Use shelterwood harvesting
A replicated, controlled study in 1993-1997 in temperate mixed forest in Ontario, Canada (Bellocq et al. 2005) found no effect of shelterwood harvest on the acorn crop of red oak Quercus rubra. Acorn production (unharvested: 29,577; shelterwood: 28,697/plot) and the percentage of acorns damaged by insects (shelterwood: 44%; unharvested: 47%) were similar between treatments. Five shelterwood (trees cut to 50% crown cover) and five unharvested plots (60 m × 60 m) were established in 1993-1994. Acorns were sampled using one trap (1 × 1 m) per 120 m2 of crown cover (total of 86 traps) in August-November 1997.
