Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos, Cape Winelands Shale Fynbos, Boland Granite Fynbos, Western Coastal Shale Band Vegetation |
Description | This species occurs in steep, gravelly, lower west-facing coastal slopes, at 0-400 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 |
| A reseeder potentially threatened by too frequent fire, urbanization, and alien invasive plants. Although the Kogelberg is a well-managed biosphere reserve, too frequent fires are becoming a problem. Many of the plants are entirely dependant upon endemic ants for dispersal of seeds and for fire survival. Thus. alien invasive ants are likely to be a threat as they would displace the indigenous ants. |
Population |
Leucospermum bolusii is a rare endemic that occupy a small area with a large and dense population.
