Koala Population Recovery in Australia

March 20 , 2026 12 hrs 0 min 19 0
  • The population of koalas in Victoria has significantly recovered, leading to improved genetic diversity.
  • Earlier, excessive hunting and habitat loss caused a sharp decline, creating a genetic bottleneck in the species.
  • Rapid population growth in recent decades has increased gene reshuffling and reduced inbreeding problems.
  • This has helped improve overall health, reduce deformities, and enhance adaptability to environmental changes.
  • Koalas are marsupials that mainly feed on eucalyptus leaves and depend on forest ecosystems for survival.
