Abstract

Regeneration patterns were studied in low-site oak and oak-pine stands in southeastern New England after gypsy moth defoliations in 1981-1982. Three oak and three oak-pine stands where tree mortality was high (HM) and two oak and two oak-pine stands where tree mortality was low (LM) were used. Salvage logging had occurred in the three HM oak stands. Despite average basal area losses of 68% in HM oak and 46% in HM oak-pine stands, oaks dominated overstories in 5 of the 6 HM stands. Oaks dominated overstories in all LM oak and oak-pine stands. Combined totals of oak saplings and more vigorous forms of regeneration (stump sprouts and seedling sprouts) indicated numbers sufficient to regenerate oaks in all stands. White pine seedling and sapling totals (561/ac) in HM oak-pine and 858/ac in LM oak-pine stands should ensure the continued strong presence of pine in the oak-pine stands. Results of regeneration surveys suggest that the future composition of the oak and oak-pine stands studied is unlikely to change. North. J. Appl. For. 12(3):109-114.
