Imagine a world where one of Australia’s most iconic creatures, the echidna, quietly vanishes without us even realizing it. This isn’t just a far-fetched scenario—it’s a real concern for scientists. Despite their fame, echidnas remain shrouded in mystery, and one of the biggest unknowns is their population size. This lack of data has experts on edge, fearing the species could decline unnoticed. But here’s where it gets even more urgent: urbanization, land clearing, and climate change are looming threats, and without a clear picture of their numbers, we’re flying blind.
Enter Dr. Kate Dutton-Regester, an ecologist from the University of Queensland, who is spearheading a groundbreaking population survey in southeast Queensland. Her mission? To establish a baseline for echidna numbers—something that, surprisingly, doesn’t exist yet. ‘Echidnas are Australia’s most widespread mammal, but widespread doesn’t always mean abundant,’ she explains. ‘We need this baseline to monitor their health over time and catch any declines before it’s too late.’ The stakes are high: without action, we risk waking up in 10, 20, or even 40 years to find these creatures have become a rarity.
But here’s where it gets controversial: While echidnas are resilient, they’re also incredibly vulnerable. Their sensitivity to heat, combined with a breeding season limited to just a few months (May to October), makes them particularly susceptible to rising temperatures. ‘If climate change shortens their breeding window, it could severely impact their ability to maintain, let alone grow, their population,’ Dr. Dutton-Regester warns. And this is the part most people miss: echidnas already reproduce only every two to six years in the wild. Add habitat fragmentation, vehicle collisions, and food scarcity into the mix, and the future looks increasingly uncertain.
To bridge this knowledge gap, Dr. Dutton-Regester has launched EchidnaWatch, a citizen-science project in partnership with the Wildlife Preservation Society of Queensland. The initiative encourages the public to report sightings, scats (yes, echidna poop!), and diggings via the iNaturalist app or the EchidnaWatch website. ‘Every piece of data helps us build that critical baseline,’ she says. Even deceased echidnas are vital to log, as they reveal hotspots for road accidents, potentially leading to life-saving signage.
Public engagement is key, and Dr. Dutton-Regester’s team is leading the charge with field trips and workshops across southeast Queensland. During a recent search in Kimberley Forest at Shailer Park, participants didn’t spot an echidna but learned to identify burrows and scats—a small but significant step in conservation. ‘I’ve only seen an echidna once in the wild,’ shared participant Belinda Neal. ‘I want to know how I can help ensure future generations get that chance too.’
What makes echidnas truly fascinating—and worth saving—is their uniqueness. Alongside the platypus, they’re one of only two mammals that lay eggs. ‘They’re my Roman Empire now,’ Dr. Dutton-Regester jokes, highlighting their temporary pouch (developed only during pregnancy) and other quirks. ‘There’s so much about them that’s unlike any other mammal.’
Here’s the thought-provoking question: If we can’t protect a creature as distinctive and beloved as the echidna, what does that say about our ability to safeguard biodiversity? Share your thoughts in the comments—are we doing enough, or is it time to step up our efforts? The clock is ticking, and the echidnas are watching.
