French Lezard de Derjugin
Lacerta derjugini (Nikolsky, 1898)
Taxonomic Notes: Of the six described subspecies, five are distributed in the Caucasus. D. d. sylvatica (Bartenjev and Reznikova, 1931) inhabits the submontane part of the Krasnodar Territory, mainly in the Caucasian Biosphere State Reserve and the adjacent spurs of the Great Caucasus. D. d. boehmei (Bishoff, 1982) lives in the western spurs of the Great Caucasus in Krasnodar Territory and adjoining regions of Abkhazia up to Kodor River valley in the southeast. D. d. abchasica (Bishoff, 1982) inhabits the coast of the Black Sea of Abkhazia and the adjacent regions of western Georgia, D. d. barani (Bishoff, 1982) is known from coastal mountains regions of Ajaria and of neighbouring part of north-eastern Turkey. D. d. orlowae (Bishoff, 1984) inhabits southern slopes and foothills of the Great Caucasus in Georgia and northwestern Azerbaijan.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2009
Date Assessed: 2008-12-14
Assessor(s): Tuniyev, B., Ananjeva, N.B., Agasyan, A., Orlov, N.L. & Tuniyev, S.
Reviewer(s): Cox, N.A. & Temple, H.J.
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss and fragmentation of remaining populations through much of its range, thus making the species close to qualifying for Vulnerable.

Habitat and Ecology [top]

Habitat and Ecology:This species is typically associated with damp areas in forested montane habitats; animals are occasionally recorded from rocks or walls. The subspecies D. d. silvatica populates mesophilous flood plains, beech and fir tree forests usually from 600m up to 1,300m, and occasionally up to 1,600m asl. D. d. boehmei inhabits forests and subalpine meadows from sea level (in Ajaria) to 1,800m asl (Trialetsky ridge). It is absent from sea shore xerophilous habitats. The female lays a clutch of between four and eight eggs (Baran and Atatur 1998).

Threats [top]

Major Threat(s): Ongoing habitat loss through deforestation is considered to be a major threat to this species. The montane habitats of this species are believed to be increasingly threatened by climate change.

Conservation Actions [top]

Conservation Actions: This species is found within the Caucasian State Biosphere Reserve and the Sochi State Natural National Park. There is a need to conserve suitable remaining areas of forest habitat for this species.

Errata [top]
