Justification | Leucadendron arcuatum is a range-restricted species, with an extent of occurrence of 7108 km². Its habitat is mostly protected, and it has few significant threats. The population is large, and not suspected to be declining, and therefore this species is not in danger of extinction and is assessed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to a small area in the mountains of the Western Cape, from the Cederberg southwards to the Groot Winterhoek and Hex River mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | North Hex Sandstone Fynbos, Winterhoek Sandstone Fynbos, Cederberg Sandstone Fynbos, Olifants Sandstone Fynbos, Hawequas Sandstone Fynbos |
Description | It prefers stony sandstone soils in montane fynbos, 300-1900 m. It is a long-lived species, and survives fires by resprouting from underground boles or rootstocks. Seeds are released after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is dioecious, with insect-pollinated male and female flowers occurring on separate plants. |
Threats |
Most of this species' habitat is protected, and there are few significant threats to the population. A very small proportion (6%) of its habitat was lost to timber plantations in the past, but this threat has ceased as plantations are no longer expanding. Subpopulations near plantations are potentially threatened by competition from escaped pine seedlings if these are not managed. |
Population |
This species typically occurs in isolated patches of a few scattered plants, but subpopulations can be extensive, consisting of several thousand individuals.
