What to know about Scientific Research

Researchers from Adelaide University and Kangaroo Island institutions studied how nest box entrance sizes affect the occupancy of rare little pygmy-possums versus common western pygmy-possums. The findings suggest that a 1-millimeter difference in entrance size can help exclude the more common species, though further research is required to determine long-term viability and risks.

Tiny nest box change could help rare pygmy-possums after bushfires Lisa Lock Scientific Editor Robert Egan Associate Editor A 1-millimeter difference in the size of a nest box entrance could help rare little pygmy-possums recover after bushfire, according to…

Why it matters

Two species of pygmy-possum are found on Kangaroo Island: the common western pygmy-possum and the rare little pygmy-possum.

Common ground

The little pygmy-possum is known to be strongly affected by fire and lost 88% of its recorded range on the island during the 2019–20 Black Summer bushfires.
