Habitat and Ecology [top]

Habitat and Ecology:This species has been recorded as epiphytic in mossy forest, or terrestrial in swamps, moist grasslands or on ridge tops. It is usually found at 600-2500 m, but occasionally at lower altitudes (for example, it has been recorded at 40 m at Milne Bay, Papua New Guinea).
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: Nepenthes maxima is widely cultivated by carnivorous plant enthusiasts globally. It has no known uses outside horticulture.

Threats [top]

Major Threat(s): There is no doubt that throughout its vast range, some sites where N. maxima grows are, have been or will be degraded or destroyed by development. However, anthropogenic disturbances are unlikely to significantly reduce numbers of this species in the foreseeable future.

Conservation Actions [top]

Conservation Actions: The species is currently listed on CITES Appendix II, but is not subject to any other direct conservation actions.
