Tree cages?

[jbsegal]

... trying to distract myself...

Do you recognize these things?


They seem to be one form of a tree pit cage.

Cambridge has particularly nice (narrower - about 3' diameter) ones around Porter Sq.

What else might they be called?

Where might I get one?

ETA: http://www.urbanaccessories.com/ has some NICE stuff.

Those things are to protect the trees from dogs At least thats what I thought they were for. I have no idea what to call them. Tree protectors maybe? If you go to google images and search on tree protectors you get a few pictures of them.
