In the heart of Australia’s rainforests, a newly discovered tree species has caught the attention of scientists for its unusual and deeply disturbing properties. The newly discovered tree, called the “Zombie Tree”, is alive, but unable to reproduce in the wild.
The tree, called Rhodominia zombie, is unable to reproduce because it has been attacked by a highly contagious fungus. As a result, the tree is unable to produce flowers, fruits and seeds, putting its existence on the brink of extinction. But the question is, can this species be saved before it completely disappears from the face of the Earth? It is not just the tree, but the complete balance in nature.
What is Australia?Zombie tree ‘
The term “zombie tree” is used to refer to a species of tree called Rhodamnia zombi, which is found in rainforests and was first discovered in Queensland in 2020.
The tree was recently named by experts because although some of the trees are alive, they are unable to reproduce naturally.Research by the University of Queensland found the tree was “alive but unable to reproduce” due to recurring infections that made it impossible for the trees to develop new growth needed for reproduction.For this reason, this species is considered functionally extinct, despite the presence of some trees.
Botanist Professor Rod Fincham described the trees by saying that without any intervention, trees are “the living dead”.
Myrtle rust : the Fungal disease Extinction drive
The main threat to the zombie tree is a fungal disease called myrtle rust. This disease is caused by a fungus known as Austropuccinia psidii. This disease targets the myrtle family, which includes several native Australian species, such as eucalyptus and tea tree.Myrtle rust can spread quickly through fungal spores that can be transmitted by wind, insects, animals, and even humans. The disease then begins to affect the plant, causing yellow or orange spots to appear on the leaves and young growth. This ultimately results in the plant being unable to produce flowers or seeds, thus stopping the plant’s life cycle.However, what made matters worse in Australia was that native plant species were unable to defend themselves against the disease.
This means, according to Professor Fincham, that these species, which include the myrtle family, such as the eucalyptus tree and the tea tree, were called “naïve hosts” because they did not have time to develop resistance to the disease.
Scientific efforts to save the zombie tree
While scientists face the problem of the rapid decline of the Rhodhamnia zombie, they have come up with various solutions to prevent its extinction. One of the first solutions to put into practice is to clone the few remaining trees.
This will be done by cultivating the mind in controlled environments.There has also been research into treatments that will be able to protect trees from infection. This includes the use of fungicides, as well as RNA-based treatments, which will be able to enhance the tree’s ability to fight diseases.Another solution to Rhodomania zombie decline is to grow seedlings in controlled environments where the fungus is not active.
We hope that, over time, this will enable some of them to become immune to the fungus and thus be able to return to their natural habitat. This will be done, as ongoing studies have shown, in order to “plant disease-free seedlings in protected sites to ensure the future of the species.”

Why does this matter outside of one type?
However, the zombie tree crisis presents us with a larger environmental problem. In fact, myrtle rust affects not just one species, but many species of the Myrtaceae family, and we have to consider the loss of biodiversity in Australia’s rainforests.The zombie tree therefore presents us with the impact of invasive species, which can threaten the entire ecosystem, especially when native species have no defense. In fact, it refers to the challenges that have emerged in the wake of globalization and the effects of climate change, which have facilitated the spread of diseases.However, the battle to save Australia’s zombie tree reminds us of the fragility of nature. While this species is on the verge of extinction, science and innovation offer us a sense of hope. Indeed, the outcome of this race will not only determine the fate of this unique species, but will also have implications for how we choose to confront other environmental issues in the near future.
