Abstract: An increased interest in the use of group selection harvesting in the Central Hardwood forests has emphasized the lack of scientific information about species response under this uneven-aged management system. Tree regeneration response following group selection harvesting was studied on thirty-six group selection openings on the Naval Surface Warfare Center, Crane Division in southern Indiana. The objectives were to determine whether aspect, age, species group, size of the opening, or their interactions had any influence on the number of stems or average height of the tree regeneration. Two different aspects, three postharvest age classes, and three opening sizes were examined. Yellow-poplar and dogwood were the most abundant stems ≥ 2.5 cm dbh, and dogwood and cherry-ash-walnut were the most abundant stems < 2.5 cm dbh. Stem density (< 2.5 cm dbh) was influenced by age, aspect, and the age/species group and aspect/species group interactions. The north aspect and the oldest openings contained the highest number of stems per hectare for stems < 2.5 cm dbh. Age, species group, and their interaction influenced average height for stems ≥ 2.5 cm dbh.
