Although Nepenthes papuana remains a poorly documented species, the subpopulation near Tembagapura has been observed in recent years and is known to be reasonably extensive. Coupled with this, the geographical range of the species in Papua is also extensive, indicating that the area of occupancy for N. papuana is likely to be much greater than previously assumed four localities. Although the known range is relatively small, the abundance of this species, its occurrence in disturbed areas and the fact that there appear to be no major threats support listing this species as Least Concern.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Nepenthes papuana has a patchy distribution in Papua Province, Indonesia. It has been recorded on both the north and south sides of the main central ranges and on this basis, it is likely that it has a reasonably wide distribution in Papua Province. However, as most of the sites where it has been reliably recorded are remote, the currently estimated extent of occurrence (EOO) and area of occupancy (AOO) are relatively small.
Countries occurrence:
Indonesia (Papua)
Additional data:
Estimated area of occupancy (AOO) - km2:16Continuing decline in area of occupancy (AOO):No
Extreme fluctuations in area of occupancy (AOO):NoEstimated extent of occurrence (EOO) - km2:16000
Continuing decline in extent of occurrence (EOO):NoExtreme fluctuations in extent of occurrence (EOO):No
Continuing decline in number of locations:No
Upper elevation limit (metres):1300

Population [top]

Population:As few observations of wild plants of N. papuana have been made, it is not possible to estimate the population size. However, it does not appear to be rare in the foothills of Papua Province and is probably stable.
Current Population Trend:Stable
Additional data:
Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:N. papuana grows in stunted forest on nutrient deficient soils at altitudes from sea level up to 1,300 m. It appears to colonize disturbed sites well and may be locally abundant. It is a terrestrial climber, with vines scrambling over shrubs in open areas, or up to the height of the canopy in more closed vegetation.
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: Plants are grown as ornamentals in horticulture.

Threats [top]

Major Threat(s): The pristine habitats where N. papuana occurs are remote. Where it occurs in disturbed sites, it colonizes open, bare ground effectively and does not appear to be adversely affected by habitat disturbances. For these reasons, this species is not considered threatened at present.

Conservation Actions [top]

Conservation Actions: N. papuana is currently listed on CITES Appendix II. At least one subpopulation lies with Lorentz national Park, affording the species some protection. No other species-specific conservation actions are in place.
