Larridon, I. et al. (2018). Investigating taxon boundaries and extinction risk in endemic Chilean cacti (Copiapoa subsection Cinerei, Cactaceae) using chloroplast DNA sequences, microsatellite data and 3D mapping. Kew Bulletin 73: 55.

According to the IUCN Red List, the conservation status of Copiapoa cinerea (circumscription including C. cinerea subsp. cinerea, subsp. columna-alba and subsp. haseltoniana) is LC (Faundez et al. 2013). Using the species delimitation as accepted by Larridon et al. (2015) and this study, even the total EOO and AOO values for C. cinerea, indicate that it may be considered as EN if conforming to additional conditions listed in Criterion B (IUCN 2012). Although Schulz & Kapitany (1996) and Guerrero et al. (2010, 2012) estimated that, overall population trends are negative due to generally low numbers of seedling recruitment, high percentage of senile individuals, and declining habitat quality, this negative trend is not followed by C. cinerea subsp. columna-alba. As a species therefore, the conservation status can be maintained as LC.
