Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-02-01
Assessor(s): Suhling, F.
Reviewer(s): Kipping, J., Simaika, J.P., Samways, M.J., Suhling, F. (Odonata Red List Authority) & Pollock, C.M. (IUCN Red List Unit)
Justification:
This species is still widespread and common in South Africa and seems even to benefit from some human impacts (Samways 1999). Therefore from a global perspective it is not threatened. In Namibia, however, where the species is marginal, the remaining population is very small and may be threatened (e.g., from natural disasters). Its only known location in Namibia is within Namib-Naukluft National Park. It has not been recorded from the two other known Namibia locations for more than 80 years.
History:
2009 Least Concern
2008 Least Concern (IUCN 2009.2)
2007 Least Concern

Population [top]

Population: The species seems to be split into three subpopulations, two in South Africa (several inhabited localities) and one small subpopulation in Namibia. It is most likely extinct at two out of the three known localities, as it has not been seen there for more than 80 years.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Occurs in small mountain streams with pools. Larvae seem to live mainly in pools and in South Africa the species seems to profit from damming of small streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat degradation is the major threat to the species. In Namibia, groundwater extraction was most likely the reason why two subpopulations were lost.

Conservation Actions [top]

Conservation Actions: Policy-based actions, increasing awareness and research into biology and ecology, conservation measures and trends/monitoring of the species would all be valuable. Habitat protection is also required for this species.
