Responses of natural and artificial pin oak (Quercus palustris) reproduction to a sequence of silvicultural release treatments in bottomland hardwood forests in southern Missouri

•Survival of bareroot pin oak seedlings increased with initial basal diameter.•Understory release had no benefit to planted pin oak seedlings.•Oak seedlings dominated small natural regeneration but did not recruit.•Shelterwood harvest increased growth of planted pin oaks but released competitors.•Selection harvest also increased growth of pin oaks with less competitor release.
