Log/remove trees within forests: effects on understory plants
A replicated, randomized, controlled study in 1952-1991 in temperate broadleaf forest in Wisconsin, USA (Kern, Palik & Strong 2006) found no effect of cutting on ground layer plant species richness and diversity. For spring and summer flowering plants, species richness (1-6 species/150 m2 and 1-18 species/1 m2 respectively) and diversity (Shannon's Index 0.57 and 0.71 respectively) were similar between treatments. Six treatments (1ha): diameter-limit cut (5.3 m2/ha residual basal area, applied in 1952); shelterwood cut (9.2 m2/ha residual basal area, applied in 1957); three levels of individual tree selection: light (20.6 m2/ha residual basal area), medium (17.2 m2/ha residual basal area) and heavy (13.8 m2/ha residual basal area), applied in 1952, 1962, 1972 and 1982; and uncut, were randomly replicated in three blocks. In 1991, spring ephemeral species were monitored in five 10 × 15 m plots and summer flowering species in eight 1 m2 plots in each treatment.
