Scientific Name | Herniaria pearsonii Chaudhri |
Higher Classification | Dicotyledons |
Family | CARYOPHYLLACEAE |
National Status |
Status and Criteria | Near Threatened B1b(i,ii,iii,iv,v) |
Assessment Date | 2015/05/07 |
Assessor(s) | N.A. Helme, D. van der Colff & L. von Staden |
Justification | A range-restricted species (EOO 470 km²), that is declining in the southern parts of its range due to ongoing habitat loss to agricultural expansion, but it is estimated that more than 10 locations still remain. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Koue Bokkeveld to Swartruggens. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | North Hex Sandstone Fynbos, Cederberg Sandstone Fynbos, Swartruggens Quartzite Fynbos, Matjiesfontein Shale Fynbos |
Description | Sandy plateaus. |
Threats |
| Ongoing, sporadic agricultural expansion is causing habitat loss in the southern part of this species' range. At least one subpopulation is likely to be lost to orchard expansion in the near future (N.A. Helme, pers. obs. 2014). Further north, it occurs in Swartruggens Quartzite Fynbos, which is still 90% intact, and there is little to no ongoing threat. |
Population |
This species is known from only a few, scattered collections, but is highly likely to be overlooked, as the area where it occurs remains botanically still poorly explored, and it is cryptic and easily overlooked. More field surveys are needed to more accurately determine the size and extent of the population, but due to the large extent of this species' habitat still remaining intact, particularly in the northern parts of its range, it is estimated that there are more than 10 locations.
