Some potential users have indicated that they've had trouble registering with RabbitScan. Apparently the confirmation email has gone astray in some cases and that can be even harder for those on a slow internet connection. Our gurus at Spatial Vision has simplified the registration process, so have another go if you have been frustrated in an earlier attempt. This is a first for the Invasive Animals CRC.

Talk about rabbits and hare questions come up. In fact, so many hare questions have come my way lately that I went to Australia’s hare expert, Dr. Phillip Stott at the University of Adelaide to get some answers. He has kindly passed on the following in response to my inquiries.
Hares are currently regarded as a minor pest, but they do sometimes cause serious damage to LandCare tree plantings and also to new grapevines. However, there have been plagues of hares in Australia in years gone by, and because we don’t understand the ecology of hares very well, they can be regarded as a “sleeper” species – a widespread species that doesn’t currently cause much of a problem, but has a history of causing trouble in Australia and elsewhere.

Induction of a new employee into our feral animal office unveiled her surprising lack of an intimate knowledge of the rabbit's coprophagy. Er um, their, er, how should I put it? um, their requirement to eat their own poop. It's like chewing your cud without the need for extra stomachs. I put it this way in an email: A rabbit's number one is wee, Up against some small tree. In a loo, Goes number two. But he has a special ability: Down the mouth goes number three!

Hopefully all Australian readers know that during May 2009 we are trying to get the community to help us map rabbits in Australia. It's easy to do and its healthy. You might talk to the kids about the environment and you'll help researchers and pest animal managers down the track.
Go to RabbitScan.net.au to join in.

The Easter Bilby has become an icon in Australia. Once wide-ranging, the largest of the bandicoots is now extinct through most of its range. It's a strange beast - it kind of looks a bit like it was put together from the left-overs pile late on Day 6 of the Creation. Its nose is remarkably pig-like and it is used a bit like a pig, rooting around its arid environment to find tidbits. The rooting behaviour modifies the landscape quite considerably - when I visited Australian Wildlife Conservancy's Scotia Sanctuary, I was amazed at the amount of land a few bilbies could "plough" in a couple of nights. The rooting behaviour means any leaves and twigs in the area end up in the holes and dew or rain can develop small mulch pockets for fungi to grow or invertebrates to live.

Australian readers should register at www.rabbitscan.net.au and help us map the activities of rabbits during May.
Rabbits are Australia's number 1 vertebrate pest in terms of their impact on the economy, causing over $200,000,000 in damage annually. They stop regeneration of native vegetation in many situations. Some photos of rabbit damage are included under 'biodiversity impacts" in the gallery here. In the National Park in which those pictures were taken, rangers are spending over $300,000 annually trying to control rabbits, unfortunately with little success.
In the century and a half since their introduction, European rabbits have done untold damage to the Australian landscape. The total cost must be in the hundreds of billions of dollars, but no one could give an accurate figure. The landscape just couldn't cope with them.
There have been several major waves of rabbit control. Myxomatosis in the 1950s, the addition of the rabbit flea in the 1960s to give 'myxo' another vector and calicivirus, or rabbit haemorrhagic disease virus in the 1990s. It appears rabbits are slowly coming back from the knock-down of the 1990s and we are asking Australians to get out there in May and help us map them at RabbitScan. It's a great chance for schools to do a practical exercise where the kids discuss science, environment, history and ethics in one package.
You might not have to get "out there" very far. The accompanying picture was taken at 7.35 this morning as I came into our offices at the University of Canberra.

The Rabbiting On competition has been run and won. Congratulations to the senior winner Barry Hadlow and junior winner Elyse Svanberg on their wonderful stories. Both winners will enjoy taking three members of their families to Australian Wildlife Conservancy's Scotia Wildlife Sanctuary over Easter. Their rabbit story gets them a bilby prize that money can't buy - Scotia is not generally accessible to the public because of its remoteness. They also enjoy a mass of Haigh's Chocolates, including their very famous Easter Bilbies.
Thank you to the hundreds that entered the competition. The stories ranged from hilarious to tragedy and were a delight to read. They were exceptionally difficult to judge. Both winners come from Western Australia, so even my budget consciousness didn't affect decisions.
Barry Hadlow's story on "Old Burt" the trapper mentioned the company Elders Smith as the destination for his bundles of rabbit skins. Elders remains an integral part of Australian agriculture and are sponsors of the next phase of this year's rabbit program: RabbitScan. If you are an Australian reader, we want you to go out an do a "rabbit scan" during May this year. We are using a community mapping approach to map rabbit populations. Even after 150 years in the country, rabbits may slowly be moving into new areas such as the far north. We want to continue to raise awareness of the continuing cost of rabbits and the need to keep them controlled if we are going to allow native vegetation to grow.
Thanks to our other RabbitScan sponsors, Santos and Spatial Vision. Cricket legend Glenn McGrath AM launched RabbitScan at Parliament House Canberra on 4 March 2009. He is pictured here with Woolgrower David Lord of Thackaringa, Broken Hill, Chairman of the Rabbit Management Advisory Group. The stuffed bunnies have been renamed "Brian" and "Mike" after McGrath's most famous "bunnies".

