Exploring the Impacts of Climate Change at Mungo National Park with Roger Smith

When you ask Roger Smith, co-founder of Echidna Walkabout Nature Tours along with Janine Duffy, about climate change at Mungo National Park, he cites an example. “To help people understand the impacts of climate change in a certain area, I usually profile a creature,” he says. “I’ve been visiting Mungo for over five decades and have noticed the number of emus over the last few years has declined.”

Mungo National Park was recognised and included in the Willandra Lakes World Heritage Region in 1981 for its record of Aboriginal settlement (experts hypothesise that the park is home to the oldest culture on earth after the discovery of Mungo Lady and Mungo Man), its strong representation of Australian megafauna, and its important geological attributes.

The park – which spans 111,000 hectares – is also famous for its diverse bird life. “Many serious birdwatchers come here to see the 150 or so species of birds we have here,” Roger says. “The Pink Cockatoo, Chestnut-crowned Babbler and a staggering diversity of parrots are all highlights.”

Emus, are one of the more popular birds to spot, however, in April 2021 Roger saw only eight emus over three days. “A few years ago, at the same time of the year, I’d usually see hundreds,” he says. “One of the most important things we do when we assess the impacts of climate change is to monitor the health of the environment, and one of the best ways to do this is to track and record the number of creatures we see.”

Although the majority of the emus seemed to have moved on to ‘greener pastures’ for now, Roger is confident that they will return (probably in reduced numbers), explaining that animals naturally move between areas to survive different booms and busts. “Australian wildlife is capable of dealing with dramatic changes in the environment,” he explains.

In the meantime, spotting an emu feels just that little bit more special when in Mungo, and Roger says that by coming along on the Mungo Outback Journey, guests are already partaking in important conservational work. “By walking around, looking for seeds, looking for wildlife, and logging the species that we see, guests are already doing a great deal,” he says. “However, for Mungo to lose so many of its emus is extraordinary, and a warning that even Australia’s toughest bird is having problems with climate change."
