There's a new National Geographic special about invasive species coming up on PBS this Earth Day (April 20th). The series, titled "Strange Days on Planet Earth," is hosted by Edward Norton (what, Alan Alda wasn't available?). The "Invaders" episode will be the premiere, and it looks like they are going to cover a variety of ecosystems, from oceans to islands to the mainland. The companion website features links to mapping tools, expert opinions and a very cool interactive search for invaders in a virtual house.
Thanks to a member of the NEANS Panel for posting about the show.
