On This Green Earth, Mary Mason, a Forest Geneticist with the US Forest Service, comes on the show.
Mason discusses the issues that are facing the North American ash trees. The ash borer invasion that slipped into the US around the turn of the millennium, most likely on a container ship, is now in 35 states and responsible for the deaths of hundreds of millions of trees.
