Distribution of non-native terrestrial and freshwater amphibians and reptiles in Scotland

Abstract

Surveillance of non-native species is important for biosecurity and ecological reasons. This paper presents a baseline of the distribution of non-native terrestrial and freshwater amphibian and reptile species in Scotland. Multiple datasets were used to confirm which non-native terrestrial and freshwater species of amphibians and reptiles are currently present in Scotland, and map their known distribution. Citizen Science records were found to be extremely useful when photographs were included. Four non-native terrestrial and freshwater amphibian and reptile species were found to be present in Scotland, including Alpine newt (Ichthyosaura alpestris), sand lizard (Lacerta agilis), Chinese pond turtle (Mauremys reevesii), and common slider (Trachemys scripta).
