The fact that is killing native vegetation that has more of a beneficial impact
to the wildlife of the United States.... In fact as a whole loosetrife has a
very small amount of wildlife that is attracted to it. It may be pretty but it
isn't something anyone should want in their yard as it is extremely aggressive
with no native enemies to keep it in check. It's bad stuff.
