Non-native amphibians and reptiles recorded in the Faroe Islands since 1950

Abstract

The Faroe Islands, a North Atlantic archipelago historically devoid of native amphibians and reptiles,
have experienced multiple human-mediated introductions of several taxa over the past century. Based on interviews,
media reports, and photographic records, we herein present the first comprehensive overview of these introductions.
Three species of amphibians (Rana temporaria, “Pelophylax esculentus” [actually a hybrid between P. lessonae and P.
ridibundus], and Bufo bufo) and at least five species of reptiles (Podarcis siculus, Iguana iguana, Gekko cf. chinensis,
Sternotherus odoratus, and various snakes have been recorded. Of these, only R. temporaria has established a viable and
expanding population, particularly on Nólsoy and parts of Streymoy, via intentional and accidental translocations by
local residents. No other species has shown any evidence of breeding success. This report highlights how increasing
globalization, trade, and human mobility continue to facilitate the introduction of non-native fauna to the Faroe
Islands despite a 2004 ban on exotic animal imports.
