Understorey vegetation is undeveloped
due to the dense canopy closure. The average stand age
was 30 years in 1996 with the stand density of 3800 stems
ha1, and basal area of 19.6 m2 ha1. Average tree height
and circumference (at 1.3 m) were 12.7 m and 227 mm in
1996, respectively (Granier et al., 2000). Thinning activity
was undertaken in 1999.
