Use clearcutting to increase understory diversity
A replicated, controlled, before-and-after study in 1992-1993 in bottomland hardwood forest in Texas, USA (Messina et al. 1997) found that clearcutting increased tree species diversity. Shannon's index of diversity for trees <4 cm DBH increased in clearcut plots (before: 2.21; after: 2.33), but remained similar in partial-cut (before: 2.30; after: 2.33) and control plots (before: 1.95; after: 1.98). In 1992, three treatment plots (8.1 ha): clearcut (all woody vegetation cut), partial-cut (50% of basal area cut) and control (uncut) were replicated in three blocks. Data were collected in 1993 in nine subplots (40 m2) in each plot.
