Past Present Future 1 Habitat Loss/Degradation (human induced) 1.1 Agriculture 1.1.1 Crops 1.1.1.1 Shifting Agriculture 1.1.1.2 Small-holder farming 1.4 Infrastructure development Conservation Measures There are no specific conservation measures in place for this species. It may benefit from existing protected areas, for example it is recorded from the Op Luang National Park in Thailand. However, much of its range falls outside such areas. Further research is needed to establish its current habitat status and threats and also current population numbers and range. It was not found in available lists of seed bank and botanic garden species.

Food - human In Laos the leaves are used as an infusion in the place of tea and is also used to cure fish (Dy phon et al 1994) Trend in the level of wild offtake/harvest in relation to total wild population numbers over the last five years: Trend in the amount of offtake/harvest produced through domestication/cultivation over the last five years: CITES Not listed IUCN Red Listing Red List Assessment: (using 2001 IUCN system) Least Concern (LC) Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX Is the species Possibly Extinct? Possibly Extinct Candidate? Rationale for the Red List Assessment The extent of occurrence (EOO) for this species exceeds the critical threshold. The estimated area of occupancy (AOO) and inferred population also exceed the thresholds. It is assessed as Least Concern (LC). However, the forest habitat of this species faces ongoing threats, and research is needed to establish the current population and habitat status.
