Calks – the loggers classic high-topped, steel-spiked boots which give steady footing while walking logs.

Carriage – Motorized or non-motorized unit that rides on the mainline which holds chokers and lifts logs off the ground.

Chaser – Person that unhooks logs on the landing.

Chokersetter – Person that wraps chokers (cables) around logs for machine (yarder) to pull to landing.

Clear Cut – harvesting method of cutting all trees down in a given area, which is biologically and economically sound and is generally practiced in Douglas Fir tree zones .

Conk – A fungus that grows on wood and is indicative of rot or disease in the tree.

Crummy – A loggers bus or crew vehicle.

DBH – abbreviation used by foresters which means a tree’s diameter at breast height-4.5′ above ground level.

Dog Hair – A thick growth of small, suppressed trees.

Faller – person who cuts trees down on the logging site.

Grapple – A heavy set of metal tongs, usually attached to the rear of tractors, which fasten around logs to bring them into a landing.

Hardwood – general term which refers to those species of trees that lose their leaves in winter.

Hooktender – The boss of the rigging crew – known as the “hooker” – generally runs a hi-lead logging show.

Landing – The place where the logs are dragged for loading.

Molly – A strand of wire rope that is weaved into a small circle. The loose end acts as a “cotter-pin” to hold pins in blocks.

One Board Foot (bd.ft.) = a board 1″ thick by 12″ square.

Pecker Poles – Small, skinny trees.

Rigging Crew – Loggers that set up and maintain cable yarding systems.

Rotation – the period of years needed to reproduce and grow to maturity a specific crop of trees. In Washington on the west side of the mountains, the rotations can begin as low as 40 years of age and go to over a 100 years for fine sawtimber. The eastside rotations generally start at about 80 years because of slower growth with drier conditions.

Road Change – Moving to an area adjacent to that which has been cleared of logs in tower logging; done by changing the tailhold.

Slash – debris left after a logging operation.

Side – A logging operation, specifically the place where logging is actually occuring.

Springboard – A board with a metal tip, which loggers use as steps to climb a tree – using notches cut in the tree stump.  They use the boards as a platform to cut the tree above the swell of the butt.

Stumpage – the price paid to the owner for a tree or trees as they stand on the stump.

Strawline – Small, light cable used for rigging tower lines.

Sustainable Yield – the practice of harvesting each year the equivalent of what you are growing. Therefore, you could log forever – say on a 100 year rotation on 100 acres – one acre each year forever.

Tailhold - A sturdy stump or tree used to support tower guy lines or yarding lines.

Turn – A load of logs which is dragged to a landing by a tower (yarder) or tractor.

Yarder – A logging tower, with winches and cables which , which drags or lifts logs to the landing.
