Justification | Protea cryophila occupy a small area (AOO 68 km²), four subpopulations are potentially threatened by too frequent fire and climate change. Plants are slow to mature and therefore particularly sensitive to increased fire frequency. Although the habitat is untransformed and continuous between locations, subpopulations are isolated. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Cederberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cederberg Sandstone Fynbos |
Description | This species occurs in rocky ledges and screes, at 900-1900 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 rodents. |
Threats |
| Currently, there are no threats to this species, but as a reseeder and slow growing, it is potentially threatened by increasing high frequency of fires, as local extinctions can occur when fires repeatedly kill individuals before they reach reproductive maturity. |
Population |
This species is locally common and naturally fragmented on half a dozen high peaks. There four known subpopulations, the largest at Langberg/Shadow Peak with over 23000 mature individuals. It is not suspected to be declining, and most of its habitat is in a protected area.
