• Couple clear 4,000 hectares of pests; vanished Australian animals return

  Ecologists Rebecca West and Reece Pedler led eradication efforts to remove rabbits, feral cats, and foxes from Sturt National Park in north-western New South Wales. Operating under the collaborative Wild Deserts project, the initiative returned six locally extinct mammal species to revive degraded desert soils and vegetation dynamics. These restored populations are now expanding into broader landscapes where introduced predator numbers remain actively suppressed.
