Connie Barlow introduces in January 2014 a learning and action series for helping trees adapt to climate change — species by species, decade by decade. Citizen naturalists are invited to research a favorite native tree species and begin to work with others to keep up with the northward movement of forest zones by planting and monitoring small numbers of wild seeds of common species onto private forested lands well north of where those seeds were collected. This "assisted migration" in a time of unprecedented climate shift will be increasingly necessary in the decades ahead. Foresters can create the maps to show us where species will need to move to. But we citizen naturalists will play a complementary role in ensuring that the full diversity of genotypes keeps pace with a warming and drying continent. NOTE: This podcast is the soundtrack of a richly illustrated videoblog by Connie that is posted on youtube: VIDEO: Climate, Trees, and Legacy.
