Santo, the largest island in the South Pacific nation of Vanuatu, is an extraordinary geographical and cultural microcosm, combining reefs, caves, mountains, and satellite isles—with human history that dates back 3,000 years. Collecting contributions from more than one hundred authors, The Natural History of Santo is the result of a 2006 Santo expedition, which brought together scientists, volunteers, and students from twenty-five countries. This lavishly illustrated book pays homage to the biodiversity of this “planet-island” and bridges the gaps between scientific knowledge, conservation, and education.
