Scientific Name: Agathis ovata

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) ver 3.1
Year Published: 2010
Date Assessed: 2009-11-06
Assessor(s): Thomas, P.
Reviewer(s): Farjon, A. & Gardner, M.
Contributor(s): Munzinger, J., Lowry, P. & Jaffré, T.
Justification:
Agathis ovata is assessed as Endangered on the basis of its limited extent of occurrence (2,814 km2), area of occupancy (100 km2), a projected decline extent of occurrence, area of occupancy, the quality of habitat, number of locations and number of mature individuals due to mining activities and fires. Although there are eight general locations known (three more than the threshold for Endangered), there is severe fragmentation of subpopulations due to their geographic isolation, large areas of intervening unsuitable habitat and low dispersal and reproduction rates.
History:
1998 Lower Risk/conservation dependent (Oldfield et al. 1998)
1997 Rare (Walter and Gillett 1998)

Geographic Range [top]

Range Description: Agathis ovata occurs primarily in the Southern Massif with a few occurrences as far north as Kouaoua on the east coast. It occurs from 150 to 1,150 m.

Population [top]

Population: Subpopulations are usually very small (in areas of < 2 ha) and isolated.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Agathis ovata occurs as an emergent tree in open shrublands (maquis) and as a canopy emergent (to 25 m) in angiosperm-dominated (closed) rainforests. It is restricted to ultramafic soils and in the maquis; it tends to be restricted to rocky outcrops.
Systems: Terrestrial

Threats [top]

Major Threat(s): Mining activities and fires are the main threats. The species is capable of establishing and persisting in both rainforest and maquis. Mature trees have some fire resistance but this depends on frequency and severity. Regeneration and general growth rates are very slow.

Conservation Actions [top]

Conservation Actions: Several subpopulations at higher altitudes occur in protected aresa such as the Rivière Bleue Provincial Park, Montagne des Sources and Mt Do.
