Stellenbosch University Botanical Garden, South Africa

Common name: Stacked crassula

Family: Crassulaceae (Sedum)

Synonym: Crassula pseudocolumnaris

Distribution: Namibia, Northern Cape

IUCN Red list: Not evaluated

National red list: Vulnerable

Life form: Succulent plant

Comments: Threatened by ongoing habitat loss and degradation as a result of open-cast mining across its range in South Africa and Namibia. In places such as around the Buchuberg, degradation extends far beyond the mining sites due to windblown dust from mining disturbance and exposed mine dumps covering large areas, burying this species' quartz gravel habitat in sand. East of Alexander Bay it is also threatened by trampling and degradation due to severe overstocking of livestock.
