Gravestones for "invasive" trees

Jeremy Mora writes in with an interesting story. In LA (as here in Minneapolis), the condo boom continues unabated. Part of the condoization of the neighborhood involves fixing sidewalks that've heaved up from the expanding of roots by ancient trees. Apparently they're cutting down these "invasive trees" and marking the carnage like this: Jeremy says ten trees were leveled and marked like this on Alameda in downtown Los Angeles.

Also: Jeremy points out a friend's blogworthy site, Treestories.
