Scientific Name | Metalasia alfredii Pillans |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2019/04/04 |
Assessor(s) | N.A. Helme & L. von Staden |
Justification | A rare, range-restricted species known from two locations and potentially threatened by competition from alien invasive plants. It therefore qualifies as Vulnerable under criterion D. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs in the Riviersonderend Mountains, Pilaarkop and Baviaanskloof above Genadendal. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Sonderend Sandstone Fynbos, Hawequas Sandstone Fynbos |
Description | Plants grow on upper sandstone slopes and summit ridges above 1500 m. |
Threats |
| Alien invasive pines have been spreading rapidly across the southern slopes of the Riviersonderend Mountains over the past 15 years. At present scattered pines have reached the summit ridges and north-facing slopes, and require urgent clearing. If left unmanaged, pines will outcompete native species. |
