You have a very good point, especially in areas in which the species is 
not already common. Here in the Finger Lakes it's already a very common 
tree. Locust stakes were commonly used for fenceposts in vineyards, 
especially before the introduction of treated wood and metal posts. I 
don't know whether locust was already in the area, was planted for use 
as fenceposts, or whether green wood was used for posts and some of them 
sprouted. I haven't seen it invading the woodlots here -- has anyone 
else in this area? maybe I've just missed it -- but it will certainly 
invade open ground and brush lots, as well as establishing as a weed in 
vineyards. I did warn in my posting that it's invasive, but probably 
should have stressed this more.
