Both are common buckthorn? For the 1st one... it just looks like it(and those white stripes though) and the 2nd one I've seen a picture very similar to that..

Yep, your turn.

Try to answer the following (easy questions) without a binder! 
1. About what percent of introduced species became invasive species?
2. About how much economic damage(not including prevention) do invasive species inflict each year?
3. Name three important Invasive species councils/companies.
4. What does the Lacey Act do to help prevent the spread of Invasive Species. 
I made these questions without a binder, and you should be able to answer these without a binder as well!  :D

1. 1%
2. 178 billion?
3. USDA, California-IPC, and great lakes commission 
4. Is that the one that bans the transport of certain aquatic species?

[superpenguin666]

Yes, all of those are correct (except 2, everybody has sketchy numbers so I'm not even sure if mine is correct). Your turn!

1. Scientific and common names
2. What kind of environment does it invade?
3. Which native species does it typically replace?
4. Where is it native to?
5. What is it used for?

About the cost of invasive species annually, what I found is that most sources say 120-123 billion based on a 2005 Cornell study, but I found a few others:
Cornell university 1995: 138 billion dollars
Congress office of technology assessment said 1906-1991: 97 billion (total over the entire period from 79 species)
Cornell university 2000: 138 billion dollars

Also, the invasive species powerpoint on the soinc.org website says 137 billion
