Western Pebble-mound Mouse

Pseudomys chapmani

The Western Pebble-mound Mouse is a native rodent and a true ecosystem engineer, found only in the rocky ranges of the Pilbara region in Western Australia. It is not a pest. This species is renowned for constructing large, impressive mounds of pebbles over its underground burrow systems. These mounds, which can be up to 10 square metres in area and contain many thousands of stones, are actively maintained by generations of mice and can be hundreds or even thousands of years old. The stone layer is believed to protect the mice from predators, buffer them from extreme temperatures, and create a humid microclimate in their burrows, which is critical for preventing dehydration in their hot, arid environment.
