État de la populationExpert
This species is described as abundant in the Pondok-Tanjung, Gunung Bongsu and Bukit Panchor Forest Reserves, otherwise there is no information on population size but as some populations have been lost is must be considered to be decreasing. Some subpopulations have been lost to development and forest clearance, and a continuing decline in the number of subpopualtions is inferred.

Description complète des menacesExpert
This species is threatened by clearance of forest and some of the areas where it occurs have already been converted to oil palm plantations. Populations are known from three Forest Reserves, which means that they should be secure. However, this species is also threatened by logging, highway construction or widening projects and urban expansion; it is not certain that the protection provided by Forest Reserves will be sufficient. It is also threatened by collection from the wild for the plant trade.

Habitats préférentiels (classification IUCN)

  • 5_1Wetlands (inland) - Permanent Rivers/Streams/Creeks (includes waterfalls)
  • 5_4Wetlands (inland) - Bogs, Marshes, Swamps, Fens, Peatlands
  • 5_7Wetlands (inland) - Permanent Freshwater Marshes/Pools (under 8ha)
Mesures de conservation recommandéesExpert
There are no conservation measures in place specifically for this species. Some populations have already been lost to development and forest clearance, but it is known to occur in three Forest Reserves: Pondok-Tanjung FR in Penang State, as well as Gunung Bongsu FR and Bukit Panchor FR in Kedah State. There is a need for surveys to establish a current assessment of the conservation condition of populations outside Forest Reserves, combined with monitoring of all populations. Two new localities to the north and south have been reported, but not officially documented.
