Threatened Species of Shark Bay

Shark Bay World Heritage Area is a refuge for some of the world’s most endangered animals and plants. Its isolated islands and peninsulas have been largely spared the feral predators and habitat destruction that wreaked havoc on mainland Australia. The importance of these habitats in protecting vulnerable wildlife, and providing scientific information on the impact of habitat change, was a major factor in Shark Bay being declared a World Heritage site.

Two of Shark Bay’s islands, Bernier and Dorre Islands, are the last stronghold for five critically endangered land mammals – four of which occur in the wild nowhere else on Earth.

An ecological restoration project is underway on the largest of Shark Bay's islands, Dirk Hartog Island. This project aims to restore habitats, remove feral cats and reintroduce ten species lost from the island during its pastoral era. It will also introduce two native species not previously  known to occur on the island.

In other parts of Shark Bay, cats, foxes and grazing stock have been removed in order to allow the ecosystem to rejuvenate. Captive-bred animals have been introduced to places such as Francois Peron National Park as part of Project Eden, a local conservation initiative.

The Australian Wildlife Conservancy has established a wildlife sanctuary on Faure Island. After removing cats and goats they successfully introduced a number of species. Find out more here.
