Flora and fauna

Rawaki's flora and fauna

Rawaki has been described as being ham or pear shaped. Its highest elevation is approximately six meters. It is treeless, being covered mostly with herbs and grasses, and thus forms an excellent landing and nesting site for migratory seabirds and turtles. Unlike many other Pacific islands, no rats were noted on Rawaki during a 1924 scientific expedition. A colony of feral

rabbits Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit sp ...

was introduced in the nineteenth century, but was eliminated in 2008. Rawaki has its own species of seabird tick, ''Ixodes amersoni''. It also boasts various species of flies, moths, leafhoppers, green bugs, and spiders. Sea birds consist of sooty, grey, and white terns; frigates, petrels and shearwaters; boobies, migratory plover and curlew. Rawaki has never been invaded by rats so the bird populations have survived.

Rawaki's reefs

The 2000 surveys (Obura, et al.) identified that sites on the reef averaged 60% Live Coral Cover with

coralline algae Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of re ...

as the next dominant cover category in shallow water. Unlike other islands in the Phoenix Group sites, branching corals were not dominant at Rawaki with highest cover contributed by encrusting/submassive colonies or coral plates. Massive corals were also significant in abundance, reflecting the origin of the coral bommies that form the main reef substrate of the sites. The most abundant coral species at Rawaki Island were: ''
