We used a citizen science-based data collection protocol to investigate foraging and nesting marine turtle populations in the Republic of Maldives. With the aid of citizen scientists, we collected nine months of data covering 12.5 % of the country, increasing the available sightings and nesting data by ~2,000 %. Data indicated that the Maldives are an important foraging habitat for juvenile and adult green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) turtles, though very few adult males of either species were reported.
