| Scientific Name | Cotula eckloniana (DC.) Levyns | Higher Classification | Dicotyledons | Family | ASTERACEAE | Synonyms | Cotula pedunculata (Schltr.) E.Phillips, Otochlamys eckloniana DC., Otochlamys pedunculata Schltr. |
National Status | Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) | Assessment Date | 2013/09/16 | Assessor(s) | R.F. Powell, N.A. Helme, D. Raimondo & L. von Staden | Justification | EOO 8587 - 18 685 km², AOO <100 km², a rare species that has lost more than 50% of its habitat to urban and agricultural expansion. Seven locations are confirmed to remain, and are scattered over a wide area, but up to 15 locations possibly still remain in areas where this species has been recorded in the past, but no recent surveys for this species have yet been done. There is however ongoing, rapid agricultural expansion within these areas, and therefore a higher status of Vulnerable is maintained. |
Distribution | Endemism | South African endemic | Provincial distribution | Western Cape | Range | Lambert's Bay southwards along the Cape West Coast to the Cape Peninsula and Agulhas Plain. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Overberg Dune Strandveld, Cape Flats Dune Strandveld, Langebaan Dune Strandveld, Saldanha Flats Strandveld, Agulhas Sand Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos, Leipoldtville Sand Fynbos | Description | Saline alluvium floodplains, salt pans and sandy coastal flats. |
Threats | | Lowland coastal vegetation within this species' known range is already more than 50% irreversibly modified, predominantly for crop cultivation and urban expansion. It is suspected to be locally extinct on the Cape Peninsula, although a subpopulation may still remain within the Silvermine section of the Table Mountain National Park, where it was last recorded more than 100 years ago. A few isolated subpopulations have been recently recorded along river floodplains on the West Coast and Agulhas Plain, and coastal salt pans amidst crop fields on the Vredenburg Peninsula. A few other subpopulations, known from historical records from the Sandveld areas around Hopefield could possibly still be relocated, but are all threatened by extensive ongoing habitat loss to expanding potato and rooibos tea cultivation. |
