For decades, the Tasmanian tiger was portrayed as Australia’s most feared livestock predator. Farmers blamed it for the sheep’s deaths, newspapers described it as a threat to agriculture, and the Tasmanian government eventually paid a cash reward for its vandalism. When the last known thylacine died at Hobart Zoo in September 1936, the species had disappeared from the wild. Yet modern research suggests the animal may have been convicted in the court of public opinion long before the evidence was properly scrutinized. Historical bounty records, population models, body size analyzes and disease surveys now suggest that the thylacine’s reputation as a devastating sheep killer may have been overstated. The real story behind the Tasmanian tiger’s extinction appears to be much more complicated and tragic.
More than 2,000 bounties paid as farmers believe thylacine is killing sheep
In the late nineteenth century, as sheep farming expanded in Tasmania, the campaign against the thylacine intensified.According to official government records, more than 2,000 bounties were awarded for hunting thylacines from 1888 to 1909. Farmers, livestock keepers and politicians often blame the thylacine for massive livestock losses.The problem is that this reputation is largely based on assumptions rather than direct observation.According to Landcare Tasmania, many of the accusations are based on finding dead sheep and blaming the attacks on thylacines, without confirming which predator was responsible. Dingoes found in parts of Tasmania are also capable of killing livestock and often leave similar evidence.The size of the animals also adds fuel to the debate. Most adult thylacines weigh between 15 and 30 kilograms. While they were indeed capable predators, they were much smaller than many contemporary descriptions would suggest.
New population model suggests hunting alone may not explain collapse
A 2021 analysis examined more than 1,200 historical sightings and reports related to the species.Researchers from the University of Tasmania’s School of Natural Sciences used statistical modeling to reconstruct the decline of the thylacine population and test different extinction scenarios. The results suggest that while bounty hunting undoubtedly reduces numbers, persecution alone can hardly explain the rapid and widespread disappearances observed across Tasmania.Research ‘The extinction of the thylacine“The evidence found is consistent with a population already facing severe stress in the early twentieth century.In some areas, sightings are declining faster than expected if hunting were the only factor involved. This raises the possibility that another process occurred concurrently with human persecution.
Disease theory centers on strange reports from past decades
One of the most interesting explanations comes from historical reports collected by researcher Robert Padel during his research “The last straw for the thylacine: a recent epidemic of mammalian extinctions.’In a review of the evidence for the thylacine’s extinction, Padel recorded descriptions of animals that appeared unusually weak, thin, or unhealthy. Witnesses said that in areas where food resources should be available, some people suffered from hair loss and poor health.The pattern is similar to what scientists would expect from an epidemic that spreads through small, dispersed populations.While no biological samples can conclusively prove the outbreak occurred, Padel believes that epidemics remain one of the few explanations that can explain the speed and geographic scope of the disease’s decline.Importantly, this theory does not replace hunting as the cause. Rather, it suggests that persecution may strike at a population already weakened by another threat.
Tasmanian tiger extinction could be a chain reaction
The image of the thylacine as a sheep-killing menace helped justify decades of organized persecution. Once bounties are introduced, every dead animal becomes another reason to eliminate the predator.However, the evidence available today points to a series of events rather than a single cause. Hunting wipes out thousands of animals. Habitat pressure reduces available territory. Minority populations are becoming increasingly vulnerable. Disease outbreaks may further weaken survivors.The tragedy is that many of these questions were investigated only after the species had disappeared.By the time scientists began to take a hard look at whether the thylacine’s reputation matched reality, the world’s largest known carnivorous marsupial had become an icon of extinction. What remains is a cautionary lesson about how myths, economic fears and incomplete evidence can affect the fate of an entire species.
