Red List Category & Criteria: Critically Endangered B1ab(iii,v) ver 3.1
Year Published: 2013
Date Assessed: 2011-05-03
Assessor(s): Faundez, L., Walter, H.E., Guerrero, P. & Avilés, R.

Justification:
Copiapoa ahremephiana has an extent of occurrence of approximately 82 km2. It is known from one location that is subject to different threats that are causing continuing declines and decreasing habitat quality. These threats consist of extended droughts, illegal collection, and attacks of beetles that eat the plants.

Geographic Range [top]

Range Description:This species is endemic to Chile, where it occurs in the low part of Botija Valley and the area between there and the sea (Hunt et al. 2006), at elevations between 0 and 800 m asl. Its extent of occurrence is estimated to be 82 km2.

Population [top]

Population:The species is abundant, but some of the populations are deteriorating due to drought and pests (Coleoptera).
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Yes
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species grows in coastal hills (lomas costeras), in extremely dry areas with very low rainfall. The dry season lasts eight to 12 months and in some years it is possible to have no rainfall at all. From the coastal fog (camanchaca), the plants obtain water mainly from condensation (Belov 2005). The species grows close to populations of Copiapoa solaris and Copiapoa atacamensis.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The species is used as an ornamental for specialized collections outside Chile.

Threats [top]

Major Threat(s): The major threats are illegal collection and invertebrate predators (Coleoptera) that eat the plants from the inside out. However, the extent of the damage to the population is unknown. Another threat is drought, presumably worsening due to global climate change.

Conservation Actions [top]

Conservation Actions: The species does not occur in any protected areas.
