The oak/northern hardwoods forest association can be maintained if large oak seedlings are present prior to any natural or planned disturbance to the overstory. If only small openings or no openings in the canopy are created this association will gradually convert to northern hardwoods. If larger openings are created or the overstory is completely removed within a short period of time and oak seedlings are not established, this association will gradually convert to Allegheny or Appalachian hardwoods.
