Population [top]
Population: This extremely widespread species usually occurs in localized stands or as scattered individuals. The total population size is unknown although it is likely to have declined through habitat loss.
Current Population Trend: Decreasing

Habitat and Ecology [top]
Habitat and Ecology: This is the most widespread species in the genus Nageia and perhaps also one of the most truly tropical of all conifers, as it occurs near sea level in Dipterocarp forest on the equator. It is scattered but often common in primary rainforest with canopy heights to 50 m or more, and occurs from lowlands to montane forested ridges at 2,100 m a.s.l. In the lowland rainforest it develops a straight bole lifting its crown into the canopy. It is, however, not a long-lived emergent and boles usually are rather slender without buttresses indicating modest longevity. Unlike Agathis (Araucariaceae) it is not gregarious. Kerangas (forest on leached sandy soils) can have both species, as well as other conifers like Dacrydium, Dacrycarpus, Falcatifolium falciforme, and Sundacarpus amarus, mixed with Myrtaceae and other angiosperms that have adapted to poor nutrient situations. In China, N. wallichiana occurs in evergreen subtropical forest dominated by Castanopsis and/or Quercus on hillsides but not in high mountains. In margins of peat swamps, in mossy forest on sandstone plateaus of Sarawak, and on mountain ridges with clay or sand amongst rocks it becomes stunted. In New Guinea it is sometimes associated with Araucaria and Podocarpus in mixed conifer forests, which also have several species of Fagaceae, especially in the genus Castanopsis.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 25
Use and Trade [top]
Use and Trade: Nageia wallichiana is a highly valued timber tree, especially where it grows into tall, straight trees with a long, clear bole. It is traded as podocarp wood. Long timber is sawn into planks for construction (mainly house building); other uses of the wood are plywood, veneer, interior finishing, furniture making, and sometimes (Fly River, Wagu, Papua New Guinea) the construction of small canoes. Small stems are used for household utensils, drumsticks, etc. Leaves are used in Viet Nam as a cure for coughs; decoction of leaves taken orally by the Nicobarese as treatment for painful joints (Pandey et al. 2009). It is not grown in cultivation other than in a few botanic gardens.
Threats [top]
Major Threat(s): Logging and forest clearing must have had and still have a negative impact on the total population size of mature trees, but it is virtually impossible to quantify this over such a large and diverse area.
Conservation Actions [top]
Conservation Actions: This species occurs in several protected areas across its wide range.
