The Tasmanian Devil in Trouble

Let’s stretch our ‘Australian Week’ by just one more day…

We’ve all heard of the Tasmanian Devil, but surprisingly few people know what they actually look like (I blame a certain popular cartoon character). Even fewer people know that since 2000, the wild Tasmanian Devil population has been affected by a mysterious cancer which is threatening to wipe them out entirely in the years to come.

We love the work done by the Tasmanian Devil Conservation Park, a place I had the privilege to visit in 2010.

Does the Tasmanian Devil deserve its fearsome reputation? We think it does! Have a look at these little devils fighting over their lunch…

You can’t not be drawn to Tasmanian Devil! They’re unique and special and we want more than anything to keep them around.

Here are some quick facts on the disease currently spreading through the the wild Tasmanian Devil population (taken from the small print on the sign pictured below), directly from the Tasmanian Devil Conservation Park.

- The Tasmanian Devil is now an endangered species

- More than half of all wild devils have perished

- Tasmanian Devil Facial Tumour Disease is a unique contagious cancer

- It affects only Tasmanian Devils and is always fatal

-  The cancer is transferred directly by biting during feeding and mating

- Preventing Direct contact is the best way to stop the disease from spreading

- The disease was first noticed in 2000 and has spread across most of Tasmania

- There is no barrier to stop it reaching the west coast

- Its origin is not known

Unfortunately, this mysterious cancer is just one of the many threats faced by Tasmanian Devils. According to IUCN, more than 2,200 are killed each year on Tasmania’s roads.

The Northern Hairy-Nosed Wombat may have a funny name, but it’s plight is deadly serious: it’s one of the rarest large mammals not only in Australia but in the world.

In 2003 the total population consisted of 113 individuals, including only around 30 breeding females.

Their historic range used to extend across 3 states, but they are now found in a tiny 3 km² area within the Epping Forest National Park in Queensland.

This photograph was taken in a museum.

You aren’t allowed to argue with us on this one (although there’s nothing wrong with starting a debate) –The Tawny Frog mouth is Australia’s most charming bird.

It’s a pleasure to introduce you to ‘Kermit’, the friendly Frogmouth at the Tasmanian Devil Conservation Project in Tasmania.

Like so many Australian animals, this sweet little guy is a marsupial, meaning their young are born relatively undeveloped and are raised in a pouch.  Numbats live on a diet of termites, and have a long sticky tongue especially adapted for this.

The Numbat is under threat from habitat loss through land clearing and fire, and are killed by introduced predators such as feral foxes and cats.

It is estimated that there are fewer than 1,000 Numbats alive today.

A Wild ‘Wallaby Safari’… on the Isle of Man?

By Anna Tinker

I wanted to spend the first day of 2012 doing something a little different. So I dressed my parents in khakis, handed them binoculars and piled them into the car for a ‘Wallaby Safari’.  This is not normal.

We live in the middle of the Irish Sea on the Isle of Man. Few people (even those who live here) know about the 100 or so Red-Necked Wallabies we’ve got living wild in the north of our island- all descendents of one legendary pair who escaped from a wildlife park in the early 1970’s.

I’m happy to report that our ‘safari’ was successful. Just as darkness descended and the freezing wind had forced us back to our car, I noticed two large, black figures in the field. Binoculars confirmed them to be a pair of our special Wallabies. Being perhaps the most thrilling of the Island’s wildlife, the sighting certainly made for an exciting start to 2012.

But it got me thinking.

Our wild Wallaby population is steadily growing and their range is thought to be expanding. Our Wallabies are said to inhabit the same ecological niche as hares and they don’t seem to be outcompeting our local hare population for the vegetation they both like to eat. On the surface, it seems they’ve slotted in nicely up in the Curraghs where they’ve taken up home. There’s been little research into the ecological impact of these wallabies on the Isle of Man but for now their presence hasn’t generated much concern.

I’m not sure how to feel about our Wallabies. I know about the massive and devastating consequences that introduced species can bring to an environment. I recently wrote about the impact of the introduced European Fox on Tasmania’s fragile Quoll population. This is one of countless examples.

Entire ecosystems can be and are thrown fatally out of balance by introduced species. Species are often driven to extinction, and rarely does an ‘alien’ introduction fail to leave a threatening impact somewhere in its new environment.

But yet I feel a special affection to ‘my’ wallabies. As long (and only as long) as they aren’t having a negative impact on our indigenous wildlife, the wallabies add a sense of exoticism and excitement to our little island. In this moment in time, I like that I live somewhere where I can go on the occasional ‘wallaby safari’.  Is this selfish? Is it naive?   There is much to learn and explore here, and many questions to be asked.  The treatment of Introduced species will always provoke strong debate, both ecological and emotional.

