Rescuing my very large Cymbidium suave

[greengarden]

I have a very large Cymbidium suave that we rescued from under a bulldozer about 8 months ago when they were clearing my neighbour's suburban block. It's on a very rotten piece of eucalypt that was previously also infested with termites. Once my land has been revegetated a little more I'll pop it over the back, essentially returning it to the bush habitat from whence it came however in the mean time I need to try to solve the issue of it's fast deteriorating mount. The wood is literally falling apart and it isn't going to last much longer but I'm not sure what the best way is to rescue a plant of this size that is designed to live within as opposed to on timber? (It is atleast 1.5 metres wide with about 15 well established 'snakes', many new leads and atleast 19 new flower spikes forming at the moment!)

My current line of thinking is to leave it on as much of the current mount as possible and place the whole lot into a bed of coarse bark. However I worry about the potential for the wood to break down and rot the roots, or is this less of an issue given this species is adapted to living in rotten timber? Much of the outer wood has rotted leaving the roots quite exposed so I need to remedy this before the heat arrives...
