at least some that hasn't had the ravages of white ants. I had many metre + long sections (about 6 to 700mm dia) that were stored poorly on the ground. Kept to mount very large mature staghorns (supurbum sp) like the small one in the picClick image for larger version.

Anyway time to mount them (a 2 man job) came, and all that was left of my log sections were the "iron bark" exteriors: white ants ate out the whole interior of almost all the large logsections.

The one in the pic is mounted on a ext ply base with appropriate filling as trees such as the Leopard tree Caelaspinia sp.( now Libidibia ferrea) does not have suitable bark for the fern.
