Scientific Name | Lampranthus spiniformis (Haw.) N.E.Br. |
Higher Classification | Dicotyledons |
Family | AIZOACEAE |
Synonyms | Lampranthus inconspicuus (Haw.) Schwantes, Mesembryanthemum inconspicuum Haw., Mesembryanthemum spiniforme Haw. |
Common Names | Renoster Brightfig (e) |
National Status |
Status and Criteria | Vulnerable B1ab(iii) |
Assessment Date | 2018/10/03 |
Assessor(s) | L. von Staden & C. Klak |
Justification | Lampranthus spiniformis has an extent of occurrence (EOO) of 11 794 km². It has 25-35 severely fragmented subpopulations which continue to decline due to ongoing habitat loss and degradation. It is therefore listed as Vulnerable under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, and is found from Saron to Genadendal. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Granite Renosterveld, Swartland Shale Renosterveld, Boland Granite Fynbos, Cape Winelands Shale Fynbos, Breede Shale Renosterveld, Swartland Alluvium Fynbos, Swartland Silcrete Renosterveld, Lourensford Alluvium Fynbos, Atlantis Sand Fynbos, Greyton Shale Fynbos, Peninsula Granite Fynbos, Cape Flats Sand Fynbos, Hangklip Sand Fynbos, Breede Sand Fynbos, Elim Ferricrete Fynbos, Breede Alluvium Fynbos, Breede Shale Fynbos, Elgin Shale Fynbos, Breede Quartzite Fynbos, North Sonderend Sandstone Fynbos, South Sonderend Sandstone Fynbos, Peninsula Shale Renosterveld, Peninsula Shale Fynbos |
Description | It occurs on stony lower slopes, most often on granite or ecotonal areas between sand and shale. |
Threats |
| Lampranthus spiniformis has lost more than 70% of its habitat to urban and agricultural expansion, and this habitat loss continues. Remaining habitat fragments also continue to be degraded due to dense infestations of alien invasive plants, overgrazing and inappropriate fire management. |
Population |
It is a widespread species that is still common in spite of extensive habitat loss. Recent field observations recorded it in at least 25 locations, but nearly all of these are isolated remnants with only a few plants. The population is therefore considered severely fragmented and continues to decline due to ongoing habitat loss and degradation.
