The greatest threat to Palaquium impressionervium is from the expansion of human settlements and extensive habitat degradation. Over 24% of the tree cover within its range has been lost between 2000 and 2016. The tree cover loss, and by extension population decline, would likely be greater than 30% if calculated over three generation lengths rather than 16 years. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2018)[

].
We do not have any more specific information on the wood of this species, but it belongs to a group of timbers collectively called 'Bitis'. The general description of bitis wood is as follows:-
The heartwood is red-brown to purple- or chocolate-red-brown; it is sharply demarcated from the yellow-brown to purple-grey-brown sapwood. The texture is moderately fine and even, with straight or shallowly interlocked grain. The wood is strong, heavy and durable. It is very difficult to treat with preservatives.
It is slightly difficult to difficult to resaw, easy to slightly difficult to crosscut. Planing is slightly difficult but the planed surface is smooth. Nailing property is rated as poor. The timber seasons slowly with moderate end-checking, splitting and surface-checking as the major sources of defects. Shrinkage is high. The timber is likely to be fairly difficult to dry. The wood is suitable for all forms of heavy construction, bridges, wharves, piers, piling, posts, railway sleepers, parquet flooring and heavy flooring.
Bitis is essentially a Peninsular Malaysian name. In Sabah and Sarawak, the timber is not differentiated from the lighter species of Madhuca and Palaquium, and they are all sold together as nyatoh.
