Use clearcutting to increase understory diversity Forest Conservation

A before and after study in 1995-2003 in subtropical forest in Okinawa Island, Japan (Wu et al. 2013) found no effect of clearcutting on tree species richness and diversity. Species richness/plot (before: 33; after: 50) and Shannon's diversity (before: 4.0; after: 4.8) in cut plots were higher after treatment. However, species richness (before: 24; after: 45) and diversity (before: 3.4; after: 4.5) were higher in uncut plots. Data were collected before (January 1995) and after treatment (2003) in five clearcut (in February 1995) and five uncut plots (10 × 10 m) established within a 4,000 m2 forest section.
