Description | Granite fynbos. |
Threats |
| Ixia aurea occurs in one of the most highly transformed areas of the Western Cape (EOO >80% transformed), and its habitat has been fragmented by crop cultivation. A few isolated subpopulations remain, and these are threatened by ongoing habitat loss and degradation due to still expanding crop cultivation, spreading of alien invasive plants - especially alien grasses due to fertilizer runoff from surrounding crop fields, overgrazing and fire exclusion. |
Population |
An extremely rare species, known from very few collections (Goldblatt and Manning 2011). The population is fragmented, and currently known from only three isolated subpopulations. The species may however also be overlooked, as it is very similar to two other common yellow-flowered species, I. maculata and I. dubia (Goldblatt and Manning 2011).
