Did you know that there is an interactive database of invasive species eradications on islands? The Database of Island Invasive Species Eradications has compiled information worldwide for islands that have eradication programs for invasive species. You can click on any of the marked islands and a details box will popup and show what the target species are, what stage the program is in (In progress, Successful, or Failed), and the last date of progress update. Many of the islands off of the U. S. coast have eradicated ungulates (sheep, goats, deer, etc.), rabbits, dogs, cats, and rodents. You can also search by a few different filters if you are interested in a certain species, place, or eradication status or method.
