Native Guava: On the Brink of Extinction
The once-thriving Native guava (Rhodomyrtus psidioides) is now teetering on the edge of extinction. A critically endangered species, it has been heavily impacted by the invasive myrtle rust, a fungal pathogen that has decimated its population.
Myrtle Rust: The Silent Killer
Myrtle rust, introduced to Australia in 2010, is a relentless threat to the native guava. It attacks the plant’s new growth, flowers, and fruit, causing severe defoliation and the loss of its ability to reproduce. Without intervention, this disease will likely wipe out the remaining native guava.
The Devastating Impact
Native guava is a member of the Myrtaceae family and is highly susceptible to myrtle rust. Studies show that native guava is the most affected plant by myrtle rust in Australia. Many of these trees are now reduced to root suckers, and entire populations have been lost. Without urgent action, the current generation could be the last.
Fighting Back: A Ray of Hope
Government’s Lifeline
In a race against time, the Queensland government is collecting cuttings from the few remaining native guava trees. This effort aims to preserve genetic diversity before it’s too late.
Building a Resilient Future
Working alongside the Queensland government, The Australian Network for Plant Conservation, and licensed nurseries, conservationists are developing myrtle rust-resistant plants. These new plants are crucial for the species’ survival.
Natura Pacific’s Role in Recovery
Natura Pacific is actively involved in these efforts, monitoring new native guava plantings in Tallebudgera Valley. The good news? The initial results show no signs of myrtle rust on these new specimens—a promising start on the road to recovery.
Saving a Species: The Road Ahead
The fight to save the native guava is far from over. But with a united effort from government bodies, conservation experts, and organisations like Natura Pacific, there is hope that this resilient species will make a comeback. The native guava’s future is uncertain, but the determination to save it is stronger than ever.
