to document the island's human history, assess recovery of the island's flora and invertebrate fauna since the removal of sheep and the world's largest rat eradication programme, study the island's plentiful but little understood streams and characterise the unusual stream fauna, and reconstruct past environmental conditions and deduce long term climate change from tarn sediment cores. The expedition was run by the 50 Degrees South Trust, a charitable organisation established to further research and education on New Zealand's Subantarctic Islands, and to support the preservation and management of these World Heritage ecosystems. The expedition and the programme outputs can be followed at the CIBE website.
