Steve,
Prunus avium? Will F. Blozan President, Eastern Native Tree Society President, Appalachian Arborists, Inc. _____ From: [email protected] [mailto:[email protected]] On Behalf Of Steve Galehouse Sent: Friday, April 03, 2009 4:35 PM To: [email protected] Subject: [ENTS] Re: Tree ID Help Jenny- The new photos are not river birch; probably cherry birch as you suggest, but could also be of European alder. I've attached a photo of cherry birch taken locally, and will go get a photo of river birch for you to compare.

Wouldn't you be able to see a trace of the horizontal lenticels? Also, the tree may not be growing straight because of soil erosion. It's on a bit of an incline - which I didn't show very well since I didn't get the base of the trunk. I added 3 pictures of the guy next door which I think is a big (to my inexperienced eyes!) Betula lenta. Can you tell from the photo? It could certainly be a river birch, though. http://picasaweb.google.com/JennifDudley/TreeIDHelp?feat=directlink Jenny On Apr 3, 3:44 pm, Steve Galehouse <[email protected]> wrote: > Jenny- > > After looking at your other photos more carefully--not focusing on the > bark--I think the tree in your photo is a river birch, Betula nigra.
