Maynard's largest trees (prove me wrong)

The "Buttonball" sycamore in
Sunderland, MA

This will be a work in progress, especially as more tree species are identified and competing trees are nominated for what is already on the list! 

Determining how large a tree is actually has a formal definition involving girth, i.e., circumference in inches at 4.5 feet off the ground, plus height in feet plus 0.25 times average spread measured in feet, 'average' coming from adding widest spread and smallest spread and dividing that by two. The end result is a point score referred to as "Tree Points." Massachusetts actually maintains a big tree registry, for which it is possible to nominate trees and a field inspector will visit the site to verify measurements. See https://www.mass.gov/guides/massachusetts-legacy-tree-program#-is-your-legacy-tree-a-champion-tree?- I suppose barring any expectation that a Maynard tree is the state's largest, I can purchase a clinometer and a measuring tape, and start stalking trees on other peoples property. However, for the moment, for the trees listed here, the listing is based on my unmeasured eyeballing: 

Golden Chain Tree

Paper Birch: back yard of 10 Maple Street

Eastern Redbud: side yard of 10 Maple Street

Golden Chain Tree: back yard of 10 Maple Street

Sugar Maple: back yard of 12 Maple Street

American Dogwood: front yard of 12 Maple Street

European Copper Beech: side yard of 80 Acton Street

American Sycamore: corner of Nason and Main streets

These are by no means the largest in the state. For example, the beech tree on Acton Street has a diameter of 6.7 feet and the state's largest is reported at 8.4 feet. The "Buttonball" sycamore, Sunderland, MA, has a diameter of 8.1 feet and height >110 feet. Its age is estimated at ~400 years.
