.S. and conducted a first-of-its-kind analysis of threats and extinction risk at the species level. The conversation will highlight how this new, freely available resource can support prioritizing approaches to tree species conservation and forest restoration in a changing climate. 

This program is offered as part of the Garden’s week-long celebration of Earth Day. It is also offered as part of the Garden’s partnership with Morton Arboretum and NatureServe. 

Presenters: 

  • Dr. Murphy Westwood, Vice President of Science and Conservation at Morton Arboretum, and 
  • Devin Dotson, Senior Communications Specialist, U.S. Botanic Garden
