Scientific Name | Notobubon striatum (Thunb.) Magee |
Higher Classification | Dicotyledons |
Family | APIACEAE |
Synonyms | Annesorhiza striata (Thunb.) Koso-Pol., Dregea collina Eckl. & Zeyh., Ifdregea collina (Eckl. & Zeyh.) Steud., Peucedanum collinum (Eckl. & Zeyh.) D.Dietr., Peucedanum striatum (Thunb.) Sond., Seseli striatum Thunb. |
National Status |
Status and Criteria | Near Threatened A2bc; B1ab(iii,v) |
Assessment Date | 2012/03/02 |
Assessor(s) | D. Raimondo, I. Ebrahim & P.J.D. Winter |
Justification | A range-restricted (EOO 3468 km²) species that is estimated to have already declined by at least 25% due to habitat loss to wheat cultivation in the past 80 years (generation length 30 years). Subpopulations continue to decline due to overgrazing and competition from alien invasive plants, and around 20 locations are estimated to remain. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Breede River Valley between Bredasdorp and Albertinia. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Eastern Ruens Shale Renosterveld, Central Ruens Shale Renosterveld, Western Ruens Shale Renosterveld, Ruens Silcrete Renosterveld, Potberg Ferricrete Fynbos, Swellendam Silcrete Fynbos, Cape Lowland Alluvial Vegetation |
Description | Shale slopes confined to renosterveld and associated with silcrete outcrops. |
Threats |
| Habitat loss to wheat cultivation is estimated to have caused at least a 25% reduction in population size within the past 80 years, as well as fragmentation of this species' habitat. Fragments are typically overstocked and plants continue to decline due to heavy grazing. Ostriches have also recently been introduced to the lower Breede River Valley, and when kept in high numbers, are particularly destructive to natural vegetation. In addition, alien invasive plants are present at a number of locations. |
