National Status |
Status and Criteria | Vulnerable B1ab(i,ii,iii,iv) |
Assessment Date | 2018/10/04 |
Assessor(s) | R.C. Turner, N.A. Helme & L. von Staden |
Justification | Erica pilosiflora subsp. pilosiflora has a restricted range, with an extent of occurrence (EOO) of 464 km², and an area of occupancy (AOO) of 36-44 km². It remains at fewer than 10 locations after more than 30% habitat loss. It continues to decline due to ongoing habitat loss and degradation, as well as competition from alien invasive plants. It is therefore listed as Vulnerable under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This subspecies is endemic to the Western Cape, South Africa, where it is found from Sir Lowry's Pass to Villiersdorp and Hawston. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Ruens Silcrete Renosterveld, South Sonderend Sandstone Fynbos, Overberg Sandstone Fynbos, Kogelberg Sandstone Fynbos |
Description | It occurs on low altitude quartzite slopes in fynbos. |
Threats |
| About 33% of this subspecies' habitat has been lost to fruit orchards and timber plantations, as well as housing estates on Sir Lowry's Pass. Remaining subpopulations are predominantly threatened by spreading, unmanaged alien invasive plants, particularly around Houw Hoek. |
Population |
The population size is of this subspecies is not known, but notes on herbarium specimens suggest that subpopulations are small. A continuing decline is inferred from ongoing habitat loss and degradation.
