This species qualifies as Vulnerable
as it is only found on one small island where it remains at risk from
the accidental introduction of exotic species.
The species has apparently adapted
to the presence of Pacific rat Rattus exulans. However, the
accidental introduction of a more aggressive predator, such as another Rattus
species, could be devastating, and introduced diseases, such as avian
malaria and pox, are another potential threat. The introduction of
exotic plant species could have serious consequences for the native
vegetation4 and therefore for this species too.
designated a World Heritage Site. Rat eradication has been investigated
and is feasible but difficult because of the island's isolation1.
*Periodically resurvey to monitor
numbers and trends. *Ensure that further alien species are not
accidentally introduced to
. *Consider the eradication of rats from Henderson1.
*Re-attempt the eradication of rats from nearby
, and consider
translocating the species there when it becomes rat-free1.
