New Zealand island ecosystems have been devastated by invasive species. In response, over the last 25 years all invasive mammals have been eradicated from more than 100 islands. Ecological restoration of these systems is now underway, including reintroductions of invertebrates, amphibians, reptiles, and birds. These enterprises clearly illustrate what Lawton called the “science and non-science” of conservation biology. The science of island restoration revolves around the technical complexities of eradications and the demographic and genetic issues associated with small populations. The non-science of island restoration arises from activities associated with some species translocations, debate about ecosystem composition, and divergent views about restoration goals. These issues are illustrated by recent studies of the genetic effects of reptile translocations and analyses of cross-cultural views of coastal restoration. As ecological restoration becomes more complex, there is an increasing need to develop a transparent system for dealing some of the value-judgments required for such projects.
