One of Australia's most iconic endangered birds. The Southern Cassowary is the only animal large enough to disperse the seeds of over 150 rainforest plant species. Lose the Cassowary and you lose the forest.

A keystone species of the Wet Tropics. Flying foxes cross-pollinate trees that feed all other wildlife. Lose them, and the forest loses its midnight life force.

The Cairns Birdwing depends entirely on pristine forest habitat. Its caterpillars feed on a single native vine species, making habitat preservation critical to its survival.

The Wet Tropics houses over 30 frog species, many found nowhere else on Earth. Their health tells scientists everything about water quality and ecosystem balance.

Rainbow Lorikeets feed on nectar and pollen, moving from tree to tree. In doing so, they transfer pollen and drop seeds, helping the forest regenerate across wide areas.

The Palm Cockatoo is endemic to Cape York and New Guinea. Males craft tools from branches to drum on hollow trees, a behaviour unique among birds and a sign of high intelligence.
