Slash reduction inthe interior of BC is usually regulated / mandated by gov't for fuel reduction / wildfire abatement and forest health reasons. Silvilculture and reforestation also play into how much slash is reduced. All of our conventional ground based systems (skidder) are site prepped after harvest - mostly machine piled and then burned in the fall. Higher elevation zones may have different site prep prescriptions due to cold and / or wet soils - mounding.
The cable and heli blocks usually have more slash as it is not physcially possible to machine site prep these areas.
As for utilization .... we suck at that. Round here only the best goes on the truck and I have burnt some massive slash / debris piles. I'll post some pics later.
As for your delimber .... we call them strokers or jammers around here. Not many used as most contractors use the Waratah processor heads on track mounted hydraulic log loaders of excavators (shovels?).
Stokers are best suited for road side harvesting (no landings) where the skidder brings the drags to within 2 tree lengths of the road and the stoker processes the logs to the road side. That way all of your slash is set back from the road edge and all of your logs are processed and decked at the roadside. Roadside works best where all the timber is the same (Lodgepole) or where all of the timber is bing processed to one sort (sawlog/pulp, etc.) We can have up to 7 species and and 2-4 sorts per species so we rely on landings more and the Waratah processors. We sort and process everything in the bush and then straight to the mill (bush run).
Some contractors are running special feller / processor heads so that can fall a bunch of wood and then limb and process to length at the stump. The the wood is forwarded to road side. Your slash is then left in the block and again gets piled and burned later.
