Technical Support to Melad in Rat Eradication, Biosecurity Motu Surveys, and Seabird Monitoring at Kiritimati, Kiribati, November 2023

Abstract

Field support and training was provided to Government of Kiribati staff at Kiritimati (Christmas Island) during 1-15 November 2023 as part of a Biopama project facilitated by BirdLife/SPREP. This project focused on rat eradication for biodiversity recovery, and associated outcome monitoring and capacity building. Specific objectives (and outcomes) included eradicating Kimoa (Rattus exulans) which had reinvaded Big Nimroona and SW Nimroona motu in 2017 (both motu were baited 6 days apart); confirming the status of invasives and birds on other key motu (checks of other significant motu indicated that Kimoa remain absent and rat-sensitive birds are thriving as a result); monitoring of endangered seabirds revealed that the Kiritimati population of Te Ruru continues to increase, while a large number of smaller motu provide secure nesting for Te Bwebwe ni Marawa; determining island and motu biosecurity needs (detailed biosecurity needs lists were completed and motu surveillance protocols adapted); and some additional training was completed for all.
