Scientific Name | Wurmbea compacta B.Nord. |
Higher Classification | Monocotyledons |
Family | COLCHICACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2015/11/17 |
Assessor(s) | L. von Staden |
Justification | EOO 521 km², plants at fewer than 10 known locations continue to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Montagu to Barrydale. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Little Karoo, Montagu Shale Renosterveld, Montagu Shale Fynbos |
Description | Montagu Shale Renosterveld, in damp soils derived from shales. |
Threats |
| This species has lost extensive habitat to agricultural expansion in the valleys along the northern side of the Langeberg between Montagu and Barrydale, and habitat loss predominantly to expanding vineyards continues. In addition, more than 50% of uncultivated renosterveld in the area is severely overgrazed (J.H. Vlok pers. obs.). Additional threats include habitat loss to quarrying and competition from alien invasive plants. |
