|Scientific Name:||Nageia maxima|
|Species Authority:||(de Laub.) de Laub.|
Decussocarpus maximus de Laub.
Nageia maximus (de Laub.) de Laub. [orth. error]
|Red List Category & Criteria:||Endangered B2ab(ii,iii,iv,v) ver 3.1|
|Reviewer(s):||Mill, R. & Farjon, A.|
Nageia maxima was previously assessed in 1998 as Vulnerable under the D2 criterion (restricted distribution and potential threat). Since then there has been widespread conversion of peat swamps (its main habitat) throughout most parts of its range. Consequently a decline in the area of occupancy (estimated to be less than 500 km2), the quality of habitat and number of locations, subpopulations and individuals is inferred and an assessment of Endangered under the B criterion is justified. Further expansion of palm oil plantations could lead to an upgraded assessment of Critically Endangered in the near future.
|Range Description:||Currently known from two locations in Sarawak (Malaysia): the Mujong River drainage and Bako National Park. It is likely that it has, or had, a wider distribution within the lowlands of Sarawak. The area of occupancy is estimated to be considerably less than 500 km2.|

|Population:||No specific information has been recorded for this species; other species in the genus generally occur in relatively small stands. The total population is likely to be decreasing due to the conversion of peat swamps to oil palm plantations.|
|Habitat and Ecology:||An understorey tree or shrub of peat-swamp and lowland forest.|
|Use and Trade:||No specific uses have been recorded for this species.|
|Major Threat(s):||Widespread conversion of peat swamps for palm oil plantations is the primary threat facing this species. Urban expansion and infrastructure developments are secondary threats while past logging of lowland forests will also have indirectly impacted this species.|
|Conservation Actions:||Nageia maxima is recorded from Bako National Park. This park is relatively small (2,727 ha) and isolated from other areas of natural vegetation.|
