Question
Does anyone keep a record of Pine trees recorded in Maine. How can I get information on the circumference of the largest trees on record for size?
Thanks  

Answer
Each state does annual measurements of the number , species and size of the trees in that state. You can contact the Maine Forest Service and they can give you the data you need. Here is the web link to their contact page.
