New Breeding Centre Offers Hope for Australia's Most Endangered Reptile
The Victorian grassland earless dragon, Australia's most imperilled reptile, now has a dedicated conservation breeding centre at Melbourne Zoo. The facility, which houses dozens of the critically endangered lizards, aims to safeguard the species from extinction after it was rediscovered in 2023 following 50 years of being thought extinct.
Zookeeper Zac Harkin describes the dragons as "pocket rockets" – fast, tiny reptiles with white racing stripes, small scales, and "fangy little teeth." Housed in open-air glass enclosures with living plants and artificial burrows, each dragon is paired genetically before winter to prepare for breeding season. Successful pairs can produce up to two clutches of about four eggs, each the size of a Tic Tac. Hatchlings emerge fully formed, slightly larger than a thumbnail and weighing less than a gram.
Critical Wild Population at Risk
The last wild population of the Victorian grassland earless dragon survives on a single plot of private grazing land west of Melbourne. This precarious situation concerns conservationists like Professor Brendan Wintle from the University of Melbourne, who notes that a single event – disease, fire, or predation – could wipe out the wild population. He urges state and federal governments to purchase the land to create a permanent conservation reserve.
A Victorian government spokesperson says the state is continuing to acquire land for the planned 15,000-hectare western grasslands reserve, with about a quarter secured so far.
Breeding Goals and Future Reintroduction
Garry Peterson, acting director of wildlife conservation and science at Zoos Victoria, says the goal is to breed more than 500 dragons – double the estimated wild population – to insure against extinction and enable reintroduction into the wild. "Success is having more populations established in the wild, because we have a conservation breeding program," he emphasizes.
The dragons once inhabited Melbourne suburbs like St Kilda, Moonee Ponds, and Sunbury, but development and agriculture reduced their grassland habitat to just 0.5% of its original extent. The new breeding centre, located near their original habitat in Royal Park, aims to reverse this decline.
Wintle warns that the species is "sitting right on the edge of the cliff," and losing the wild population would be "a great tragedy to lose a species twice." The breeding centre represents a critical step in preventing that outcome.
