Site description (baseline)
Kiritimati is the largest of the Line Islands, and by total land area is the largest atoll in the world. This ancient atoll consists of a large, flat, island with a shallow tidal lagoon opening to the northwest. At the inner (eastern) end of the lagoon there are several hundred smaller, land-locked, lagoons.

Key biodiversity
The island supports globally-important populations of a number of seabirds, and is also home to the endemic, restricted-range Kiritimati Reed-warbler
