Geographic Range [top]

Range Description:	This species was recorded from only two localities on the eastern shore of Lake Huleh, Israel. It seems possible that it could once also be found in adjacent parts of Syrian Arab Republic. The map indicates the possible former range.
Countries:	Regionally extinct: Israel

Population [top]

Population:	It is known only from a few specimens and is now believed to be extinct. The single adult collected in 1955 represents the last confirmed record of this species.

Habitat and Ecology [top]

Habitat and Ecology:	The species was reported to occur in marginal freshwater habitats within the Lake Huleh wetlands of Israel. It was presumably a larval developing species.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The Huleh marshes were drained in the 1950s in an attempt to both eradicate malaria and to make the land suitable for agricultural use. Of the original 6,000ha of marshland, only 300ha remained after drainage. While this remaining wetland was set aside as a nature reserve in 1964 (at a considerable distance from the recorded localities of Discoglossus nigriventer) it seems that this action was too late to save the species.

Conservation Actions [top]

Conservation Actions:	The species remains protected by national legislation in Israel. Surveys of potentially suitable habitat in the Aammiq marsh of nearby south-east Lebanon in April 2004 and April 2005 failed to locate any animals (Tron 2005). The Aammiq marsh is the only remaining wetland fragment of the Bekaa valley, which was once a major wetland of the Middle East but has been drastically reduced by conversion to agricultural use and urban development.
