Dacrydium nausoriense is a valuable timber species in Fiji that has been heavily exploited. It has a very restricted distribution  and the estimated area of occupancy is well within the threshold for Endangered under criterion B. It is known from two locations and there is a continuing decline at least in the quality of habitat and probably the number of mature individuals.
1998 Endangered

Geographic Range [top]

Range Description: D. nausoriense is restricted to two locations within Fiji: one in the Nausori Highlands in western Viti Levu and the second at Sarava on Vanua Levu. The estimated area of occupancy is much less than 500 km2.

Population [top]

Population: Two subpopulations are currently known. On Viti Levu all known stands are within several kilometres of each other and are considered as a single subpopulation within the context of the IUCN Red List Guidelines. The second subpopulation is on Vanua Levu. The number of mature individuals is unknown.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Grows in sub-montane forest  (300-600 m asl); often associated with regrowth in logged forest, abandoned garden sites or the margins of forest with anthropogenic grassland. The rainfall ranges from 2,000 to 3,500  mm per year with a distinct dry season from June to October. Reported to be slow growing, especially when young.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Highly valued for timber that is used for general construction and carpentry.

Threats [top]

Major Threat(s): The primary threats are overexploitation for timber and loss of habitat due to forest clearance for agriculture and pastoral activities.

Conservation Actions [top]

Conservation Actions: Currently this species is not known to occur in any protected areas although some areas within its range have been identified as priority areas for conservation (Olson et al. 2009). There is an urgent need for further field surveys to establish the size of the remaining population, its distribution and status. Dacrydium nausoriense is listed under Schedule 2 of Fiji's Endangered and Protected Species Act (2002) which provides some regulation of its exploitation.
