Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2013
Date Assessed: 2010-12-15
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P. & Mill, R.
Known from only one locality and its type specimen (Brass 12659, holotype L), but due to poor collecting records from the area nothing can be concluded from this as to rarity, population size, and so on. The fact that is has been described in 1969 and no subsequent collections have been made is due to its obscurity as a species, which is not commonly known to botanists who might visit the area. Rather than list it as Data Deficient we believe this species should be flagged as Near Threatened as it is surely very rare and restricted (so almost qualifies for listing as threatened under criteria B and D). As a canopy tree in rain forest it may be subject to logging.
Previously published Red List assessments:
2007 Near Threatened (NT)
1998 Rare (R)
1998 Data Deficient (DD)

Geographic Range [top]

Range Description: Endemic to a small area in the Central Highlands of Papua (Irian Jaya), Indonesia. This species is only known from a few herbarium collections made in 1939 at a location 18 km southwest of Bernhard Camp on the Idenburg River, a remote locality in western Irian Jaya. The extent of occurence is less than 100 km² and are of occupancy less than 10 km². Further field work could reveal a more substantial distribution.
Countries occurrence:
Indonesia (Papua)
Estimated area of occupancy (AOO) - km2: 9
Number of Locations: 1
Lower elevation limit (metres): 2150
Upper elevation limit (metres): 2200

Population [top]


The population is presumably small if it indeed occurs in only one locality, but no quantitative data are available.

Current Population Trend: Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology: Dacrydium spathoides is known from a single locality on the Idenberg River where it forms a canopy tree in moist, mossy montane rain forest at an altitude of 2,150-2,200 m a.s.l.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: No
Generation Length (years): 40

Use and Trade [top]

Use and Trade: The timber of this tree is possibly used for construction (house building), but its very localized occurrence means that no specific data are available.

Threats [top]

Major Threat(s): No threats are known or have been reported.

Conservation Actions [top]

Conservation Actions: The single locality known does not occur within a protected area.
