Justification | Protea scabriuscula has a restricted distribution range, with an extent of occurrence (EOO) of 2092 km², and an area of occurrence (AOO) of 152 km². The subpopulations are small and isolated. However, it does not yet meet any criteria for a category of threat and is listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs from Hex River Mountains and Koue Bokkeveld in the Western Cape Province, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | North Hex Sandstone Fynbos, Winterhoek Sandstone Fynbos, Cederberg Sandstone Fynbos, Western Altimontane Sandstone Fynbos, Swartruggens Quartzite Fynbos |
Description | It occurs on rocky, east-facing sandstone slopes, 1100-2100 m. Mature individuals are killed by fires, and only seeds survive. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is pollinated by birds. |
Threats |
| Protea scabriuscula is potentially threatened by alien invasive species which are already present at low densities and too frequent fires. |
Population |
This species is known from 18 small isolated subpopulations which are not declining.
