Poncelet's Giant Rat

Solomys ponceleti

Declining

Overview

Poncelet's giant rat or Poncelet's naked-tailed rat is a species of rodent in the family Muridae. It is found on Bougainville Island, part of Papua New Guinea, and nearby Choiseul Island in the Solomon Islands.

Solomys ponceleti faces severe threats from extensive logging operations that have fragmented and destroyed much of its lowland forest habitat across the Solomon Islands. The species' restricted range and small population size make it extremely vulnerable to habitat conversion for agriculture and palm oil plantations. Introduced predators, particularly feral cats and rats, pose additional pressure on this ground-dwelling rodent, while climate change threatens to alter the composition of remaining forest fragments.

Threat summary

Habitat

Solomys ponceleti inhabits lowland tropical rainforests and secondary forest areas in the Solomon Islands, typically found in areas with dense understory vegetation.
