Reptiles of Sardinia: updating the knowledge on their distribution

Sardinia shows a clear lack of herpetological data due to an evident paucity of herpetological surveys. This gap of knowledge is worthy of attention, since Sardinia hosts a rich herpetofauna with a large proportion of endemic species, and distribution data are crucial for targeting conservation efforts. In this paper we provide new distribution data for Sardinian reptiles, with the aim of updating our knowledge on their specific distribution. Data were opportunistically recorded during ten years of field research in Sardinia, carried out in more than twenty campaigns from April 1999 to June 2009. All the eighteen reptile species belonging to the Sardinian fauna were recorded. A total amount of 293 faunistic data were collected from 178 different localities covering the entire study area. Within this dataset, 137 faunistic data fall outside known species’ ranges as reported in the Atlas of Italian amphibians and reptiles. In conclusion, data presented here produced a remarkable increase of knowledge on Sardinian reptiles distribution compare to that reported in the last available syntheses. Nevertheless, it should be evidenced that, notwithstanding the present updating, the knowledge of Sardinian reptiles’ distribution is probably still far from being exhaustive. Thus, further investigations are strongly required for obtaining a complete picture and identifying conservation priorities in terms of isolated species/populations and areas of high diversity and endemicity.
