Not true for palms, they have 100% as vascular system, you can ring bark a palm but it wont die ..... ever! Might rot and fall over though.

Jim1NZ told me of this particular living pine that got riddled with spike wounds, and it declined. I'd say it's the same one. Of course it's a negative thing ... even in palms.
