🍁🍂 Did you know that PEM’s copper beech tree and black walnut trees are some of the biggest in the state?
Our staff recently measured both trees to see if they qualify for the Massachusetts Legacy Tree Program, a program where the Department of Conservation and Recreation Forestry Program recognizes the largest and significant trees within the state. The results are in, and the copper beech (picture above) is now registered as the 15th largest of its kind in Massachusetts, and the black walnut is the second largest!
