Scientific Name: Trapelus savignii
Species Authority: (Duméril & Bibron. 1837)
Common Name(s):
English Savigny's Agama
Synonym(s):
Agama savignii Duméril & Bibron, 1837

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2abcd ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Werner, Y. & El Din, S.B.
Reviewer(s): Stuart, S.N. & Cox, N. (Global Reptile Assessment)
Justification:
Listed as Vulnerable because of a population decline, estimated to be more than 30% over the last three generations, inferred from over-exploitation, shrinkage in distribution, and habitat destruction and degradation.

Geographic Range [top]

Range Description:This species is restricted to the western Negev sands of Israel and the Gaza Strip, extending westwards across north Sinai to the eastern margins of the Nile Delta. Populations between the Suez Canal and the Nile Delta are highly fragmented and have almost been extirpated, with an estimate of 80% habitat loss in this region. Populations south of Tel Aviv in Israel are believed to be extinct. It is a lowland species possibly occurring up to 200 m asl.
Countries occurrence:
Native:
Egypt; Israel; Palestinian Territory, Occupied

Population [top]

Population:It is moderately common in Israel, but its range is diminishing due to habitat loss. This species was reported to be numerous in Egypt by Flower (1933), it has since declined overall, but it is still locally common in some localities in Sinai (S. Baha El Din pers. comm.)
Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:It is found in sandy and gravel desert and desert edge habitats, often in small, stabilised valleys between dunes. It can be encountered in open steppe-like areas with a good vegetation cover. It is not present in rocky or stony terrain and is generally not present in cultivated land. It is an egg-laying species.
Systems:Terrestrial

Threats [top]

Major Threat(s): The threats to this species include a general loss of habitat due to human settlement, overgrazing, large-scale agricultural expansion, land reclamation, quarrying, solid waste dumping and off-road vehicles. The species is also collected for the international pet trade.

Conservation Actions [top]

Conservation Actions: In Israel it occurs in a few reserves, including Nizzana Sands. In Egypt it is present in the Zaranik protected area. There is a need to develop national legislation to protect this species in Egypt, and possibly it should be protected by international legislation. Protected areas should be established at important localities for the species. Awareness raising and community conservation measures are needed for the conservation of this species.
