Want info on invasive species?

I found a website, titled the Global Invasive Species Database that lists all the invasive species throughout the world. You can be specific by typing the country, location, species name, habitat and/or organism type. I found the Nova Scotia coastland has 5-7 invasive species ranging from algae, herbs and molluscs. Interestingly, it also lists the native species of NS that are invasive to other countries. It also lists the 100 worst!
