Status and Criteria | Near Threatened D2 |

Justification | This species range is very wide in Africa, South and Central America, but in South Africa the subpopulations are found in areas that are highly transformed by crop fields and afforestation. It is isolated from other subpopulations by >1000 km and the national assessment is therefore not adjusted following IUCN regional assessment guidelines. The remaining habitat is likely to be threatened by alien invasive species and prolonged periods of droughts. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Eastern Cape, KwaZulu-Natal |
Range | This species is found between Mzimvubu River in the Eastern Cape and St Lucia, north-eastern KwaZulu-Natal. |
Habitat and Ecology |
Major system | Freshwater |
Major habitats | Grassland, Indian Ocean Coastal Belt |
Description | Utricularia benjaminiana is mostly found suspended in deep to shallow, fresh or brackish water, in marshes, drying ponds, and rivers. Altitude 5-950 m. |
Threats |
| Areas surrounding the subpopulations have been extensively converted to timber plantations and crop fields. Only small remnants of suitable habitat is available, and is highly likely to be threatened by alien invasive species and droughts. |
Population |
It easily overlooked and under recorded, and known from only a few collections in South Africa. The number and size of subpopulations are however not known, and further surveys are needed to determine the status and trends of the population.
