dipterocarp

Examples

• All

• The current rate of timber harvesting does not appear to be sustainable, particularly in the hill dipterocarp forest where most of the log extraction is now occurring (ITTO 1990).

• For the whole of Borneo, the average annual deforestation rate for 2002-2005 was estimated as 2.2% for peat swamp forest, compared with 1.8% for lowland dipterocarp forest (Langner et al. 2007).

• All sites were located within the mixed dipterocarp forest formation and, therefore, share many of the same genera and families of trees.

• Our research sites are three contrasting mixed dipterocarp forests in Sarawak that have been followed since 1965 (Figure 1).

• Our results show that approximately one-third of the common species, some of which are main canopy dipterocarp species, have unstable populations at the scale of 2.4-3.0 ha, with some increasing in size and many decreasing (Figure 6).

• Three primary forest sites were selected in 1965 by tropical botanist Peter S. Ashton, then on the staff of the Sarawak Forest Department, to represent the range of mixed dipterocarp forest structure found in Sarawak (Figure 2).

• Sixth, the density of dipterocarp seedlings is reduced by logging activity to approximately 10% of the original number and is reduced further by damage caused during silvicultural treatment (Primack et al. 1987c).

• The massive dipterocarp tree can withstand strong winds and heavy rainfall, making it a crucial part of the rainforest ecosystem.

• In Southeast Asia, many local communities rely on the timber from the dipterocarp family for building homes and furniture.

• Researchers discovered that the unique bark of the dipterocarp tree has properties that can help in traditional medicine.
