Scientific Name | Aponogeton fugax J.C.Manning & Goldblatt |
Higher Classification | Monocotyledons |
Family | APONOGETONACEAE |
National Status |
Status and Criteria | Endangered B2ab(iii) |
Assessment Date | 2010/09/02 |
Assessor(s) | D. Raimondo & J.C. Manning |
Justification | A wetland habitat specialist that has an AOO of less than 20 km². Subpopulations are severely fragmented and it is experiencing an ongoing decline in habitat quality due to invasive alien plant invasions, and changes in hydrological processes associated with conversion of surround matrix habitat to agriculture and urban development. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Bokkeveld Escarpment to Agulhas Plain. |
Habitat and Ecology |
Major system | Freshwater |
Major habitats | Swartland Shale Renosterveld, Swartland Granite Renosterveld, Bokkeveld Sandstone Fynbos, Elim Ferricrete Fynbos |
Description | Silt or clay in shallow waters in vernal pools, or in seasonal or permanent water bodies. |
Threats |
Habitat has been lost to ploughing for rooibos tea on the Bokkeveld Escarpment. The Agulhas Plain subpopulations are threatened by habitat degradation due to alien plant infestations. The habitat of the subpopulation from Darling is threatened by changes in surrounding land use (agricultural areas have become urbanised). This will likely change hydrology from a seasonal pan to a permanent water body. Pollution in the form of agricultural and urban runoff is also degrading the habitat of this species. |
Population |
Population trend | Decreasing |
Notes |
The delicate, short-lived flowers and submerged leaves raise the possibility that careful examination of other vernal pools along the West Coast, such as those around Hopefield, may reveal additional subpopulations. |
