Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | Leucadendron loeriense has a restricted distribution range (Extent of Occurrence 7343 km²), and is known from only a few, isolated subpopulations. Subpopulations are however large, and there is no significant ongoing population decline, and therefore it is not in danger of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, Western Cape |
Range | This species is endemic to a small area in the mountains of the Eastern Cape between Port Elizabeth and the Western Cape border. It has been recorded in the Witteberg, Baviaanskloof, Kouga, Groot Winterhoek and Elandsberg mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kouga Grassy Sandstone Fynbos, Kouga Sandstone Fynbos, Grootrivier Quartzite Fynbos |
Description | It occurs in montane sandstone fynbos, 450-1700 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 dioecious, with insect-pollinated male and female flowers occurring on separate plants. |
Threats |
| Subpopulations in the area surrounding the type locality were lost to timber plantations. The plantations are however no longer expanding, and are being phased out, and therefore this threat has largely ceased. Subpopulations in the eastern end of this species' range are threatened by too frequent fire, and field surveys are needed to confirm whether they still persist. It is threatened by competition from alien invasive plants in the Elandsberge, but Protea Atlas Project surveys recorded 74% of localities to be free of alien plants. |
Population |
Subpopulations of this species are large and isolated. It was previously thought to be rare, but during Protea Atlas Project surveys, 34 subpopulations were recorded over a 160 km range. It has declined in the past, but there is no current significant ongoing decline.
