Schwantesia constanceae
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Schwantesia constanceae faces severe pressure from habitat degradation in its restricted range within the Succulent Karoo biome of South Africa. Agricultural expansion and overgrazing by livestock have fragmented its specialized quartz field habitats, while climate change threatens to alter the precise moisture and temperature conditions this succulent requires. Mining activities and urban development further reduce available habitat, with the species' slow growth rate limiting its ability to recover from disturbances.
Habitat
This species is endemic to the quartz fields and rocky outcrops of the Succulent Karoo in the Northern Cape Province of South Africa. It grows in specialized microhabitats among quartz pebbles and granite formations, requiring well-drained soils and specific moisture conditions typical of winter-rainfall Mediterranean-type ecosystems.
