For those interested in Invasive Species!

I received a link to this site: http://www.invasive.org/ from someone who thought I could get plants from them (Baystar vine, Schisandra glabra) . this struck me odd since Baystar vine is neither exotic nor invasive, and is actually considered endangered in several of the states where it is native.

Anyway, I had a look around and it seems to be a decent site (though it looks to be predominantly geared toward the south)

Thought I'd pass it along, Happy Holidays to all!

They have beyond the basics and it is a very good site. Glad you posted a link as that is one of my favorite websites.

Here's their link to our side of the Rockies-