So I’d like to know…

What are your thoughts about introduced species? Can they ever be ‘okay’? Have you got any stories, examples or opinions you’d like to share?

Meet the Enchanting Eastern Quoll

Eastern Quolls at the Tasmanian Devil Conservation Park, Tasmania, by Anna Tinker

Here’s one of those ‘lesser known’ animals. The sort that you may go your whole life without knowing about.

Which is a pity because the enchanting Eastern Quoll is one of Australia’s smallest and most endearing marsupials. They have lovely little toes, pink button noses and are exceptionally dotty. Now here’s the bit we don’t like: over the last 40 years, it’s become extinct on the Australian mainland and is now found only on the island of Tasmania, where I photographed these little guys.

Traditionally, they’ve been threatened by habitat loss and predators such as feral cats- a huge problem in Australia. It’s thought that they survived in Tasmania because of its lack of dingoes and foxes. But since 2000 and despite conservation efforts, the European Red Fox has been present in Tasmania and poses a huge threat to the state’s unique and precious wildlife, especially its Quolls.

What Can I do?

Do a little research and learn about the often devastating impact that non-indigenous species can have on an environment. Have a look at this website: Parks and Wildlife Service Tasmania. And if you’re lucky enough to visit the unforgettable island of Tasmania, go and drop in on these friendly people and see what fabulous work they’re doing at the Tasmanian Devil Conservation Park.

Not in love yet? Watch this pair of munching marsupials crunch their lunch!

The Eastern Quoll (Dasyurus viverrinus) is extinct in mainland Australia but has a reasonably stable population in Tasmania where it is now listed on the IUCN Red List for Threatened Species as “near threatened

Wollemi Pine: the living dinosaur

Kate

by Kate Booker

In 1994, National Parks & Wildlife Officer David Noble was bushwalking in the Wollemi National Park, some 200km west of Sydney, Australia, when he stumbled across an extraordinary sight: one of the world’s oldest and rarest trees, thought to have gone extinct some 2 million years ago.

Wow!

The oldest fossils of the Wollemi Pine date back some 90 million years, placing it firmly in the age of the dinosaurs, which died out some 65 million years ago.  In fact, Professor Carrick Chambers of Sydney’s Royal Botanic Gardens described it as “the equivalent of finding a small dinosaur on Earth.”

So what does it look like?

in botanic gardens, young Wollemis were originally kept in cages as they were so rare

I’ve seen a few Wollemi now, first in the Botanic Gardens in Sydney, encased in a cage to protect it in the early days before they were more widely propagated and every tree was incredibly precious.  I’ve since seen them in botanic gardens in other countries, where it’s immediately recognizable, and now I know it and recognize it, it feels a bit like bumping into an old friend.

I’m the first to admit I don’t know much about plants and trees, but even to me, it’s an unusual-looking tree, not quite like anything else I’ve ever seen.

At a glance, it’s a fairly unassuming conifer that grows to a majestic 40 metres high with a trunk diameter of over one metre, but look closer and it really is very different from other trees. It has unusual foliage with light apple-green new tips in spring / early summer which become a dark blue-green as it matures.

Mature foliage features two rows of leaves on the branches, not unlike the spines on a Stegosaur’s back and its bark is also very distinctive and has been described as looking very much like bubbling chocolate. (It does!)

There are fewer than 100 mature Wollemi Pines in the wild and the exact location of the few remaining wild trees is a well-guarded secret, but since 2007, they have been available to members of the general public to buy and grow at home, with royalties from sale going to support conservation of both the Wollemi Pine itself as well as other rare and endangered plants.

IUCN Status

The Wollemi Pine (Wollemia nobilis) is on the IUCN Red List of Threatened Species as “critically endangered

Where can I see a Wollemi Pine?

There are now a number of Wollemis in botanic gardens, not just in Australia but around the world, including Canada, the UK, Ireland, Brussels, The Netherlands, Austria, Germany, Japan and Taiwan

What can I do?

Grow your own! As with most endangered species, the greatest threats to the tree’s survival are due to humans: bushfires, the introduction of weeds and plant disease.  The good news is horticulturalists believe one of the best forms of insurance is to grow Wollemi in pots, gardens and parks everywhere!  In addition, royalties from sales of Wollemi Pines will fund ongoing conservation research.

They are available to buy in Australia, the UK, mainland Europe and Japan, click here to order one.
