ResumoVergara, G., Valenzuela, J. 2015. Presence of American mink (Neovison vison, Schreber 1777) in Chiloé, Chile: beginning of a biological invasion?. Ecosistemas 24(1): 29-31. Doi.: 10.7818/ECOS.2015.24-1.05 The American mink was first introduced into Chile in the 1930s and currently inhabits a wide geographical distribution. However, established populations have not been reported in many small island systems. On February 6th of 2013, a juvenile was discovered in Chacao, Chiloé, Chile. The Canal de Chacao represents the only biogeographic barrier to Chiloé Island, with a minimum distance to the continent of 2 km. It is assumed that the individual overcame this barrier on its own, entering by boat or via a third party. The introduction of a carnivorous mammal to Chiloé could have severe consequences for the ecosystems of the island. Preventive plans with the community and relevant public and private institutions represent an essential tool for managing this species and avoiding such impacts in Chiloé.
