Yah, they're helping us transition to the plantation resource of the future. They haven't planted the trees yet up here but.... yanno they're the government it doesn't have to make sense. The big one in my block is pipe. a 25cm diameter log can carry a 4 cm pipe and be compulsory. A 40 cm diameter can carry 19cm of pipe. A 50cm diameter can carry 28cm of pipe. A 60 can carry 34.... and by the time you get up to a 90 you can stuff a small child up the hole to look around with a flashlight. In these species the wood outside the pipe is perfectly fine.... pipe in no way affects the strength or durability of the surrounding wood. But it's pretty hard to get recovery when half the log is just a gaping hole. The upside of learning to run a mill for profit cutting trash is that when I get good logs like my privately sourced ones I am just plain lethal... bad logs will surely teach you how to run a saw if you don't go broke first.

Ahh ok, I get you now, that certainly changes the game. Here the size of the rot/pipe in relation to the diameter can pretty quickly turn it to grade 4 especially on smaller wood. Lots(butt ends) gets trimmed off in the bush if rot is showing. The larger western red cedar can be bad for hollow and heart rot and if it grade 4's in the bush it can be left or sometimes a post and rail fellow would buy it.
