Tranqui is an island of the Chiloé Archipelago in southern Chile. It has three sectors: San Jose, Tranqui Nepué and Sentinel, all with small populations. A significant part of its forest still has not been touched by the subsistence agriculture which forms the bulk of the province's rural economy.[1]
