Revisit Toreauta islet, in the Tahanea atoll, French Polynesia, to verify the site is pest free, and measure colonization by the endangered Tuamotu Sandpiper Prosobonia cancellata following rat removal. Investigate impacts of a 2011 swell event which caused vegetation to die off and a 50% crash of the sandpiper population. Plan for reintroduction of sandpipers to other suitable atolls.
