Introduced Invasive species - (Vanuatu) : animals

Early settlers brought in animals (e.g. cattle, pigs, goats, cats, chickens and dogs) for food, pets and hunters for their survivals. Some of the animals were not well managed that they become wild (feral) and become problems. Feral pigs, cattle, goats tramp and graze on forest plants and garden crops that may result in desertification in some areas. Their manure deposits in water cause algal growth that makes water bodies look dirty. Feral and domesticated cats and dogs kill native birds, reptiles and insects, which leads to great loss of native wild life throughout the islands.
