  1. Log/remove trees within forests: effects on mature trees

    A site comparison study in 1958-1997 in tropical rain forest in Malaysia (Okuda et al. 2003) found that logging decreased tree height and canopy size but not their density. Unlogged plots had greater canopy height (logged: 24.8 m; unlogged: 27.4 m), canopy surface area (logged: 19,272 m2/ha; unlogged: 27,845 m2/ha) and crown size of individual trees (logged: 42.9 m2; unlogged: 94.5 m2) compared to logged plots. However, the number of stems/ha was similar between treatments (logged: 6,067; unlogged: 6,418). Data were collected in 1997 using aerial photographs in a 6 ha logged site (all trees >45 cm diameter at breast height removed in 1958) and a 50 ha unlogged site, both divided into 50 × 50 m plots.
