Hopea beccariana is a large tree species. It is found in the mixed Dipterocarp forests of Thailand, Malaysia, Sumatra and Borneo. The species is globally assessed as Vulnerable. There has been between a 30 and 50% population reduction in the last three generations and decline is projected to continue at the same rate. The species is in decline as result of the habitat loss and conversion for the expansion of agriculture. Decline also occurs as result of selective logging for timber. Both threats are predicted to impact the species in the future. The species is found within protected areas but only in one ex situ collection. It is recommended further ex situ collections are made and further habitat protection occurs. The harvest and trade of the species should also be monitored.

Population [top]

Population:This species is common on Borneo and in Peninsula Malaysia where it is estimated that there are 560,000 adult stems in the Permanent Reserved Forests (Chua et al. 2010). This species is rare in Thailand. It has a generation length of 100 years. Population is currently in decline. There has been between a 30 and 50% population reduction in the last three generations (300 years) due to the expansion of agricultural areas and exploitation for timber. The species is projected to continue to decline at the same rate.
Current Population Trend:Decreasing

Habitat and Ecology [top]

Habitat and Ecology:This is a large tree species, growing up to 45 m tall (Ashton 2004). It forms part of the upper canopy within lowland mixed dipterocarp rain forest and can also be found on coastal hillsides (Ashton 2004). It shows preference to the deeps soils and growth on ridges (Chua et al. 2010). This species is perennial and deciduous. It is reported that its seed can be dispersed by ants (Lee et al. 2002). The species habitat is declining in both extent and quality.
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):100

Use and Trade [top]

Use and Trade: This tree is a hardwood species used for timber (Mark et al. 2014). Timber of the Hopea genus is generally used for construction, flooring and the production of packaging and storage (ITTO 2017). Wood of this species specifically is used to produce poles used for making fish traps. Danmar, a thick resin, can also be harvested from the trees. This is mostly exported from Indonesian sub-populations and can be used to make torches, for boat caulking and handicrafts (Shiva et al. 1998).

Threats [top]

Major Threat(s): This species is threatened by habitat loss and conversion. Habitat is being cleared for the expansion of agriculture and hence area, extent and quality of habitat are in decline. The species is also at risk from selective logging and exploitation for timber.

Conservation Actions [top]

Conservation Actions: This species is reported from only one ex situ collection (BGCI 2017). Further ex situ collections of this species should be made which are representative of the species entire range. The species occurs in protected areas. It was previously assessed as Critically Endangered (1998). The harvest and trade of the species requires monitoring and restriction if necessary, to ensure sustainable use of remaining population. Further habitat protection should be offered to the species to prevent future decline.
