Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Protea caespitosa has a restricted range, with an extent of occurrence (EOO) of <1613 km², and partially fragmented population occupying a small area (AOO 51 km²). Fire-related population fluctuations occur in small, isolated subpopulations. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Protea caespitosa occurs from the Slanghoek and Du Toit's Mountains to the Kogelberg and western Riviersonderend Mountains in the Western Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Coastal Shale Band Vegetation |
Description | This species occurs in high altitude shale bands, at 1000-1800 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 |
| There are no severe threats to this species, but it is potentially vulnerable to too frequent fire, as well as aseasonal fires. |
Population |
Population trend | Fluctuating |
