Are thylacines still around? Consider this..
I had to jump in and reply to this one, even without reading the rest of the thread. Forgive me if I double-up on info.
jelle - i personally don't hold "sightings" even be them in large quantities as very substantial proof of an animals existance.
Fair call. I don't know how often the rhino was sighted in SE Asia until it turned up in front of a camera trap. The South American short-eared dog went over 20 years without even a sighting before being recaptured by a camera trap. The record-taker would have to be Australia's Gilbert's potoroo - in the order of 115 years between drinks, *despite* concerted searches! Wallabies kicking on after 60 years don't rate a mention because Regular Jo probably couldn't pick a rare one from a common one, but if the species were highly distinct - as with the thylacine - then maybe you just might get more sightings than you'd otherwise expect.
thirdly, if most of the sightings in tasmania are to be believed, then it implies the animals are not THAT uncommon. if thats the case, how come nobody has come accross ANY substantial proof of the animals existance in recent times?
I had a friend who was a large-animal vet in Tas for about 5 or 6 years. I asked him, in that time, how many devils he saw while driving about the country side. On average, he reckoned, roughly one every six months. That's for a species whose *minimum* population size was estimated at 25,000 individuals at that time (having just crashed from 125,000). If the thylacine exists in numbers of about 1,000 individuals, that would mean, on average, he might expect to see one once every 12.5 years. Tigerman's book suggests a current maximum population of about 400 individuals, and over half those in Tasmania's south-west where there are very, very, very few roads. Thylacine's sense of hearing was markedly better than that of dogs' and their sense of smell described as "exceptional". If the thylacine is a shy, retreating creature, you would be very hard pressed to surprise one on foot in Tasmania's south west - and even the people who do go there generally stick to tracks and number perhaps in the tens of thousands per year. Some stretches of wilderness in the order of 80km x 20km are estimated to receive about 4 human visitors every 2 years or so.
and lastly, thylacines were extirpated in a relatively short period of time, with relative ease by farmers who feared they would prey on their stock. that to me suggests two things...
a) that the animals lived in close contact with the areas being settled (which was open woodlands that could be cleared easily, not old growth rainforest) and....
There are at least 4 undisputed pre-extinction reports of thylacines from south-west Tas including inland, away from the coast. The last was in 1932, well after the bounty pressure had declined incredibly due to shortage of numbers.
i can't imagine that the early european settlers went off on month-long explorations into the dangerous terrain of the tasmanian wilderness just to protect their sheep. that wouldn't have benifited them and they would never have needed to. instead like all farmers they protected their farmland and surrounding areas. unfortunately for the thylacines. the farmers settled virtually every single patch of their habitat. thus giving them knowhere to escape. thylacines were not distributed throught the entirety of tasmania at all....
Again - they *were* in SW Tas.
and lastly. mainland sighting are in no way credible in my opinion.
Kevin Cameron's photographs of a juvenile thylacine, allegedly from south-west Western Australia in 1985 deserve an explanation, as does the video footage taken by the Doyles in South Australia in 1973, as does the "Charleville" footage taken in Queensland in 1995.
australia may be a damn big continenet with very little people, but once again, most of it is not thylacine habitat.
Except for the thylacine mummy found at Thylacine Hole in the Nullarbor Plain, Western Australia - carbon dated to 3,000+ years, but the discoverer reported a decomposing odur, fly larvae pupal cases and soft eye and tongue tissue. And the thylacine humerus collected from the Kimberly in north-west Western Australia and associated with bones dated to about 180BP (which - on rumour, granted - were lying underneath the thylacine bone).
the areas that are, mostly along the eastern coast, have been colonised for over 200 years now and nobody has ever shot a thylacine (either with a bullet or a camera).
Disagree again. Robert Paddle's book described how the naturalist Cambrian personally sighted the remains of two thylcines - one freshly killed in the Blue Mountains east of Sydney, the other, by deduction, from the Flinders Ranges in SA. Both examinations dated early 1800s.
All of this needs an explanation before mainland survival of the thylacine can be dismissed. As do the first-hand eyewitness accounts of Aboriginal people of the Flinders Ranges region (also in Paddle's book, dating early 1800s again) and another 2 newspaper references to thylacines shot and killed in the Megalong Valley in the Blue Mountains east of Sydney.
on funding a search - parks and wildife have searched for the thylacine, virtually everyone has - and found nothing.
Agreed. Just like the South American short-eared dog disappeared for 20+ years.
likewise, i find it hard to believe this has something to do with protecting the loggers
Except that the Tasmanian police have already been implicated in covering up evidence that two people were killed for voicing their opposition to protecting Tasmania's unique landscape (
WLMD Newswatch - Killed for protecting the Tasmanian tiger? - Where Light Meets Dark (www.wherelightmeetsdark.com)). And I know of two people who have had bricks smashed through their front house windows after claiming to have seen a thylacine.
put it this way, can you imagine how big the news would be if a living "tiger" was found alive? can you imagine how much international interest in tasmania it would provide? should an effective ressurection of the species follow, can you imagine how much tourism would follow?
Can you imagine you are 4th generation forestry worker? Can you imagine you are in a multi-billion dollar industry? Can you imagine at the drop of a hat the source of your industry - which employs tens of thousands of people directly, hence supports their families and provides business to thousands of other small businesses - gets instantly deprived? Think it won't happen? It happened in WA. An invertebrate, known from a single cave in the Kimberly stalled an estimated $10b - $20b mining industry. As you say - can you imagine the international outrage if an iconic species like the thylacine were proved but not protected? Now consider well upwards of 10% of the state's population either directly or indirectly depends on forestry and mining industries in Tasmania.
i personally don't believe, neither the tasmanian, nor australian federal government, would find opposition to pouring millions into thylacine conservation should one be found alive.
You've got to live here. We've wiped out about as many mammal species as the rest of the world combined in the last 400 years!
but naturally, this is one time when i would love, more that anything else, to be proven wrong.
I'd love to see them too
