General Information

Dacrycarpus expansus is an evergreen tree that can grow from 9 - 25 metres tall, occasionally reaching 30 metres. The bole can be 22 - 58cm in diameter[, ].
Little is known about the uses of this species; it is assumed to be logged on a small scale for local use mainly, and if traded, would be called 'podocarp' together with other species of Podocarpus logged in the Central Highlands of New Guinea[].
This species is predominantly distributed in high elevation swamp grassland to cloud forest ecotone, where no commercial logging takes place. Trees at lower elevations may be more at risk of being logged, but quantitative data are very difficult to obtain as no distinction is made between the species of Dacrycarpus or even other podocarps when logged.The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[].

Other Uses

Little is known about the uses of this species; it is assumed to be logged on a small scale for local use mainly[].

The wood from the various species of Dacrycarpus is very similar and is generally lumped together as 'podocarpus wood'.. The only description we have is for Dacrycarpus imbricatus, which is as follows:-

The wood is fine-grained, resistant to termites and insects, easy to work[]. Of moderate quality, it is used for construction, furniture making, boxes, plywood and construction timber[, ].

Propagation

The aril surrounding the seed possibly contains germination inhibitors, and so should be removed from the seed as soon as possible[]. Sow the seed in light shade in a nursery seedbed. Germination can take from 2 - 13 weeks[].
Rooting of cuttings can be done from coppice material. In a test 7 - 10cm long cuttings were root dipped in ABT. After 3 months 80% of the cuttings had rooted successfully[].
