Scientific Name: Basananthe cupricola
Species Authority: Robyns ex G.A. Levin
Assessment Information [top]
Red List Category & Criteria: Extinct ver 3.1
Year Published: 2012
Assessor/s: Meersseman, A., Faucon, M.-P., Meerts, P., Mahy, G., Malaisse, F. & Ngongo Luhembwe, M.
Reviewer/s: Stévart, T., Dessein, S., Ewango, C. & Gereau, R.
Justification:
Basananthe cupricola was strictly endemic to copper-rich soil (i.e., it is an absolute metallophyte) in Katanga, Democratic Republic of Congo, where it was known from only one location. Its habitat was restricted to steppic savannah in copper outcrops and it was destroyed by surface mining activities. Despite intensive fieldwork in the entire copperbelt region, no individuals have been found since 1980 (Malaisse 10287 BR). Based on these observations, this species is listed as presumed Extinct.

Habitat and Ecology [top]
Habitat and Ecology: This plant was strictly endemic to copper-rich soil (i.e., it was an absolute metallophyte). Its natural habitat was restricted to steppe savanna, where it was found growing in copper outcrops. This habitat, which is naturally enriched with copper, is of rare occurrence.
In the Katangan Copper Belt area, mineralised rocks appear as rounded hills, typically a few tenths of meters above the level of the surrounding non-mineralised areas, and most are typically a few tenths of hectares in area, rarely exceeding 1 km² (Faucon et al. 2010). The distance between nearby hills varies from less than a few hundred meters to more than 20 km (Faucon et al. 2010).
Systems: Terrestrial
Threats [top]
Major Threat(s):
This species was lost as its habitat was destroyed by surface mining.
Conservation Actions [top]
Conservation Actions: This species was not protected by any national legislation. It is now believed to be Extinct.
