Weekend at Craggy Peaks

It is 1.15am. I lie in bed, watching the gum trees as they sway menacingly back and forth. The wind roars, gusting up to 48 kms per hour, and now and then the cabin shudders, as if it will rise from its foundations. An hour ago an aluminium chair on the veranda took flight and I wonder if and where we might find it in daylight. Naturally I can’t sleep.


We are at Craggy Peaks, a little over 100 kilometres from home, between the Midlands and the East Coast. The view from our cabin is spectacular; the craggy peaks of Stacks Bluff majestic against a backdrop of bright blue sky.



Our party of thirty is here for the weekend to celebrate 30 years of our HASH group. Some of us have only been a part of this group for less than a decade but we enjoy the camaraderie and the walks. On this special occasion we partake in a delicious three course meal with wine amid the company of old friends and new, an open fire and Haydn’s melodious guitar music.

But prior to this, the day presents us with sunshine and nary a breeze. From our balcony I wave to Steve as he wanders through the bush, camera in hand. Then, from the corner of my eye, I spy a Kelpie racing through the undergrowth and realise, with horror, she is in pursuit of a wallaby. I yell out to Steve who immediately goes to the wallaby's rescue.

After breakfast we begin with a few holes of golf on the course below us. We navigate around the wallaby and wombat poo covered fairways, showing our expertise or otherwise in this fun but frustrating game. Morning tea is served on the veranda of the cabin in which Terry, Steve, Mark and Dick are staying. We bring chairs and mugs and enjoy coffee and fruit buns in the sun.



Then 'Burkie' announces a short (with optional long), flat walk through the bush, after lunch. Of course, the walk isn't short - eight kilometres – and neither is it flat. But it is wonderful to be outdoors on such a beautiful day in this picturesque setting.


First, we hike up and up a narrow rocky track, through thick brush, at times hauling ourselves over fallen trees, until we reach a disused road. Relieved to be at the halfway point, we start out on this alternate way back, only to find that recent rains have flooded the road in sections, forcing us to bypass into the thick and mushy brush at the sides.



Then we reach the creek, previously a dry creek bed - but not today. Some of us attempt to cross downstream via fallen logs, others walk through the water with shoes on, whilst others still remove their shoes and socks, pull their jeans up to their knees, and wade knee-deep over slippery stones through freezing water to the other side.

Drying off as best we can, we venture on, downhill this time. Eventually we see the golf course, and rejoice. But our relief is short-lived as we discover the bridge that crosses this creek is now but a skeleton, with only three planks remaining. Fortunately, Terry, who is little more agile than some, offers his hand and one by one he guides us across.



At last we see our cabins through the tall gums, and exhausted, make a final effort to reach the comfort of a chair and a well-deserved drink.


It is now 2.15am. The wind still howls and the trees still sway and I am disinclined to return to bed. I think I’ll have another cuppa.

Immersed in the Gorge

My article Immersed in the Gorge was published in the September 2019 issue
of the US online magazine 'Write Launch'.


