Scientific Name | Silene crassifolia L. subsp. crassifolia |
Higher Classification | Dicotyledons |
Family | CARYOPHYLLACEAE |
National Status |
Status and Criteria | Least Concern |
Assessment Date | 2014/05/09 |
Assessor(s) | L. von Staden |
Justification | A range-restricted subspecies (EOO 19 745 km²) that is declining across its range due to habitat loss and degradation. It is however still common, occurring at more than 30 locations, and is not yet in danger of extinction, but needs to be monitored. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Western Cape coast from Saldanha to Struisbaai. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Deep sandy soils just above the high-tide water level, and stabilized or partially stabilized coastal dunes. |
Threats |
| This subspecies is threatened by habitat loss and degradation due to coastal development and urban expansion across its range. Around False Bay and Cape Agulhas it is also threatened by competition from unmanaged alien invasive plants. In spite of these threats, it is however still common, and survives even in heavily impacted dune systems such as at Fish Hoek Beach on the Cape Peninsula. |
Population |
This subspecies is localized to coastal dunes a few metres from the sea, but is locally abundant within this habitat.

Population trend | Decreasing |
