Higher Classification | Monocotyledons |
Family | HYPOXIDACEAE |
Synonyms | Empodium occidentale (Nel) B.L.Burtt, Forbesia occidentalis Nel, Saniella occidentalis (Nel) B.L.Burtt |
Common Names | Cape Waterstar (e) |
National Status |
Status and Criteria | Near Threatened B1ab(i,ii,iii,iv,v) |
Assessment Date | 2016/08/29 |
Assessor(s) | D.A. Snijman, N.A. Helme & L. von Staden |
Justification | EOO 14 824 km², known from 10 to 15 locations and declining due to ongoing habitat loss to agricultural expansion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Hantamsberg near Calvinia southwards across the Roggeveld Escarpment to the Swartruggens Mountains and Koue Bokkeveld near Ceres. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Ceres Shale Renosterveld, Roggeveld Shale Renosterveld, Hantam Plateau Dolerite Renosterveld, Kouebokkeveld Shale Fynbos, Northern Inland Shale Band Vegetation |
Description | Seasonally inundated depressions on shale and dolerite, and shale bands in the Cederberg. |
Threats |
| This species is declining due to ongoing habitat loss to agricultural expansion around Ceres and in the Koue Bokkeveld, where many subpopulations known through historical records are now locally extinct. Two subpopulations were recently found during Environmental Impact Assessments for expansion of orchards and dam construction. On the Roggeveld Escarpment, there is some sporadic expansion of crop fields, but this threat is less severe. |
