Tasmanian Tiger

Although I was called tiger, it looked like a dog with black stripes on its back and it was the largest known carnivorous marsupial of modem times. Yet, despite its fame for being one of the most fabled animals in the world, it is one of the least understood of Tasmania’s native animals. The scientific name for the Tasmanian tiger is Thylacine and it is believed that they have become extinct in the 20th century.

Fossils of thylacines dating from about almost 12 million years ago have been dug up at various places in Victoria, South Australia and Western Australia. They were widespread in Australia 7,000 years ago,but have probably been extinct on the continent for 2.000 years. This is believed to be because of the introduction of dingoes around 8,000 years ago. Because of disease, thylacine numbers may have been declining in Tasmania at the time of European settlement 200 years ago, but the decline was certainly accelerated by the new arrivals. The last known Tasmanian Tiger died in Hohart Zoo in 1936 and the animal is officially classified as extinct. Technically, this means that it has not been officially sighted in the wild or captivity for 50 years. However, there are still unsubstantiated sightings.

Hans Naarding, whose study of animals had taken him around the world, was conducting a survey of a species of endangered migratory bird. What he saw that night is now regarded as the most credible sighting recorded of thylacine that many believe has been extinct for more than 70 years.

"I had to work at night,"Naarding takes up the story. "I was in the habit of intermittently shining a spotlight around. The beam fell on an animal in front of the vehicle, less than 10m away. Instead of risking movement by grabbing for a camera, I decided to register very carefully what I was seeing. The animal was about the size of a small shepherd dog, a very healthy male in prime condition. What set it apart from a dog, though, was a slightly sloping hindquarter, with a fairly thick tail being a::straight continuation of the backline of the animal. It had 12 distinct stripes on its back, continuing onto its butt. I knew perfectly well what I was seeing. As soon as I reached for the camera, it disappeared into the tea-tree undergrowth and scrub.

The director of Tasmania's National Parks at the time, Peter Morrow, decided in his wisdom to keep Naarding's sighting of the thylacine secret for two years. When the news finally broke, it was accompanied by pandemonium. I was besieged by television crews, including four to five from Japan, and others from the United Kingdom, Germany, New Zealand and South America ,said Naarding.

Government and private search parties combed the region ,but no further sightings were made. The tiger, as always, had escaped to its lair, a place many insist exists only in our imagination. But since then, the thylacine has staged something of a comeback, becoming part of Australian mythology.

There have been more than 4,000 claimed sightings of the beast since it supposedly died out, and the average claims each year reported to authorities now number 150. Associate professor of zoology at the University of Tasmania , Randolph Rose, has said he dreams of seeing a thylacine. But Rose, who in his 35 years in Tasmanian academia has fielded countless reports of thylacine sightings, is now convinced that his dream will go unfulfilled.

"The consensus among conservationists is that, usually, any animal with a population base of less than 1,000 is headed for extinction within 60 years, "says Rose. "Sixty years ago, there was only one thylacine that we know of, and that was in Hobart Zoo, "he says.

Dr.David Pemberton, curator of zoology at the Tasmanian Museum and Art Gallery, whose PhD thesis was on the thylacine, says that despite scientific thinking that 500 animals are required to sustain a population, the Florida panther is down to a dozen or so animals and, while it does have some inbreeding problems, is still ticking along. "I'll take a punt and say that, if we manage to find a thylacine in the scrub, it means that there are 50-plus animals out there."

After all, animals can be notoriously elusive. The strange fish known as the coelacanth, with its proto-legs, was thought to have died out along with the dinosaurs 700 million years ago until a:specimen was dragged to the surface in a shark net off the south-east coast of South Africa in 1938.

Wildlife biologist Nick Mooney has the unenviable task of investigating all "sightings" of the tiger total 4,000 since the mid-1930s,and averaging about 150 a year. It was Mooney who was first consulted late last month about the authenticity of digital photographic images purportedly taken by a German tourist while on a recent bushwalk in the state, on face value, Mooney says, the account of the sighting, and the two photographs submitted as proof amount to one of the most convincing cases for the species' survival be has seen.

And Mooney has seen it all-the mistakes, the hoaxes, the illusions and the plausible accounts of sightings. Hoaxers aside, most people who report sightings end up believing they have seen a thylacine ,and are themselves believable to the point they could pass a lie-detector test, according to Mooney .Others, having tabled a creditable report, then become utterly obsessed like the Tasmanian who has registered 99 thylacine sightings to date. Mooney has seen individuals bankrupted by the obsession, and families destroyed."It is a blind optimism that something is, rather than a cynicism: that something isn't," Mooney says. “If something crosses the road, it's not a case of 'I wonder what that was? 'Rather, it is a case of 'that's a thylacine! 'It is a bit like a gold prospector's blind faith, it has got to be there'."

However, Mooney treats all reports on face value. "I never try to embarrass people, or make fools of them. But the fact that I don't pack the car immediately they ring can often be taken as ridicule. Obsessive characters get irate that someone in my position is not out there when they think the thylacine is there."

But Hans Naarding, whose sighting of a striped animal two decades ago was the highlight of "a life of animal spotting", remains bemused by the time and money people waste on tiger searches. He says, resources would be better applied to saving the Tasmanian devil ,and helping migratory bird populations that are declining as a result of shrinking wetlands across Australia.

Could the thylacine still be out there?"Sure,"Naarding says. But he also says any discovery of surviving thylacines would be "rather pointless". "How do you save a species from extinction? What could you do with it? If there are thylacines out there, they are better off right where they are.
