Construction has begun on a 10-kilometre conservation fence at Wilsons Promontory National Park in Victoria, Australia. The project is a major step toward creating the Prom Sanctuary.The fence is designed to keep invasive foxes, feral cats, and deer out of a protected area. The park is home to more than 150 threatened plant and animal species across forests, woodlands, dunes, and coastal habitats.Rangers are designing special gates so wombats can still move through the landscape. Cameras will also monitor the narrow places where animals might enter or leave.The fence has been more than 50 years in the making. It is expected to be finished late this year, alongside pest control, deer removal, habitat restoration, and ecological monitoring.
