This taxon is a localized habitat specialist known from two threat based locations. It has an extent of occurrence (EOO) and an area of occupancy (AOO) of 8 km². Population decline has been observed at one of these locations and with ongoing increasing demand for Conophytum species loss is expected to be continuing.
