    Management Notes for this Location:
    The Pacific rat (Rattus exulans) was eradicated from Rurima Island (4.5 ha) in eradication trials carried out in 1983-1984, in a programme led by I. McFadden (McFadden and Towns, 1991; McFadden, 1992). 1080-impregnated kibbled maize was used dispensed from gravity fed silos, but the rats did not take the bait, perhaps because of the taste of dyes used in manufacture. This was replaced with undyed kibbled maize impregnated with bromadiolone. Eradication was probably achieved within three months (Thomas and Taylor, 2002).