The response to Rabbiting On has been fantastic. The competition only has a few more days to run and then the winners will be announced next week.
If you have a story about rabbits - fictional or not - then get it into the competiton. You could win a trip for four people to Scotia Wildlife Sanctuary in far west NSW. Scotia is owned and run by Australian Wildlife Conservancy and is home to a range of rare wildlife that do badly around feral predators. Bilbies are perhaps the best known, but you'll see mala, boodies, woylies, bridled nail-tail wallabies and a stick nest rat's stick nest, if not the rat. Visit Broken Hill on the way and tour some of the famous art galleries.
There are two classes of entrants - Under-18 and 18 and over. Why note encourage a young one to interview a grandparent or just make up a story. But hurry, entries close at the end of February.

I have little reason to follow Rugby League after the demise of the North Sydney Bears. But the sesquicentenary of the introduction of European rabbits to Australia and the "Rabbiting On"competition has had a lot of people ask me about the origin of the name "Rabbitohs" for the South Sydney team.
Despite once being a "rabbitoh" myself, I was a bit embarrassed not to know. Not a South Sydney Rabbitoh. After a very unsuccessful under-7 season, the coach of the Mosman Rovers decided for the under-8s, he'd get the Mums to sew on a Rabbitoh emblem and we became "Slim's Rabbitohs" that year. Naturally Slim was a very large man. Like all Rabbitoh supporters he was passionate. We didn't take that much notice living on the north shore: on our side of the Harbour we had Manly to hate and that exhausted our stocks of passion.
So I've done some research and it seems there are two lines of thought on the Rabbitohs name. The first and most often repeated is that many of the players sold rabbits to earn a few dollars and after skinning on a Saturday morning, often played with blood and fur on their jumpers. Their cry of "rabbitoh" selling their wares was repeated as a put-down by other teams. Often this origin is attributed to the Depression years, but apparently it dates back further.
The second story is that South's playing field - Nathan's cow paddock later turned to Redfern Oval - was so bad the other players would refer to the "rabbit holes" that became "rabbitohs".
I like the first version better. It goes with the hard struggle image of Souths. Whatever the origin, it seems a uniquely Australian name and another way feral animals have seeped into our culture. By the way, Slim's strategy worked: we came third in the under-8s (I still remember that try against Asquith Ds).

I note I'm in good company enjoying the just-published Pasteur's Gambit (see review below http://feral.typepad.com/feral_thoughts/2008/09/pasteurs-gambit.html). Author Stephen Dando-Collins let me know that esteemed scientist Sir Gustav Nossal had relished the story "Frankly," Sir Gustav said, in part, "I had no idea that Pasteur had so much trouble raising the money for the Pasteur Institute. The generally held notion is that the crowned heads of Europe fell all over themselves to pay homage and grant funds - clearly far from the truth! And I only had the vaguest knowledge of the early origins of the Pasteur Institute in and of the potential contributions to the rabbit plague. So from every point of view I am much in your debt and will be sure to highlight your work in appropriate lectures and other talks." These were very much my feelings in reading Dando-Collins' wonderfully researched work.
Stephen Dando-Collins and I are planning to speak about rabbits, Pasteur, viruses, $10 million prizes and other things around NSW in about March next year.

