Japanese hops
Originally uploaded by urtica

I remember passing by this plant in Boston this past spring and just stopping and staring. The vine had pretty much taken over the raised bed it was in, except for the tree in the center. First time I have ever seen the invasive Japanese hops (Humulus japonicus), live and in person, and it was in the middle of one of the most pavement-locked parts of the city. Not sure how it got there, but the bed was cleared a few weeks later and the hops didn't come back (it's an annual plant).

Spotted Turtle-dove
Originally uploaded by aaardvaark

Nice shot of a spotted turtle dove (Streptopelia chinensis) in a park in Australia. As its scientific name indicates, this species is native to China, but it has been introduced all over the world, from California to New Zealand, Australia and Indonesia.

Cirque du Pileum Rouge
Originally uploaded by Dixie Native

Last week on Flickr I happened upon a nice shot of an American robin dining on the fruits of the invasive Chinese tallow tree (Sapium sebiferum, also known as "popcorn tree"). A quick note to the photographer led me to a whole set of his shots of this tree, including several amazing ones of birds, such as the Pileated woodpecker shown here. Be sure to scroll down this page to view the photos and read more about Chinese tallow.

Thanks to Dixie Native for giving me permission to display this photo and for pointing me to his other shots.

This is the Golden Dewdrop plant, Duranta erecta, a shrub native to Tropical America but not to Hawaii, where this photo was taken. The photographer, Donna62, smartly noted when posting this lovely photo to Flickr that the species is considered one of Hawaii's Most Invasive Horticultural Plants, and this risk assessment will tell you a little more about why.

As with many tropical species, this plant is ridiculously showy, both in flower and fruit. Our invasives here in New England really cannot compete :-).

Heavily earthworm-infested soil
Originally uploaded by esagor
There's no "Before" shot here so you are just going to have to imagine that this patch of earth in Minnesota was once covered by a thick layer of leaf litter. You're not supposed to be able to see the exposed soil, it means that non-native earthworms have passed through and done a right job on the place.

Euonymus gone astray
Originally uploaded by urtica
Euonymus gone astray - this is a photo collage of an introduced Euonymus, naturalized in Canton, Massachusetts. I was lucky enough to get a tour of the site a couple of weeks ago.

The jury is not yet in on whether this is E. planipes or E. sachalinensis. The fruits were odd in that the number of locules (chambers) they contained varied, even on the same plant, between four and five.

Mongoose

The mongoose (Herpestes javanicus) was intentionally introduced to the Hawaiian Islands back in the mid 1800s as a biological control for rats, a job it failed at miserably.
