Red List Status -Vulnerable (VU) , assessed in 21/07/2016
Geissois velutina is an endemic shrub/tree of the south of Grande Terre in New Caledonia. It is found in dense humid forest at low, mid and high altitude on ultramafic substrate. The main threats impacting this species comes from habitat fragmentation caused by bushfires and by the proximity ot the Vale NC industry installations with one subpopulation. Its area of occupancy (AOO) and extent of occurrence (EOO) being estimated respectively to 60 and 703 km², Geissois velutina is considered Vulnerable (VU) using criteria B1ab(iii)+2ab(iii) with an estimation of 10 locations and an estimated decline of the habitat quality.
Geissois velutina is restricted to the south of Grande Terre in New Caledonia.
This species is never abundant. 10 subpopulations are known.
It is found in dense humid forest at low and mid altitude in Plaine des Lacs and Rivière Bleue, at high altitude in Koghis, Dzumac and Montagne des Sources, always on ultramafic substrate.
The main threats impacting this species comes from habitat fragmentation caused by bushfires and mining activities. We notice the proximity ot the Vale NC industry installations with one subpopulation (Forêt Nord) which makes an obvious threat.
Unprotected by legislation, this species is found in numerous protected areas : Vallée de la Thy, Montagne des sources, Haute Dumbéa, Massif du Kouakoué, Haute Yaté, Foret Nord, Rivière bleue, Haute Pourina, Pic du Pin. it is recommended to follow-up populations as there are few individuals. Protecting legally this species (on the Code de l'Environnement of province Sud) would be beneficial.
