Use group-selection harvesting
A replicated, controlled study in oak–pine Quercus–Pinus forest in Maine, USA (Schumann, White & Witham 2003) found no effect of group selection harvesting on species richness and diversity of understory vegetation. Numbers of species/1 m2 (group-selection: 18-34; uncut: 18-25) and diversity (Shannon's index group-selection: 1.7-2.2; uncut: 1.9-2.1) were similar between treatments. Data were collected in 1998 in 40 pairs of group-selection (36-3,393 m2 gaps harvested in 1987-1988) and uncut sites inside a 40 ha study area. Equal number (proportional to the gap size) of 1 m2 plots were monitored in each pair.
