In 2014 the I-Kiribati government established a twelve-nautical-mile (22-kilometre; 14-mile) exclusion zone around each of the southern Line Islands (Caroline, Flint, Vostok, Malden, and Starbuck) preventing fishing in the surrounding waters.

[2] There is a small landing in the north-west of the reef blasted in, which is marked by a 9 meter tall concrete obelisk on the beach.

[3] Flint island was rediscovered on April 8, 1809, by the American captain Obed Chase in ship Hope (belonging to Edmund Fanning).

It was leased by the British to Houlder Brothers and Co. of London who carried out guano digging in the central part of the island from 1875 to 1880 under field manager John T. Arundel.

[2] On 3 January 1908 a total eclipse of the sun was observed on the island by two expeditions, one from the Lick Observatory in California, and one from Australia and New Zealand which included Francis McClean and Henry Winkelmann.

The jungle is moist and makes prime habitation for Emoia Impar, which inhabit most of the island at a density of over 30 per square meter.

Sooty Terns, Red-Footed Boobies and Frigatebirds nest in the palm trees around the beaches, and Coconut Crabs live in the fallen trees in the jungle, which made it easier for them to reproduce to cover the island at a density of 1 per square meter, which could potentially give Flint Island the largest population of Coconut Crabs in the world, the other most likely contender would be South Islet in Caroline Atoll.
