Log/remove trees within forests: effects on understory plants
A replicated, randomized, controlled study in 1993-1996 in boreal forest in Manitoba, Canada (Kembel et al. 2008) found no effect of cutting on plant cover and diversity. Total plant cover (uncut: 89-132%; harvest to stump: 78-107%; full tree removal: 76-103%), and plant species richness/2 m2 plot (uncut: 12-19; harvested to stump: 12-18; full tree removal: 12-20) and diversity (Simpson's index uncut: 3.9-6.0; harvested to stump: 4.4-3.0; full tree removal: 4.5-6.3) were similar between treatments. In 1993, three plots (30 × 100 m) of each uncut, harvested to stump and full tree removal (harvested trees completely removed) treatments were randomly applied in each of six blocks. Plant cover was measured in six subplots (5 × 5 m) within each plot (total of 324 subplots). Species richness and diversity were determined in a 1 × 2 m quadrat in each subplot. Data were collected in 1996.
