Hello everyone. My name is George Fieo and this is my first post. I reside in Limerick Twp., SE Pennsylvania. Today my son and I rode our bikes along the Schuylkill River searching for some trees to measure. We measured several trees and the last was one I could not identify. I think it may be a Hazel alder. Most of the other trees leaves have fallen or are in their final color stage. This tree is still green and is why I noticed it. It is a single stem that measures 27" cbh, 40' h, and 15' s. I will attach some pictures if anyone can help ID this tree. Here are the circumferences for the other trees we measured.

Tulip poplar cbh 213"

Silver maple cbh 244"

Red maple cbh 162"

Norway maple cbh 140"

Boxelder cbh 116"

Thanks, George.

Looks like European alder, Alnus glutinosa, frequently naturalized in the NE and Midwest.

George: I agree with Steve- A. glutinosa, European Alder, is also
know as Black Alder. Your picture made it easy to identify. Have you
used the USDA website plants. Here is the link for European Alder.
I was interested in your find because I came across on several weeks
ago and was stumped for an ID for several days. Mine was a single
planting in front of a school. I understand it has been used for strip
mine reclamation in the distant past. Probably for its nitrogen fixing
Were all your trees measured single stem? Have you compared them to Pa
Big Tree List?

Steve and TS, thanks for the help. The Silver maple is a multi stem and
its cbh was even larger but lost one of its main stems not to long ago. All
of the other trees are singles. I did get some pictures before my batteries
died. The Tulip poplar is hollow in the backside and large enough to walk
inside. I have met Scott and visit his website almost daily. I'm addicted!
I'll attach the pics for the Tulip poplar, Silver, and Red maples.
Later, George.
