Red List Category & Criteria: Endangered B2ab(i,iii) (Regional assessment) ver 3.1
Year Published: 2010

In northern Africa, Aeshna cyanea is severely fragmented and currently is known only from two locations in Algeria. Its extent of occurrence is less than 20,000 km² and area of occupancy is less than 500 km². Habitat loss through the fire is ongoing. A declining population trend is inferred from declining habitat size and quality.

Geographic Range [top]

Range Description:Aeshna cyanea is one of the commoner species of the genus in central Europe. It becomes scarcer towards the northeast (to Urals) and the southern parts of its range.

Northern African populations are genetically distinct from the European populations (based on ecology, but no genetic data to date; B. Samraoui, pers. comm.). It is highly localised in northern Africa, where it is only known from two localities in Algeria. The population is severely fragmented. The presence if the species in Morocco is uncertain and needs to be confirmed.
Countries occurrence:
Algeria; Spain (Spanish North African Territories)
Additional data:
Estimated area of occupancy (AOO) - km2:<500 km²
Number of Locations:2
Range Map:165524-20

Population [top]

Population:This species is inferred to be declining due to habitat loss. It is rare.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:Strictly a Nilotic species that is confined to high altitudes (very different from European range). It avoids the plains.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat loss, often livestock-related (as is true generally across the North African region).

Conservation Actions [top]

Conservation Actions: Habitat conservation is needed.
