Introduction: Species Notes for this Location:
Management Notes for this Location:
Pacific rats (Rattus exulans) were considered having a significant impact on the biodiversity and ecosystem of Rose Island, Rose Atoll. Rose Atoll is a nesting site of the 'critically endangered' hawksbill turtle (see Eretmochelys imbricata in IUCN Red List of Threatened Species), the endangered green sea turtle (see Chelonia mydas in IUCN Red List of Threatened Species), and several species of migratory seabirds. An eradictaion programme was undertaken during 1990-91. Talon-G in a product called WeatherBlok was used as bait on Rose Island and proved to be highly successful. A remnant population of rats was a major concern and an eradication operation was planned using bromethalin as bait as a follow up to WeatherBlok. For details on the eradication project please see Ohashi & Oldenburg, 1992.
An attempt has been made to eradicate the Pacific rat from Rose Atoll (6 ha), using either brodifacoum or bromethalin, and trapping (Island Conservation and Ecology Group, 2004). Last Modified: 1/08/2006 3:59:03 p.m.
