Log/remove trees within forests: effects on mature trees
A site comparison study in 1990-1998 in tropical rain forest in Papua New Guinea (Lindemalm & Rogers 2001) found that high intensity logging decreased tree species diversity. Species diversity was lowest in high intensity logging (Shannon-Weiner's index: 0.85) and similar in low intensity logging (1.08) and unlogged plots (1.14). Tree species diversity was calculated in six 0.2 ha plots (200 × 10 m) in each of high intensity logging (20 m2/ha of basal area removed using conventional high impact logging technics in 1990-1991), low-intensity logging (4.2 m2/ha of basal area removed using low impact portable sawmill in 1992) and unlogged sites. Data were collected six years after treatments.
