Three species of bat are the only native mammals: two large fruit bats (Samoa flying fox and white-naped flying fox) and a small insectivore, the Pacific sheath-tailed bat.
They serve an important role in pollinating the island's plants.
The sheath-tailed bat was nearly eliminated by Cyclone Val in 1991.
Native reptiles include the pelagic gecko, Polynesian gecko, mourning gecko, stump-toed gecko, Pacific boa and seven skink species.

A major role for the park is to control and eradicate invasive plant and animal species such as feral pigs, which threaten the park's ecosystem.
There are several bird species, the most predominant being the wattled honeyeater, Samoan starling, and Pacific pigeon.
Other unusual birds include the Tahiti petrel, the spotless crake, and the rare (in this locality) many-colored fruit dove.
