Three mining rights have expired and one remains active (in the northern and highest part of the island) but without being operated (https://georep.nc/explorateur-cartographique). Thanks to its isolation and to the small concession, there should be no mining threat in the near future. The main current threat to the biodiversity of the island is anthropogenic fire that is regularly set up. Even though the Vulcain portal (http://geoportail.oeil.nc/alerteincendies/) does not reflect this status, the fire threat is high and at least a large wildfire impacted the island in
