Listed as Least Concern as although it has a relatively restricted extent of occurrence (18,000 km2), its area of occupancy (900 km2) is large. It is not considered to be severely fragmented, and despite some impact on a limited number of subpopulations, it is known to adapt to disturbed environments.
Previously published Red List assessments:
2012 Least Concern (LC)
2004 Vulnerable (VU)

Population [top]


This species is relatively abundant in many wetland areas and can tolerate disturbance. It is not considered to be severely fragmented.

Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in wetlands in coastal fynbos heathland. It breeds in large and small pans, dams, vleis, and even slow-flowing streams. It needs emergent vegetation, and therefore requires relatively permanent water, though it seems to avoid very deep water.
Systems: Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat: Unknown

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): Spreading alien vegetation can lead to drying out of its breeding habitats. It is probably also adversely affected by fires. Several populations have disappeared due to the impacts of agricultural and urban expansion on its native habitat. No evidence exists that collection of Arum Lily flowers affects this species in any way whatsoever.

Conservation Actions [top]

Conservation Actions: No conservation actions are currently prioritised for this species. It occurs in several protected areas, including Table Mountain National Park and De Hoop Nature Reserve.
