  1. Use clearcutting to increase understory diversity

    A replicated, randomized, controlled study in 1993-1995 in temperate broadleaf forest in Indiana, USA (Jenkins & Parker 2000) found that cutting treatments increased species richness but not the diversity of herbaceous species and low plants. Species richness (in 4 m2 quadrat) was higher in clearcut (43) and group cut (47) compared to single tree cut (36) and uncut plots (34). Diversity (Shannon's index) was similar in all treatments (2.6-2.8). One plot (100 m2) was established in each of 12 clearcut, 16 group selection (cutting in groups, 0.1-1.6 ha), 17 single tree selection cuts (cutting single trees, 0.005-0.012 h) and 12 uncut (>80 years) treatment plots. Data were collected in four quadrats (4 m2) in each plot
