Lynda Mapes’s book—Witness Tree: Seasons of Change with a Century-Old Oak—is now out in paperback, from @UWAPress. Lynda is out and about in the Northwest reading from the book and answering questions about how she used a single red oak to tell a complete story about climate change. Check your local bookstores and university calendars for Witness Tree events. @LyndaVMapes image: Katja Schulz CC BY 2.0
