Status and Criteria | Least Concern |
Assessment Date | 2019/05/27 |
Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Protea canaliculata is widespread and not in danger of extinction. It is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs in the mountains of the Little Karoo, Western Cape, from the Hex River Mountains eastwards to the Great Swartberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Hex Sandstone Fynbos, South Swartberg Sandstone Fynbos, North Swartberg Sandstone Fynbos, South Langeberg Sandstone Fynbos, North Langeberg Sandstone Fynbos, Matjiesfontein Quartzite Fynbos |
Description | It occurs in rocky, exposed sandstone or quartzitic soils in montane fynbos, 700-1700 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 and rodents. |
Threats |
| At some localities, it is potentially threatened by competition from alien invasive plants and too frequent fires. As a reseeder, Protea canaliculata is potentially vulnerable to too frequent fires, as local extinctions can occur when fires repeatedly kill individuals before they reach reproductive maturity. |
Population |
It occurs in low densities as scattered plants over a wide area, but occasionally dense stands are encountered. As there are no current severe threats to this species, the population is assumed to be stable.
