Dr Paul Barber of ArborCarbon fell in love with trees and ecology as a young man and brings that passion and knowledge to his talk with Deryn and Steve.  He covers tree technology, the environmental impacts of healthy trees, and the emotional connection people have to their trees. If you're trying to choose a good tree for that tricky spot in your yard, or just love the spectacle of a well placed Oak or Ash, he's got something for you.
