Scientific Name | Lampranthus explanatus (L.Bolus) N.E.Br. |
Higher Classification | Dicotyledons |
Family | AIZOACEAE |
Synonyms | Mesembryanthemum explanatum L.Bolus |
National Status |
Status and Criteria | Near Threatened A4c; B1ab(i,ii,iii,iv,v) |
Assessment Date | 2012/12/19 |
Assessor(s) | C. Klak, N.A. Helme, D. Raimondo & L. von Staden |
Justification | A widespread (EOO 19 472 km²), and formerly abundant species that has declined extensively due to over 50% habitat loss to urban expansion, crop cultivation, coastal development and competition from alien invasive plants. A population reduction of at least 10% is estimated to have occurred in the past 15 years (one generation) and is estimated to reach 20-25% within the next 30 years (two generations), based on current rates of habitat loss. Between 25 and 35 locations still remain. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Redelinghuys to the Cape Peninsula and the Agulhas Plain. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Dune Strandveld, Cape Flats Dune Strandveld, Langebaan Dune Strandveld, Swartland Granite Renosterveld, Peninsula Sandstone Fynbos, Agulhas Limestone Fynbos, Boland Granite Fynbos, Agulhas Sand Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos, Leipoldtville Sand Fynbos |
Description | Lowland sand fynbos. |
Threats |
| This species lowland fynbos habitat is already 50% transformed, and loss continues. In the Sandveld, rapid, recent expansion of potato and rooibos tea cultivation has led to extensive loss in the past 10-15 years. On the Cape Flats and Cape Peninsula, many subpopulations known from historical records are now locally extinct due to habitat loss to urban expansion, and loss is continuing. On the sandy flats around Malmesbury, Mamre and Atlantis, plants are predominantly threatened by competition from dense infestations of alien invasive wattles, while urban and industrial expansion is also causing continued habitat loss. On the coast between Gansbaai and Struisbaai, coastal development is also causing ongoing habitat loss. |
Population |
A widespread, and formerly abundant species of the Cape's coastal lowlands. It is still fairly common, with around 20 locations that have been recently recorded. This species' habitat is already 50% transformed, and based on calculations of changes in landcover, it is estimated that around 10% of this loss occurred in the past 15 years (one generation). Based on these rates of habitat loss, it is estimated that a population reduction of 20-25% will be reached within the next 30 years (two generations).
