Scientific Name | Ixia pumilio Goldblatt & Snijman |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Endangered B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2012/11/01 |
Assessor(s) | P. Goldblatt, J.C. Manning & L. von Staden |
Justification | Plants at two known locations (EOO and AOO <10 km²) continue to decline due to habitat degradation, competition from alien invasive plants and expanding vineyards. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Breede River Valley south of Worcester. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Breede Alluvium Fynbos |
Description | Deep alluvial sands on riverbanks. |
Threats |
The two known localities for this species, on adjacent farms on the banks of the Breede River, are both small fragments surrounded by vineyards, and one is severely degraded and overrun with alien invasive plants. It occurs on privately owned land where it is threatened by ongoing agricultural expansion. |
Population |
This species was first discovered in 1983, and to date remains only known from a single subpopulation. Some population estimates indicated that there are less than 200 plants, however, it was also reported to be locally abundant in 1984-5. Since then, the site has been increasingly degraded. The species was recorded in the same area again in 2012, but surveys are needed to determine the extent and size of the population.
