Eaten or beaten? Severe population decline of the invasive lizard Podarcis siculus (Rafinesque-Schmaltz, 1810) after an eradication project in Athens, Greece

Abstract

Invasive species have been recognised as an important hazard to native communities. Amongst the mitigation measures that have been proposed to confront biological invasions, eradication projects are certainly the most drastic. In this short communication, a successful eradication project against a recently established population of the Italian wall lizard (Podarcissiculus) in Athens, Greece, is reported. To this aim, the Hellenic Herpetological Society received unforeseen aid from stray cats and, possibly, from the Οcellated skink (Chalcidesocellatus) and vegetation growth. Within three years, the initial thriving P.siculus population has shrunk to very few individuals.
