it seems to me that the reversion of this page didn't actually restore all the legitimate text that was there a few months ago. Someone look into this. 220.127.116.11 23:52, 1 February 2007 (UTC)
Yes, someone please bring back the old text!

North American invasiveness 
According to NatureServe, Acer platanoides is an invasive species in North America.
- "Acer platanoides, a commonly planted shade and street tree has been escaping and increasing its presence in natural areas for several years. Reproducing vigourously by seed, and resprouting after cutting makes it difficult to eliminate any escaped plants. Many states have since banned the use of A. platanoides as a street tree, although the species has already become widespread."
I think this article could use a section on its non-native range and invasiveness. FUNgus guy 12:50, 8 May 2007 (UTC)
These statements are contradictory. One from the Norway maple topic and one from the Sugar maple topic. Personally I think neither is helpful in id.
" ... the leaf lobes of Norway Maple tend to have a more triangular shape, in contrast to the more squarish lobes often seen on Sugar Maples"

Not widely accepted 
I think it's dangerous to categorize Norway Maples as invasive in the same sense as purple Loosestrife or horse tail weed. While some states have listed Acer Platanoide on their invasive lists, it is not widely accepted throughout the entire country. I have never seen Crimson King Maples taking over a field like loosestrife or other invasives that are truely a problem plant. 18.104.22.168 13:37, 17 July 2007 (UTC)
- Well, I've added a reference which puts it in exactly the same category as purple loosestrife (in one region; these things often vary geographically due to climate, etc). That reference is just a start, though, and there may be better ones. It doesn't go into much detail about where it is found, how big the stands get, etc. As for Crimson King and the other cultivars, populations will generally quickly revert to type (via mutation or interbreeding) as soon as they escape cultivation, as most of them are less fit than the wild type (in the sense of competing with other trees, each other, etc).

Native's vs Non-Native 
Like I said it's not widely accepted and the fact that the link includes it in the same category as purple loosestrife just reinforces my point. Also, looking at the link and Sweetgum is listed as a replacement which is marginal in midwestern states. Maybe wiki should have a section about non-natives and native species and the truth involving each instead of just black balling something because it's not originally from this continent; I don't see anyone trying to get rid of dogs and I see a lot more of them than any norway maple reproducing, actually I'm still looking for a norway maple growing in the wild... 22.214.171.124 (talk) 04:35, 5 February 2008 (UTC)concerned user
