Fellsmere Pond MA, USA
This tree is growing on the fellsway side of the pond, near the benches.
This is a state listed invasive, prohibited, species named ailanthus or tree of heaven or stink tree.
It is not sumac which is native(has value), has fuzzy stems and remains small.
Currently, there are two juniors, one on either side of the the tree pictured.
You can rub the leaves and take a whiff. That is an easy way to identify this tree (and no fuzzy stems).
If left another 5 years, this tree will be 30 feet taller (can reach 80 feet in 10 yrs). AND there will be another 30 or 40 juniors growing too.
It would be great if you can remove this tree and any juniors you see. There may be smaller ones I missed in the vegetation.
Miserable tree.
Thanks.
