National Status |
Status and Criteria | Least Concern |
Assessment Date | 2019/02/05 |
Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Serruria pedunculata has a restricted distribution range (extent of occurrence 4951 km²), it is however, locally common and known from more than 100 subpopulations. It is possibly declining outside the protected areas due to competition from alien invasive plants, but is not yet in danger of extinction and is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the Western Cape Province, South Africa, where it occurs from the Cederberg and Olifants River Mountains to Du Toit's Kloof, and the Riviersonderend Mountains. There is an outlying population on the Piketberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | North Hex Sandstone Fynbos, Winterhoek Sandstone Fynbos, Cederberg Sandstone Fynbos, South Sonderend Sandstone Fynbos, Hawequas Sandstone Fynbos |
Description | It grows in sandstone fynbos, 100-1500 m. Mature individuals are killed by fires, and only seeds survive. Seeds are released after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is pollinated by insects. |
Threats |
| At least 4% of this species' habitat has been lost to agriculture in the past. Most of the remaining habitat is formally protected, and there are no severe ongoing threats. There is no significant ongoing habitat loss, but some subpopulations are being impacted by alien invasive plants that are already present in many parts of the range. It is also potentially vulnerable to too frequent fires. |
Population |
This species occurs in dense, isolated subpopulations, there are over 100 subpopulation recorded. The population is suspected to be declining due to competition from alien invasive plants.
