General Information

Palaquium herveyi is a tree growing up to 45 metres tall.
The tree is harvested from the wild on a commercial basis for its wood, which is traded as 'Nyatoh'[].
Palaquium herveyi has been collected in protected areas and the extent of occurrence (EOO) is large. The habitat is, however, under threat - 20% of the tree cover within the EOO has been lost from 2000 to 2016 and based on this there is a suspected population decline. The tree cover loss and the population decline would most likely be 25-30% if
calculated over three generation lengths (60-150 years) rather than 16 years. The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2018)[].

Wood[].
We do not have any more specific information on the wood of this species, but it belongs to a group of timbers collectively called 'Nyatoh'. The general description of nyatoh wood is as follows:-
The heartwood is a dark pink to a red-brown; it is clearly demarcated from the 4 - 9cm wide band of lighter-coloured sapwood. The texture is medium; the grain straight or interlocked, sometimes wavy. The wood is light in weight, soft to moderately hard; strong, somewhat durable, being resistant to dry wood borers, moderately resistant to fungi but susceptible to termites. It seasons somewhat slowly, with a high risk of checking and distortion; once dry it is stable in service. There is a very variable content of silica according to the species, but in general the wood has a high blunting effect so stellite-tipped and tungsten-carbide tools are recommended; nailing and screwing are good, but require pre-boring; gluing is correct. The wood has a range of applications, including for high class furniture and cabinet making, solid doors, panelling, joinery, parquet flooring, boat decking, light carpentry, turnery, moulding and veneer[, ].
