My electronic field guide to "Invasive Plants in Winter" has finally gone beta, so to speak, over at the efgKeys website. It features invasives from the New England region, though those of you from other temperate parts of North America are sure to see some familiar species. To check it out, head over to the site and choose it from the pull-down menu in Step 1. The Java-based picture key is the coolest, but the software also serves up the key in several other flavors, like HTML and PDF. The best part about this is that all I have to do is set up a spreadsheet and some images, and the software, developed by the excellent EFG Research Group at UMass Boston, does all the hard work.
P.S. - The software is currently operating at port 8080...some firewalls automatically block this, so you might have to fiddle with your system to access the site.
