Those trees were small and I'm confident they didn't meet the diameter for Parks to begin to care.
The two Locust on Gloucester? I'm used to trees where it takes two or three people to hug it. I don't know off hand what the city's minimum diameter is before they take control of the tree's future regardless if it's on public or private property. I'm assuming it's more than a foot.
