État de la populationExpert
Population decline has taken place since ± 1940 and more than 80% of this species' habitat is now lost. The generation length for bulbinellas is unknown, but is unlikely to exceed 20 years, so an A2 listing is not possible. Individual plants are very sensitive to disturbance and trampling and grazing will cause individuals to die. The size of subpopulations has not been sufficiently quantified to determine if this taxon  qualifies as severely fragmented.

Description complète des menacesExpert
This taxon is currently threatened by livestock overgrazing, individuals are sensitive to grazing. Habitat loss to wheat and pasture crop cultivation is a past threat on the Bokkeveld Escarpment with over 80% of this taxon's habitat was lost to ploughing since 1940. Future ploughing and changes in climate are potential threats.
