Previous Observations
The only known previous recorded observations of Nanuyalevu terrestrial wildlife were made by Dick Watling in 1969 and October 21-22, 1986, and Bill Beckon 26 September 1985 (2.5 hrs).

Results
This report records the species observed or reasonably expected on Nanuyalevu with their status; in addition a few species which might occur or are known to occur elsewhere in the Yasawas are listed. The only bird previously observed on Turtle which was not seen by me in 2001 (nor in 1986) is the White-rumped Swiftlet seen by Beckon in 1985. This may be an irregular visitor to Turtle Island. Similarly the absence of Pacific Harrier in 2001, is likely to be temporary, although, this raptor will not benefit from the current reforestation of the island.
The presence of a large number of feral cats is clearly the reason why the Banded Rail and other ground-nesting birds are extirpated or nearly so. My presumed observation of Banded Rail in 2001 was of footprints. Feral cats are also likely to be responsible for the rather low density of ground skinks.
The Marine Toad was not observed in 1986 and appears to have been introduced since that time. With permanent freshwater in the dams and long-lasting ephemeral wetlands being created, this species is likely to survive.
Rat trapping was surprisingly unsuccessful, the rat trap index was 4.5 captures per 100 corrected trap nights. Only Rattus exulans was caught, however, the presence of coconuts with characteristic Rattus rattus damage on them, indicates the presence of this species on the island. This is a pity as this species is highly predatory and destructive to wildlife.
