Thirteen native animal species have returned to New South Wales conservation reserves after a decade. These species had been locally extinct and are now breeding successfully within predator-proof fences. This conservation success is the result of a ten-year partnership involving government and scientific organizations. The state has now extended this vital conservation agreement for another ten years. Future efforts will focus on expanding these reintroductions beyond fenced areas.

Marine biologists rescued rare Hawaiian coral fragments from Kaneohe Bay in 2015. These fragments were grown into mature colonies using a land-based nursery method. The grown corals were then returned to their natural habitat in Kaneohe Bay. Field checks confirmed the reintroduced corals successfully adjusted to their surroundings. This project demonstrates the effectiveness of coral arks for preventing species extinction.

In 2012, 28 Tasmanian devils were introduced to Maria Island as an insurance population against facial tumour disease. The devils thrived, reaching up to 90, but experts say their presence came at a heavy cost to local wildlife. A survey later found Maria Island’s little penguin colonies had disappeared, wiping out an estimated 3,000 breeding pairs.
