Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2012-04-29
Assessor(s): Boudot, J.-P., Dijkstra, K.-D.B., Clausnitzer, V., Suhling, F., Schneider, W. & Samraoui, B.
Reviewer(s): García, N., Tognelli, M. & Suhling, F.
Facilitator/Compiler(s): Alomari, K.
Justification:
Anax speratus is a widespread African species with no known major widespread threats, although destruction of spring habitats (brooks, ponds) in some part of its range may affect the species in the future (Martens et al. 2010, Schneider, pers. obs.), but it is unlikely to be declining fast enough to qualify for listing in a threatened category. It is therefore assessed as Least Concern.
History:
2006 Least Concern

Sometimes recorded on pools created by springs.
Systems: Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): Habitat loss and degradation due to groundwater extraction and water pollution are threats to the species, however, these are not considered to be significantly affecting the global population at present.

Conservation Actions [top]

Conservation Actions: No conservation measures are known to be in place or needed for this species but research on population ecology, habitat status and population trends would be valuable.
