Although many sites where Nepenthes ampullaria grows have been severely degraded in recent years, the effect of habitat degradation on this species has yet to be determined, and mature plants may persist in degraded sites for decades. Given this species' very large geographical range, vast population size, and lack of evidence to suggest significant, continuing declines in AOO/EOO, it is assessed here as LC.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Nepenthes ampullaria has a unique geographical range within Nepenthes, being widely distributed in the Sunda region (Borneo, Sumatra, Malay Peninsula), and also in New Guinea, but nowhere in between. It is primarily a species of lowland swamp forests, but has been found at altitudes as high as 2100 m.
Countries occurrence:
Brunei Darussalam; Indonesia (Kalimantan, Papua, Sumatera); Malaysia (Peninsular Malaysia, Sabah, Sarawak); Papua New Guinea; Singapore; Thailand
Additional data:
Estimated area of occupancy (AOO) - km2:1300Continuing decline in area of occupancy (AOO):Unknown

Population [top]

Population:The size of the Nepenthes ampullaria population cannot be estimated accurately, as it is so large and widespread.
Current Population Trend:Unknown
Additional data:
Number of mature individuals:1000000Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Occurs in damp, shady sites in peat swamp and heath forests (primary, secondary and anthropogenic) in Sumatra, Peninsular Malaysia, Singapore, southern Thailand and Borneo. In New Guinea, it grows in Araucaria forests, secondary forests on nutrient-deficient substrates, open microphyllous vegetation, or swamp grassland. Although the species has been recorded from sea-level to 2,100 m altitude, nearly all subpopulations occur below an altitude of 100 m.
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: Nepenthes ampullaria is in cultivation, where it is popular among enthusiasts of the genus. However, its appeal is limited to this specialized market. The stems have been used as twine in traditional societies in Borneo, and rice is sometimes cooked in the pitchers. The fluid from unopened pitchers has been used to treat minor irritations to eyes. It has no other known uses.

Threats [top]

Major Threat(s): Threats to Nepenthes ampullaria are many and varied, but at the population level, none appear to be significant at present.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation actions in place at present. The species is currently listed on CITES Appendix II.
