The amphibian and reptilian fauna of Deg˘irmenbog˘azı Nature Park, Balıkesir Province, Turkey

Abstract

We surveyed the herpetofauna of Değirmenboğazı Nature Park and its surroundings, in Balıkesir Province,
Turkey, and encountered a total of 3,229 individuals of four amphibian (three anurans, one salamander) and 21 reptilian
species (three turtles, 12 snakes, six lizards), plus an additional invasive species of turtle. Most observations were
recorded during the spring, while the fewest were observed in August and September. The most frequently observed
species were Pelophylax cf. bedriagae (Anatolian Waterfrog), Laudakia stellio (Roughtailed Rock Agama), Lacerta diplochondrodes
(Rhodos Green Lizard), Eirenis modestus (Asia Minor Dwarf Racer), and Montivipera xanthina (Ottoman
Viper). The least observed species were Platyceps collaris (Red-headed Sand Racer) and Malpolon insignitus (Eastern
Montpellier Snake). Our results indicate that the study area supports 17.4% of the country’s and 62.5% of the province’s
herpetofauna. Species richness was primarily concentrated in the scrub and rocky areas in the northern part of
the study area, in contrast to the coniferous forests in the southern part. We anticipate that these data will inform the
development of improved regional conservation strategies.
