The tree is harvested from the wild for local use of its wood.
Despite the disjunct ('fragmented') nature of the global population in four localities, there is no sign of a decline in the past or present. It seems likely that the disjunction is a result of contraction, but this must have happened long ago and it is doubtful that human activities played a role in this. There is no commercial exploitation or degradation of the habitat at present. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[

The wood of the various Dacrydium species is jointly known as 'sempilor'. The basic description is as follows:-
The heartwood is buff in colour, sometimes with a pink tinge or golden brown; it is not differentiated from the sapwood. The texture is very fine and even; the grain straight. The wood is reputed to be weak; it is light to moderately heavy in weight; it is not durable and is subject to drywood termite attacks. It seasons well without serious degrade; shrinkage is very high; a slight to moderate twisting may occasionally occur. The wood works very easily; it produces a smooth and somewhat lustrous surface; gluing, nailing and peeling properties are satisfactory. A softwood, it should be suitable for decorative works and can be used for panelling, partitioning, veneers, plywood, joinery and furniture making[
