Grevillea mondorensis, commonly known as "Rince-bouteille du Mont-Dore", is an endemic shrub only known from Mont-Dore at the south of the Grande Terre. It occurs in scrubland (maquis) on ultramafic substrate at an altitude range of 100 and 500 m asl. The population size is estimated to be less than 50 mature individuals and field prospections indicate a species with a very low regeneration. The main threats are uncontrolled bushfires that contributed to the decline of the habitat quality. Its area of occupancy (AOO) and extent of occurrence (EOO) being both estimated to 16 km², while the number of location is estimated to be one. Grevillea mondorensis is therefore considered Critically Endangered Critically Endangered (CR) B1ab(iii,v);C2a (i,ii); D , with an estimated decline of all the concerned subcriteria.
