Hi Matt:
I just noticed that the Maine DEP, Bureau of Land and Water Quality
has online a publication "
The Buffer Handbook Plant List
", last revised in 2001. This list includes European alder (Alnus
glutinosa) as something explicitly recommended to plant in buffer
zones. From Alice's comment about establishment in watersheds in
VT and NH, we'd certainly be safe in recommending to the DEP that
this should be taken off the list.
Thanks for bringing this up.
