The Tree Mouse Pogonomys sp. was not recorded live in Australia until 1974, although it was known from the fossil record. It is substantially under-recorded in standard fauna surveys because it is loath to enter traps on the ground. However, there have been many casual sightings of the species, and these have generated the body of information presented here. Along with the few museum specimens, such sightings indicate that the Tree Mouse occurs in rainforests of Cape York Peninsula and the Wet Tropics. It nests in burrows but spends its time arboreally, in low vegetation to the upper canopy. Observations reported herein suggest the species is primarily a fruit and leaf eater. Casual observations by citizen scientists will continue to be an important source of information for this little-known species, so we provide guidelines on the most useful details that they should collect.
