The Marion Natural History Museum would like to thank David Orwig, forest ecologist with the Harvard Forest, for his wonderful presentation about Old Growth Forests on April 7. Orwig discussed some the tree species to look for and explained that the size of the tree does not matter when looking for truly old trees. He showed us how to determine the age of a tree, why the same species of tree might have different bark depending on age and why some of the oldest trees can be relatively small in size. A Vimeo
