Scientific Name | Dierama luteoalbidum I.Verd. |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii) |
Assessment Date | 2007/05/17 |
Assessor(s) | I.M. Johnson, C.R. Scott-Shaw, D. Raimondo & L. von Staden |
Justification | Known from a very small range (EOO 1200-5500 km²), and eight to 10 locations in an area that is highly transformed by forestry plantations and where heavy grazing by livestock is causing a continuing decline in habitat quality. |
Distribution |
Endemism | South African endemic |
Provincial distribution | KwaZulu-Natal |
Range | KwaZulu-Natal Midlands. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Midlands Mistbelt Grassland, Mooi River Highland Grassland |
Description | Open grassland in deep, dolerite soils, 1100-1700 m. |
Threats |
| Much of the habitat of this species is either undergoing afforestation or is heavily grazed (Hilliard & Burtt 1991). Grassland transformation by agriculture and forestry has severely reduced suitable habitat. Less than 1% of the grasslands of Moist Midlands Mistbelts remain and less than 0.3% is protected. Midlands Mistbelt Grassland is one of the most threatened vegetation types of KwaZulu-Natal (Mucina & Rutherford 2006). |