Rabbits were present on the First Fleet, but they were domesticated and never became feral. It was on Christmas Day 1859 that a couple of dozen wild European rabbits were off loaded from the Brig Lightning, destined for Thomas Austins' property near Geelong. Within a remarkably short time, the descendants of these rabbits were over-running Victoria, South Australia and New South Wales, fast on their way to Queensland and Western Australia. Separate releases meant Tasmania and New Zealand were battling their own rabbit plagues.
Less than half a century later, the colonies were desperate for a solution. Bounties on the rabbits was not working and the problem was growing to the extent that graziers threatened to walk off the land. The colonial governments, dependent on the funds from grazing leases, were nervous. So the Premier of New South Wales, Sir Henry Parkes proposed an international competition, with a prize equivalent to $10 million today, for anyone that could come up with a biological solution.
The Inter-colonial Rabbit Commission formed to judge the 1500 entries was the forerunner of the constitutional conferences that resulted in the formation of the Australian nation.
Author Stephen Dando-Collins has unearthed the extraordinary story of the bid by the world's most famous scientist, Louis Pasteur, to capture the $10 million prize. By 1887, Pasteur had a remarkable history of achievement: he had given birth to the science of microbiology by debunking the theory of spontaneous generation; developed a vaccine for rabies; uncovered the basis of beer and wine fermentation and laid the foundation of modern experimental methods. His legacy, the Pasteur Institute was not yet a reality, with a public subscription falling short of the target to commence building.
Recovering from a stroke brought on by the financial worry of completing his Institute, Pasteur's wife read him an advertisement for the rabbit competition placed by the NSW government. A eureka moment (or a voilà one?) followed as the famed scientist was convinced he had the solution to the plague: fowl cholera. He'd previously worked on the disease and knew it killed rabbits in a matter of hours. He immediately made plans to capture the $10 million prize.
Pasteur’s 24-year-old nephew, Adrien Loir, was his assistant-cum-emissary having worked at his right hand for six years and represented the famed scientist to the Czar of Russia and the beer brewer's of Holland. Loir was sent to test the fowl cholera technique on a rabbit-infested enclosure at the Pommery Champagne Estate and following that success was packed off to Sydney at the head of a small team.
What follows is nothing short of extraordinary. Only hours into the trip, Loir finds that his English interpreter is a fraud, speaking less French than Loir had English. This is the first of a long series of hurdles put in the way of the young scientist in his quest to win the prize and cement his uncle's legacy. Dando-Collins unfolds political and scientific intrigue, sabotage attempts and much more as the dashing Loir becomes a favourite to the colony's social elite. The legendary French actress Sarah Bernhardt even plays a part as she takes him under her wing (and more...) during the Sydney season of her world tour.
Stephen Dando-Collins last book was Bligh's Other Mutiny in which he told the story of Bligh's lesser-known second mutiny, losing the Governorship of New South Wales, effectively leaving the colony a republic for two years. That book combined excellent research and a tale that made it hard to put down. Pasteur's Gambit is told at an equivalent pace so I found myself thinking "just one more chapter before bed". Dando-Collins does an excellent job of describing the science and the historical context without ever becoming tedious and the book is certainly not just for scientists or people interested in the rabbit story. The purists may pick up that the author transposes viruses and bacteria a few times and - heaven forbid - refers once to the rabbit as a rodent (it is of course a lagomorph).
Pasteur's Gambit is a fantastic story made better by the fact that it is true. Dando-Collins has uncovered a story very few people knew anything about, gone on to research rich untapped material, and skillfully laid it out. The result is part science, part history, sprinklings of drama and ultimately a real adventure.

Bilbies ha
ve become an iconic image representing many threatened species in Australia. The long-eared bandicoot used to range over 70% of the country but land clearing, foxes and feral cats have caused a massive reduction in its numbers and range.
The long ears of the bilby and the devastating impact of the European rabbit on Australia no doubt inspired the idea of the Easter Bilby, now promoted by a number of chocolate companies. Rabbit Free Australia http://www.rabbitfreeaustralia.org.au/ own the Registered Trademark and image "Easter Bilby" and they have for years received support from South Australia's Haigh's Chocolates www.haighschocolates.com.au/our_company/environment.html
Darrell Lea chocolates also use the bilby image in Easter chocolate sales and in turn provide substantial donations to the Save the Bilby Fund http://www.dlea.com.au/?Community/Partnership/Save_the_Bilby
However, others use the image without providing any known support to threatened species protection or research. I understand they avoid the
Trademark issue by selling their products as Chocolate Bilbies (within their Easter range by not actually "Easter Bilbies") and by simply being too big for a group like Rabbit Free Australia to take on.
So when you buy your Easter Bilbies this year, check the packaging and make sure you support the companies that support threatened species. You'll feel less guilty eating the chocolate that way.

At one time the European rabbit was by far the worst environmental and agricultural pest in Australia. Biological control in the 1950s and 1990s gave the country massive relief. In fact, myxomatosis still kills more than 40% of the rabbits born in the country today, some 57 years after its release.
Rabbit haemorrhagic disease (RHD, formerly called rabbit calicivirus in Australia) gave further relief in the 1990s. The 2001 State of the Environment report noted its importance in restoration of vegetation and there is no doubt had a better starting point for the drought that is still affecting much of the country. These two examples are effectively the only big wins in vertebrate pests for biological control, although it is so important in weed and insect management.
There are two reasons to start looking seriously for new biocontrols now. One is that rabbits still cause massive damage to biodiversity when they are in low numbers. it takes very few rabbits to cause serious damage to plants - see the photos by Dr Brian Cooke that I've just posted. Secondly, we know that rabbit numbers are beginning to build again. It is always better to try for a solution to a problem before it is overwhelming you.
