This paper is a compilation and analysis of all vascular plants that have been reported on Kiritimati (Christmas) Atoll in the Northern Line Islands of the Republic of Kiribati. It is based on field inventories
conducted by the authors on six field visits to the atoll between 1996 and 2012 plus available published
and unpublished records of vascular plant collections and observations made on the atoll.
Two soils investigations were investigated in the 1960s, but no additional information on the soil resource of the island has been produced since that time. In this study, 15 soil types were described and analyzed. Where possible, comparison has been made with previous works.
These guidelines provide a framework for bird species monitoring and invasive species surveillance at Kiritimati.
