PHOENIX ISLANDS PROTECTED AREA MANAGEMENT PLAN<br />

<strong>Chapter</strong> III. Background, 3. Terrestrial Resources<br />

Draft 1 March 2007<br />

Pierce et al (2006) suggested the use of aerial application of rat bait on the larger Phoenix<br />

Islands.<br />

ABARIRINGA (CANTON, KANTON)<br />

Maude (1937) reported rats on Abariringa (Canton). These rats did not appear to more<br />

numerous than on any of the Gilbert Islands.<br />

Gardner (1938) provided an account of the rats encountered during the 1937 solar eclipse<br />

expedition. Rats were small and unbelievably tame and had no hestitation to take food from<br />

a washpan held by hand. Gardner (1938) noted that rats were probably more common than<br />

hermit crabs. A shotgun was brought on that expedition to kill rats, but with little impact. In<br />

addition, rat poison was mixed and presented to rats. Hundreds of rats should have died, but<br />

this did not seem to dent the rat population. Gardner (1938) speculated that rats on<br />

Abariringa (Canton) lived on bird eggs which resulted in bird populations on Abariringa<br />

(Canton) being less than on Enderbury.<br />

Rats were found on Abariringa (Canton) (Hydrographic Office 1940; Bryan 1934). Bryan<br />

(1941 and 1942) specified that Polynesian rats were found on Abariringa (Canton). Van<br />

Zwaluwenburg (1941) reported that where there was ground cover, the ground-nesting<br />

Polynesian rat was present in astonishing numbers. This rat fed on vegatable food including<br />

tree bark, and fruits and flowers of Scaevola.<br />

Van Zwaluwenburg (1941) reported three flea infested dogs that were brought to Abariringa<br />

(Canton), but none had any fleas when examined. There were no harbor fleas on rats.<br />

In 1946, feral canines (dogs) were first observed on Abariringa (Canton) (Oates 2003). These<br />

were probably left by the U.S. Army’s Canine Corps (1942 to 1943). They were observed<br />

swimming the lagoon from north to south.<br />
