We check in on our year-long project #BLTrees, following the seasons through the trees around us with Marielle Anzelone, urban botanist and ecologist and the founder of NYC Wildflower Week. This month, Charles Nilon, professor in the University of Missouri School of Natural Resources, talks about his research and the intersection of trees and environmental justice.

⁦@BrianLehrer⁩ #BLTrees my oak is looking pretty majestic this month! Very fully leafed in. Who takes care of the trees on my street? No one! Some new ones were planted last year. I watered the one in front of my house. The rest died :/ pic.twitter.com/kLUAi85UiQ
