Just copied this off of another group I belong to, credit to Brian J. Torreano. Most of the list does not pertain to us but more info is better than no info.

What I found interesting is the geographic bounderies for some of the banned plants ......... Huh? You mean I can grow them on this side of the fence but not on the other??:hihi:

I suppose it could have been a lot worse. This shouldn't affect hobbyists too much. I think the DNR was working on this for a while. They have a list of banned fish too that isn't too bad, but has a number of species listings that I don't really understand.

I think that those within-state boundaries might be to keep stuff out of areas where it isn't so well-established. The huneysuckle Lonicera maackii, for example, is pretty thick here in the southern part of the state, but there is less of it Up North.
