Synonym/s:

Rana grafi Crochet, Dubois, Ohler and Tunner, 1995

Justification:
Listed as Near Threatened due to an observed decline as a result of competition from the introduced species P. ridibundus. The rate of decline is probably close to 30% over the last 10 years making it close to qualifying for Vulnerable.

History:

2006	–	Near Threatened (IUCN 2006)
2006	–	Near Threatened
2004	–	Least Concern

Geographic Range [top]

Range Description:	This species is present in southern France and north-eastern Spain (Catalonia, Aragon, Navarra and the Basque Country) (Crochet et al. 1995; Dubois and Ohler 1994). It is also present in the southern Rhone Valley (Pagano, Joly and Hotz 1997). It is difficult to determine the distribution limits of this species because of hybridization.
Countries:	Native: France; Spain

Population [top]

Population:	The species' population has been greatly affected by the introduction of P. ridibundus, and in many areas where it was previously found only the invasive species remains.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Rana grafi occurs in mixed colonies with R. perezi, and lives in similar habitat, being found in a wide variety of temporary and permanent waterbodies (such as pools, streams, ditches, and irrigation canals), where it breeds. Terrestrial habitats include forests, scrubland, agricultural areas and coastal marshes.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The major threat to this species is displacement by the invasive species P. ridibundus. It is possibly also threatened by the drainage of suitable wetlands for agricultural, urban and tourism development. Agrochemical pollution of breeding waterbodies is also presumed to be a threat.

Conservation Actions [top]

Conservation Actions:	This species occurs in a number of protected areas, and is listed on Appendix III of the Bern Convention. Monitoring of the population is necessary to determine the degree of decline as a result of invasive species.
