Yeah, thought we still don't know if that was clumsiness (like running the lawn mower over it and trying to hide the evidence,) or malice (like deciding animals don't deserve memorials and destroying it for that reason).
Like with the Paulownia, we don't know exactly WHY they started slicing it up with a chainsaw. They took down both of the good Himalayan mountain ashes as well, but at least there they had the defense of maybe not seeing them as any different that the rest of the brush over there.
It sort of all boils down to the same point. I suspect that most of their clients are non gardeners who are content to turn everything related to the landscape over to them, so they are used to being able to do whatever they want with the areas and not having the house owners care.
Quite often, I don't take precautions to protect the stuff because I can't concieve of them doing anything to risk it since it isn't something they'd normally do. When they just randomly out of the blue decide to start weeding your flower beds (pulling up all of the flowers as well in the process) it is unexpected, since weeding isn't something that's a normal part of their job. That cost me my apple saplings back in college, and my chance to grow alyce clover seed to seed a bit later. And we had to put a little fence around the edge of the vinca to keep the Mazus in place (before it flowers, Mazus and one of the local weeds look pretty much the same.) Before I started using the cage, I had to remember to leave the outer three or four inches of the stump garden bare, or they'd kill everything with the mower and the edger (and, if I didn't put some sign of planting there, they'd literally run the mower over the whole thing, since they'd have preferred us let it become part of the lawn to make their lives easier. Ditto the vegetable garden, part of why we stopped using it is they would use it to turn the mower around on (without turning the mower off).
