Weinmannia ouaimensis is an endemic small shrub restricted to Roches Ouaïème on Grande Terre in New Caledonia. It is found in a shrubland at rather high altitude on volcano-sedimentary substrate. The main threats impacting this species come from bushfires which may directly impact this short vegetation. Its area of occupancy (AOO) and extent of occurrence (EOO) being both estimated to 8 km², Weinmannia ouaimensis is considered Critically Endangered (CR) using criteria B1ab(iii,v)+2ab(iii,v) with an estimation of one location and a decline of habitat quality and number of individuals.
This species is restricted to Roches Ouaïème on Grande Terre in New Caledonia.
This species is known of a single population.
It is found in a shrubland at rather high altitude (750-920 m asl) on volcano-sedimentary substrate.
The main threats impacting this species come from bushfires which may directly impact this short vegetation.
Protected species by legislation in province Nord, this species is not present in any protected area. As this species is threatened by bushfires, its stations must be included in the maps of Sécurité Civile. The area of Roches de la Ouaïème hosts numerous narrow-endemic species. This species would benefit from a properly protected and managed area. Information panels are suggested. It is recommended to experiment ex-situ conservation actions (seeds banking, nurseries and ex-situ plantations).
