Koalas (Phascolarctos cinereus), the iconic marsupials of Australia, are not migratory but exhibit small-scale movements within their territories. These movements are influenced by the availability of eucalyptus leaves, their sole food source. Koalas may shift trees or areas depending on seasonal changes in leaf quality and water content, especially during dry spells.
In times of extreme drought or habitat loss, koalas are known to travel longer distances to find suitable eucalyptus groves. Their limited mobility and dependence on specific tree species make them highly vulnerable to habitat fragmentation. Wildlife corridors and habitat restoration are vital for allowing koalas to safely traverse between feeding grounds.
