Scientific Name | Protea cryophila Bolus |
Higher Classification | Dicotyledons |
Family | PROTEACEAE |
Common Names | Sneeublom (a), Sneeuprotea (a), Snow Protea (e), Snowball Protea (e) |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2019/09/27 |
Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Protea cryophila occurs in a small area of the Cederberg Mountain, and is known from four locations that are potentially threatened by too frequent fires, alien invasive plants 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 naturally isolated. Therefore it is listed as Vulnerable under criterion D. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the Cederberg Mountains, in the Western Cape Province, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cederberg Sandstone Fynbos |
Description | It grows on 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 that is slow to mature, it is potentially threatened by increasing fire frequency, as local extinctions can occur when fires repeatedly kill individuals before they reach reproductive maturity. It is also potentially threatened by alien invasive plants, currently present at very low densities. Climate change is an additional future potential threat. |
Population |
This species is locally common and naturally fragmented being restricted to high peaks. There are four known subpopulations, the largest is at Langberg/Shadow Peak where over 23 000 mature individuals occur. It is not suspected to be declining, and most of its habitat is intact and falls within a protected area.

Population trend | Stable |
Conservation |
| Protea cryophila is protected within the Cederberg Wilderness Area. |
