Alien and invasive terrestrial vertebrate species on Corfu, Ionian Islands, Greece

Abstract. The Ionian Island of Corfu is rich in both species and habitats, but is also under pressure from heavy tourism, substantial water abstraction, and increased development, all of which have caused both loss and fragmentation of habitats. In addition, invasive alien species (IAS) constitute a global problem and may cause substantial problems for indigenous wildlife, especially on islands. To be able to successfully control IAS it is important to identify them, report their status, and raise awareness as early as possible. Here we present the status of ten alien species reported from Corfu, four of which are considered as invasive, the coypu (Myocastor coypus), the raccoon (Procyon lotor), the Siberian chipmunk (Tamias sibiricus), and the American pond slider (Trachemys scripta). Measures required as outlined by the EU Working Group on Invasive Alien Species are briefly discussed.
