In the areas where work has been completed to remove senescent forest stands of invasive alien species (mainly eucalyptus) on the island of San Martiño (Galicia), LIFE INSULAR is monitoring the conservation status of the target habitats. Initial results have shown an improvement in their surface area, composition, and structure, as well as in their future prospects. This translates into an improvement in their conservation status, which benefits the natural heritage and biodiversity of the island territories.
