Screef is a word used in the treeplanting world, specifically Western Canada, to mean to clear a space using a shovel to expose mineral soil in order to plant a pine or spruce seedling.
"Hey Conrad - I need these trees planted with 9' x 9" spacing and 1' of exposed mineral soil. Make sure everybody screefs good!"
