It occurs in humid forest at an altitudinal range 100-750 m asl. Its area of occurrence (EOO) and area of occupancy (AOO) are respectively 76 km² and 20 km², while the number of locations is equal to four. Main identified threats are linked to tourism, recreation areas development (Koghi) and habitat degradation caused by invasive species (feral pigs) allow us to project a continuous decline in the quality and surface of habitat. Corybas pignalii is considered Endangered EN: B1ab (iii)+B2ab(iii).
