    The victims were carried in one by one, their paws and fur burned, suffering from lack of water and fear. Their caretakers bandaged their wounds and laid them in baskets with the only thing that was familiar -- the leaves of a eucalyptus (桉树) tree.

As catastrophic fires have burned more than 2 million acres in Australia, dozens of koalas have been rescued from smoky and burning trees and ashen ground. "They are terrified," said Cheyne Flanagan, clinical director of the Koala Hospital in Port Macquarie, the only facility of its kind in the world.

Koalas, unlike kangaroos, birds or snakes, do not flee from fires but instead climb trees to the top, where they can curd themselves into a ball for protection and wait for the danger to pass. But during high-intensity fires, such as those that have burned in recent weeks, the animals, conservationists said, are far less likely to survive. Even if the fire itself does not reach the tree top, the animals may overheat and fall to the ground, where they can be burned to death.

The suffering of the koala -- a national symbol of Australia -- has raised questions among conservationists and scientists about what it will take to preserve biodiversity in a country increasingly prone to intense fire, extreme heat and water shortage. While koalas have evolved to exist alongside wildfires, the animals are facing new threats not just from climate change but also from human development, which has affected local populations, impairing their ability to survive fires.

"We have these unique animals not found anywhere else on this planet, and we're killing them," Flanagan said. "This is a big wake-up call."
