Previously, this species was assessed as VU (c2a), but now that more is known about its range and population size, it can be re-assessed as LC. However, it should be noted that there is considerable morphological variation in N. fusca throughout its range, and it is feasible that further taxonomic research could result in the taxon being divided into multiple species. If this eventuates, a new assessment will be required.

Population [top]

Population:The population of Nepenthes fusca is very, very large and is impossible to estimate precisely, as it occurs on almost all mountains higher than 1000 m in Sarawak and Sabah. Furthermore, many plants are epiphytic and are not easily seen from the ground.
Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Found in mossy forests on ridge tops at 500-2000 m alt.
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: Nepenthes fusca is cultivated by enthusiasts of Nepenthes, but is not of interest to other horticulturists. It has no other known uses.

Threats [top]

Major Threat(s): Small numbers of plants are collected for trade and some habitats are being cleared for mining, roadworks and other developments. However, the vast majority of subpopulations of this species occur on remote mountain peaks and at this time, none of these threats is considered significant, particularly as N. fusca is capable of colonising disturbed sites.

Conservation Actions [top]

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