An individual really good at treeplanting. A person that consistently plants a high number of quality planted trees with proper plug or root placement, 1" of exposed mineral soil with the correct 9'x9' spacing. Predominantly used in Western Canada in the treeplanting world. Typically there can only be one ScreefMaster in a camp.
Holy Cow! I heard that Archer had 1,800 trees planted today by the end of his run. He really is a Screefmaster. If he keeps hiballing like that there won't be anymore trees left.
