Plural of grubbery: places associated with grubbing (digging in soil) or the practice of searching, digging, or working in dirt.
From 'grub' (to dig, from Old English origins, possibly meaning to root around like a pig) plus '-ery' (a place or activity associated with something).
Colonial Australian settlers coined this term for the rough, undignified work of clearing land and literally grubbing up roots and stumps—it became a surprisingly poetic way to describe the physical brutality of building civilization.
