Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Leucadendron uliginosum subsp. uliginosum has a restricted range, with an extent of occurrence (EOO) of 2879 km². It is abundant within its habitat, occurring at more than 50 locations. Alien invasive plants, particularly escaped pine seedlings, continue to spread into its habitat, however the population has not yet declined significantly. This taxon is not in danger of extinction. It is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This subspecies is endemic to South Africa, and is found in the Outeniqua Mountains between Cloete's Pass and Plettenberg Bay. An isolated subpopulation occurs in the Langeberg above Swellendam. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Tsitsikamma Sandstone Fynbos, South Outeniqua Sandstone Fynbos, North Outeniqua Sandstone Fynbos, South Langeberg Sandstone Fynbos, North Langeberg Sandstone Fynbos |
Description | It occurs on stony sandstone slopes in montane fynbos, 400-1500 m. Mature individuals are killed by fires, and only seeds survive. Seeds are stored in fire-resistant inflorescences, and released after fires. It is dioecious, with insect-pollinated male and female flowers occurring on separate plants. |
Population |
It is abundant, occurring in large, extensive subpopulations. It often dominates its habitat in the Outeniqua Mountains. A continuing decline is inferred from competition from alien invasive plants that continue to spread and increase in density within its habitat.
