Justification:
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.

History:

Vulnerable

Geographic Range [top]

Range Description:	This is a coastal species occurring at low elevations (<500 m asl) along the southern coast of the Western Cape (including the Cape Peninsula), and east into the western part of the Eastern Cape. Its EOO is 18,000 km² with an estimated AOO of 5%.
Countries:	Native: South Africa (Eastern Cape Province)

Population [top]

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

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

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.
