Regional Assessments:
Common Name(s):
English Bladetail

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2012-02-27
Assessor(s): Boudot, J.-P., Schneider, W. & Samraoui, B.

Facilitator/Compiler(s): Alomari, K.
Justification:
The species is well adapted to desert and semi-desert environments which prevail in the core of its range (from Central Asia to Arabia). However, disjunct populations in the Mediterranean Region and northern Africa deserve a particular attention and the protection of all reproducing localities. The expected fluctuations in AOO, EOO, locations and population size is believed to be a natural situation which is linked to climate oscillations to ephemeral wetlands and water bodies. The number of new holomediterranean records is recently increasing steadily (e.g. Gastarov and Beshkow 2010). The species is therefore assessed as Least Concern.

Geographic Range [top]

Range Description:Lindenia tetraphylla is an Irano-Turanian species, distributed from Central Asia to Afghanistan and western Pakistan to the western Mediterranean (eastern Spain). It was recently also found in Bulgaria (Gastarov and Beshkov 2010). Its main range spreads over the eremian region going from Central Asia to Arabia. This is a very mobile species, nomadic, sometime found among swarms of Aeshnids Selysiothemis nigra, and Orthetrum trinacria in migration in the Middle East and Arabia (Fraser 1936, Schneider 1981). Adults are known to migrate over long distances from their reproductive locality. Many records may be ascribed to vagrant imagoes, but some isolated localities were proved to be inhabited for several consecutive years, demonstrating at least a temporary reproduction far from the core of the species' range. In particular the species has been recorded twice in the Maghreb, and although the Algerian population (dated 1849) has now disappeared, the Tunisian population was discovered more recently (2000, 2002). Similarly, the species is resident in Sardinia, in mainland Italy, the western Balkans and the south of Anatolia.

Population [top]

Population:The species is widely (thought scattered) distributed from Central Asia to Arabia and the Mediterranean with stable but disjunct populations in the Balkans, mainland Italy and Sardinia. In northern Africa, one small population was observed in 2000 (05/07/2000, 2 males) (Kunz and Kunz 2001) and 2002 (25/06/2002, 13/07/2002, one male each) (J.-P. Boudot pers.obs. ) and was during that period considered as a small reproducing population. As there is no continuous monitoring, its present status is unknown.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:No
Population severely fragmented:No
Continuing decline in subpopulations:No
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:This species reproduces in lakes and in slow-flowing rivers, e.g. upstream of river mouth in lakes. The larva are tolerant to brackish waters (Schneider 1988) and the imagoes are nomadic and migrant, and thus are well adapted to colonize ephemeral/episodical wetlands in desert and semi-desert areas during and after rainfall. The length of the larval period and their tolerance to desiccation is unknown.
Systems:Terrestrial; Freshwater
Movement patterns:Nomadic

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): Water pollution, over-irrigation and water management for human consumption with desiccation of slow flowing and stagnant water bodies affect this species, although these are not considered to have a significant effect on its population at the global level.

Conservation Actions [top]

Conservation Actions: Monitoring of good quality water bodies and rivers, including both chemical and structural aspects, is recommended.
