The Italian action plan for the endangered Eurasian otter Lutra lutra

Abstract Although recent evidence of the species recovery has been reported for many European countries, in Italy the Eurasian otter Lutra lutra is still considered endangered. Otter populations are confined to few river basins in the southern part of the peninsula and these are both geographically and genetically isolated from other European populations. This critical situation led the Italian Ministry of Environment to promote the production of an Action Plan for the otter in Italy, whose methods, aims and actions are briefly summarized. Riassunto Il Piano d'Azione Nazionale per la Lontra Lutra lutra Nonostante i segnali di recupero segnalati in molti paesi europei, la lontra Lutra lutra e ancora una delle specie piu minacciate della fauna italiana, in virtu delle piccole dimensioni della popolazione e del suo isolamento , sia geografico, sia genetico, dal resto delle popolazioni europee. Sulla base di queste considerazioni il Ministero dell’Ambiente e della Tutela del territorio e del Mare ha recentemente promosso la realizzazione di un Piano d’Azione Nazionale per la Conservazione della Lontra, i cui contenuti, obiettivi, e azioni sono riassunti in questo lavoro. doi:10.4404/hystrix-21.1-4483
