In reply to gaz.marshall:
There are quite a few stakes on both sides but they can be hard to locate once the bracken is up. Once found I've always tried to put some slates around the base to try band make them easier to spot, I know they do go missing from time to time though.
Like tmawer said, many just belay from the tree on Kick Off or even ab down off a sling and belay the second from the floor, the second can then clip to the sling, double the rope and ab off, saving the tree from direct damage.
