Impact of pigs on the Auckland Island ecosystem
Mainland New Zealand has numerous examples of introduced plants and animals that have impacted upon native ecosystems. The Auckland Islands are no different.
Soon after European discovery in the early 1800s, pigs, rabbits, cattle and goats were gradually released on to the Islands. Unsurprisingly, these animals have had an impact on the ecosystem - carving out tracks, grazing on plants, as well as predating and competing with invertebrates and birds.
An assessment task, marking schedule and powerpoint linked to the Science 1.12 - Biological impact of an event on an ecosystem achievement standard is available for teachers and students.
