Arthrocereus glaziovii has a small range (extent of occurrence ca 1,000 km2), it grows in small subpopulations and only on canga, which is an iron rich rock historically mined in the area. The whole area where the species occurs is affected by mining. There is a continuing decline in the subpopulations unlikely to cease. Hence, it is listed as Endangered under criterion B1ab(iii).
