Geographic Range [top]

Range Description:Nepenthes gracilis is very common and widespread in disturbed lowland habitats in Borneo, Sumatra and the Malay Peninsula. There is a single record from Sulawesi.

Population [top]

Population:Nepenthes gracilis is probably the most abundant Nepenthes species in the Sunda region, colonising open, disturbed sites throughout Malaysia, Brunei and many parts of Sumatra and Kalimantan. The population is impossible to estimate accurately, due to its very large size.
Current Population Trend:Increasing
Additional data:
Number of mature individuals:1000000Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:No
Extreme fluctuations in subpopulations:UnknownAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:Nepenthes gracilis primarily grows in secondary vegetation on highly degraded, nutrient-deficient substrates. It also grows in lowland peat-swamp forest and heath forest, swamp edges, on sandstone or ultrabasic soils; from sea level to 1200 m altitude, but nearly all subpopulations occur below 800 m.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: Nepenthes gracilis is in cultivation and is grown extensively by enthusiasts of Nepenthes. It is easy to cultivate and there is little trade in plants collected from the wild. It has no other known uses.

Threats [top]

Major Threat(s): There are no significant threats to Nepenthes gracilis at present. Many subpopulations are destroyed when suburban and rural areas are cleared for development or plantation agriculture, but these are readily replaced by new colonisations of recently-disturbed or cleared ground. The species appears to prosper in regions that are disturbed by people.

Conservation Actions [top]

Conservation Actions: The species is listed on CITES Appendix II. There are no other direct conservation measures at present. Some subpopulations occur within Protected Areas, but these are often comparatively unhealthy, as the species appears to thrive in recently disturbed habitats, which are scarce within Protected Areas.
