Scientific Name | Babiana nana (Andrews) Spreng. subsp. nana |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
Synonyms | Babiana nana (Andrews) Spreng. var. nana |
National Status |
Status and Criteria | Endangered B2ab(ii,iii,v) |
Assessment Date | 2021/11/04 |
Assessor(s) | L. von Staden & T. Patel |
Justification | This taxon has an extent of occurrence (EOO) of 5453 km², and an area of occupancy (AOO) of 248 km². Subpopulations of this subspecies are fragmented and declining mainly due to coastal development and alien plant invasion. It almost qualifies to be listed as Vulnerable under criteria B. It is therefore listed as Near Threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is endemic to South Africa, and is found from Milnerton to Vredenburg Peninsula in the Western Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cape Flats Dune Strandveld, Langebaan Dune Strandveld, Saldanha Flats Strandveld, Saldanha Granite Strandveld, Swartland Granite Renosterveld, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos |
Description | It occurs in sand plain fynbos and dune strandveld, sandy coastal flats and dunes. |
Threats |
| This taxon has lost 41% of its habitat (calculated using landcover data in GIS). Agriculture is a past threat to most of the inland subpopulations, and in areas such as Atlantis, Milnerton and Bloubergstrand urban expansion has led to the extinction of many subpopulations last recorded in the 1940s and 1950s. At present subpopulations further north along the coast between Melkbosstrand and the Vredenburg Peninsula are severely threatened by rapidly expanding coastal development, especially on the Vredenburg Peninsula and around former small West Coast fishing villages such as Yzerfontein, Jacobsbaai and Bokbaai. Sand plain fynbos is also the vegetation type most severely affected by dense infestations of alien Acacias such as Port Jackson, and critically little undisturbed vegetation remains. |
Population |
Subpopulations of this taxon are severely threatened across its range. Citizen science records since 2005 indicate that the majority of subpopulations are small and have between 10 and 50 mature individuals present while no subpopulation monitored has more than 250 mature individuals. The population is declining due to ongoing habitat loss and degradation.

Population trend | Decreasing |
Conservation |
