stump heights
quote by clearance:
Out in the bush I never see low stumps, where are you talking about? I like to cut where its good, waist high, might cut it low after. Snags are always to be cut high, safer that way.
Clearance, low stump hieght should be found on any crown land in BC that has been logged. I have seen blocks re cleared when the snow melts. Other then the loss of mechantable timber, beating up on skidders, the forest service can fine for leaving high stump hieghts; I have not heard of anyone getting fined mind you.
One advantage of cutting low with smaller timber is you can push with your shoulder. Pushing as you place the back cut will push the timber over against the lean; the lower the stump shot the more leverage generated. Some fallers employ pushers with 10' sticks to push smaller timber into lay to save on shoulder muscling and or wedging.
When it comes to snags you are right, it is generally safer to cut snags high to avoid unsound wood close to the ground. Well there is no formula to presscribe to every snag, I have found with snags that are small enouph to be pushed over against the lean [by my self] that cutting lower to generate more pushing leverage is safer then cutting higher and wedging. I personelly have had far, far more tops and widow makers etc break up and come into my position from wedging then dead trees losing there hing wood from cutting lower. Generally speaking, when it is avialable, cutting up with a safety wedge placed and knocking a snag over with another large live tree is safer then wedging it over. Obviously residential work does not lend itself to these scenerios well.
