摘要: Abstract Many otters ( Lutra lutra ) are killed on roads each year. At present, it is not possible to determine whether or this has an impact otter populations, they declining, recovering stable. New should be designed with the needs of in mind areas which likely recolonise as well those where already present. It reduce number being existing by appropriate mitigation but may expensive and important consider costs benefits. Dead a valuable resource for population studies there great value collecting carcases post mortem studies. also record sites all road deaths inform priorities mitigation. Riassunto Incidenza del traffico veicolare sulla mortalita della Lontra. Molte lontre sono uccise sulle strade ogni anno. Attualmente, e impossibile valutare se tale fattore ha un impatto popolazioni di Lontra tali declino, recupero o stabili. Le nuove dovrebbero essere tracciate tenendo conto delle necessita sia aree probabilmente soggette alla ricolonizzazione dove la specie gia presente. E’ possibile ridurre rete viaria esistente mediante appropriati interventi mitigazione, per i quali importante valutarne costi benefici. carcasse morte particolarmente utili studi popolazione loro siti rinvenimento consentono definire le prioritarie cui adottare misure mitigazione.
