Use shelterwood harvesting
A replicated, controlled study in 2001-2009 in temperate mixed oak forest in Pennsylvania USA (Brose 2011) found that shelterwood harvest treatments increased the survival of oak Quercus spp. seedlings. The number of surviving black oak Quercus velutina and northern red oak Q. rubra seedlings/32 m2 plot was highest in complete harvest and large-scale harvest plots (180-220), lower in preparatory cut plots (100-150) and the lowest in uncut plots (25-50). The number of surviving chestnut oak Quercus montana seedlings was higher in the three cutting treatments (120-180) than in uncut plots (25). The number of surviving white oak Quercus alba seedlings was the highest in complete harvest plots (200), lower in large-scale harvest plots(150) and the lowest in preparatory cut and uncut plots (10-50). Four treatments: uncut, preparatory cut (harvest of intermediate trees), large-scale harvest and complete harvest were replicated at each of five sites. Monitoring was in four 8 × 4 m plots in each treatment, each planted with 400 seedling of one of the four oak species.
