Scientific Name | Treichelia dodii Cupido |
Higher Classification | Dicotyledons |
Family | CAMPANULACEAE |
National Status |
Status and Criteria | Endangered B2ab(iii) |
Assessment Date | 2012/12/21 |
Assessor(s) | L. von Staden |
Justification | EOO 7365 km², AOO estimated <500 km², small, isolated and severely fragmented subpopulations continue to decline due to ongoing habitat loss and degradation as a result of urban and agricultural expansion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Malmesbury to the Cape Peninsula and Riversdale. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Granite Renosterveld, Peninsula Granite Fynbos, Swellendam Silcrete Fynbos |
Description | Loamy granite derived soils on flats and lower slopes. |
Threats |
| Part of the subpopulation at Malmesbury was lost to a housing development, and remaining plants are threatened by further proposed developments. The subpopulation on the Cape Peninsula is protected within Table Mountain National Park and is not threatened. The subpopulation at Riversdale is very likely extinct due to habitat loss to agricultural expansion. Elsewhere, suitable granite renosterveld habitat has been extensively transformed due to agricultural and urban expansion, and less than 30% remains. |
Population |
An apparently very rare, but also poorly known species, with an unusually disjunct distribution. Two recently surveyed subpopulations both consist of fewer than 50 mature individuals, while the third subpopulation was recorded more than 75 years ago, but not recollected again (Cupido 2011). Very little granitic fynbos and renosterveld remains, and thorough surveys of fragments between Malmesbury and the Cape Peninsula by volunteers of the Custodians of Rare and Endangered Wildflowers have not recorded this species anywhere else in this area. It is possible that this species may be overlooked in similar suitable habitat, but these are likely to all be small and isolated within remnant patches of natural vegetation.