I often visit a special place not far from my home. Here I am revived; here I can observe and here my soul feeds on nature in all its forms. I feel privileged to be able to call this place my own: Cataract Gorge in Launceston, Tasmania.
We owe the discovery of this unique site to explorer William Collins who, in 1804, ‘…observed a large fall of water over rocks, near a quarter of a mile up a strait gully, between perpendicular rocks, about one hundred and fifty feet high; the beauty of the Scene is probably not surpass'd in the world; this great waterfall or cataract is most likely one of the greatest sources of this beautiful river, every part of which abounds with swans, ducks, and other kinds of wildfowl.
At the time Collins was searching for a source of fresh, clean water for the early settlers to use; the gorge then became a vital link in the growth of the new settlement. Prior to this it is thought the aboriginal community was present in the gorge, using the water and perhaps food and shelter, but there remains little archaeological evidence. Some aborigines believe evil spirits occupied the gorge in order to protect their people and future generations, and aboriginal women in particular have felt uncomfortable upon entering the area, believing it may have once been a sacred site for their men.
The history of the gorge dates back hundreds of millions of years, to its volcanic and explosive creation. Deep beneath the first basin is a concentration of fault lines that coalesced millions of years ago to form not one, but three devastating earthquakes, giving rise to its creation. Local geologist Peter Manchester says, ‘You can actually see the cross-section of the movements of the faults on the sides, up near where the suspension bridge is, down the centre of the Gorge.’ These movements and fault lines have not been weathered away, he says, which explains how the current landscape formed.
Down the gorge, the South Esk River winds its way past Jurassic dolerite cliffs to the Tamar Estuary. And the cataract section was probably created some 10,000 years ago, also following a massive earthquake.
So why am I drawn to the Gorge? I am intrigued by its violent past; and the contrast of its serene waters and sheer rocky cliffs is dramatic and breathtakingly beautiful. I also feel a respect for those who walked before me; whose lives were not easy at settlement nor during the eons before. But the Gorge is a mecca for native birds and animals and the chance of seeing its unique inhabitants again brings me here, time and again.
As I wander down through the southern entrance of this 192-hectare site I spy a superb fairy wren on the branch of a shrub. I stop to watch him. His brilliant blue feathers match the cloudless sky with perfection, and he appears unperturbed by my presence as he goes about his daily preening.
I reach the ford at the first basin, where water gathers in slowly before rushing beneath my feet to create a second waterfall on the downhill side. It is here that water birds abound and ducks and ducklings, swans and cygnets are frequent visitors. And I am told that hidden beneath the waters of the basin is an aquatic wonderland of blackfish, long-finned eel, redfin perch and brown trout, to name but a few.
Occasionally an adventurous Australian fur seal makes its way up the Tamar Estuary to sun itself on the cliff face above the Gorge. There it will stay for days at a time, feasting on eel. Today, however, only one lone cormorant perches on a rocky outcrop in the basin, his wings spread full, taking in the sun.
I take the path to the cliff grounds. In 1904 the local mayor noted that, ‘strangers who visit them for the first time are lost in wonder and admiration of the beautiful scenery.’ The same can surely be said even still. I go right and climb even further up through a forest of tree ferns that slope down sharply to the river, hundreds of metres below.
At the top two giant sequoias, Californian Redwoods, guard the entrance to a beautiful dell. One of these trees was planted in memory of prominent early residents William and Isabella Barnes who, in the late 1800s gave this land to the city for the people of Launceston to enjoy.
The dell is a place of shelter and refuge for humans and wildlife, enclosed by oaks and London plane trees, along with gardens of blue, pink, purple and white hydrangeas, and azaleas and rhododendrons that bloom brilliantly in spring. An enormous native olive tree fans its branches out towards the centre of the dell and beyond, amid a copse of bright green tree ferns sits the ancient rotunda, the site of evening entertainments in Victorian times.
To my right a rock wall is submerged in dark green ivy which trails down to meet the grassy floor, partly laid in a carpet of bright green moss. I take a seat on a bench under the canopy of a large birch tree.
Today I am thrilled to see a pademelon nearby, busily foraging. I remain still, hopeful he will stay a while. The Tasmanian pademelon, also called the rufous or red-bellied pademelon, is just one of many mammals to be found within the Gorge, in addition to snails, spiders, frogs, lizards, skinks and even snakes. At other times I have seen wallaby and an occasional echidna, but never the shy nocturnal bandicoot that inhabits these grounds.
Recently I was introduced to the Japanese art of shinrin yoku – or forest bathing. The Japanese believe the benefits of simply walking through a wild or natural area in a relaxed way can induce feelings of calm rejuvenation and increase our flow of energy. Now I relax onto the bench, take a few deep breaths and listen.
To my right I hear the loud ‘whip’ of a Golden Whistler and I follow its flight to the lower branches of the olive tree. On the ground, a common blackbird pecks amongst leaf litter on the floor of the dell, discovers what must surely be a worm and flies off to its nest. I close my eyes and then, in the distance, hear the coo-coo of a dove.
A breeze sighs through the shrubbery and brushes my arms. I take another deep breath and as the scent of the forest envelopes me, I find myself at peace. But my contemplation is broken by a screech. Startled, I look up to see a peacock nestled in the branches of a magnolia tree. Peacocks are the most striking of the gorge birds with their iridescent blue-green feathers and long graceful tails. They were introduced early in the twentieth century as an exotic feature and now, sadly, less than a dozen remain; all males.
A rustling in the bushes reveals a curious peacock who makes his way slowly towards me. He stops a metre or so away and cocks his head, his eyes trained on me. I say hello and he moves closer, pecking at the moss on the ground before me. He seems completely unafraid. At last he wanders away and I see that the pademelon too has left me, so once again I close my eyes.
Now I am aware of the crash of cascading water down at the ford, and imagine it rushing down over the rocks that break the surface at the top of the South Esk River. There it begins its kilometre journey to meet the Tamar Estuary, between those impressive dolerite cliffs.
Eventually, muted voices tell me I am no longer alone. I open my eyes and watch the shadows of overhanging branches dance across the mossy carpet. Then, stretching, I rise and wander over to the olive tree. There, on a leaf, a pair of Harlequin Bugs is joined together in a strange mating dance, their brilliant red and black shells spectacular against the rich green of the leaves.
Following the rocky path from the dell with the river to my right, I cross a narrow bridge to reach a wire-fenced viewing platform overlooking the tranquil gorge. Once, further upstream, a fourth basin existed but decades ago it was dammed to become the Trevallyn Lake. Now, in heavy sustained rains, water released from the dam barrels down the gorge. I can still visualise the rapids from last winter as flurries of white foam spiralled up the cliff faces on both sides whilst masses of spectators looked on, cameras at the ready.
Now the vegetation has changed and here, sparse windswept scrub and trees with exposed roots hang from rocks metres above me. What a contrast to the lushness of the dell. I step around Dog Rock, one of the gorge’s natural rock features and pass a set of hewn stone steps heading up, and a series of shallow caves. I wonder who created them – was it the first settlers or the elusive indigenous peoples. Naturalist John Muir said, ‘In every walk with nature one receives far more than he seeks,’ and I can’t help but think there is so much to this place that I have yet to discover.
Towards the end of the path the majestic Kings Bridge Cottage is perched high above me in the cliff. Built in the 1890s it was home to the gorge’s original gatekeeper. Now there is no gate to keep and the cottage is home to an Artist in Residence program.
From the earliest days of discovery artists and photographers have rendered the gorge in a variety of media. Even in black and white the beauty of the gorge is evident in the proliferation of photographs that date from the 1860s. The cliff grounds, By 1904, were the most popular place to visit in Launceston. Following the introduction of colour photography in 1907, so many photographs were taken here that in 1912 the Town Clerk was forced to decree, ‘…the Council does not permit photographers to canvass for business or sell photographs in the Cliff Grounds.’
In art too, the gorge is immortalised. John Glover, arguably Australia’s most celebrated colonial landscape artist, produced numerous sketches and paintings of the gorge including Tasmanian Gorge, and The Cataract on the South Esk River near Launceston, Van Diemen’s Land. But it is Gladstone Eyre’s watercolour The First Basin that captivates me the most. This atmospheric painting hangs in its heavy gilt frame in the Queen Victoria Art Gallery in Launceston.
In it, a woman sits alone in a rowboat just metres from the rocky shore. The water is dark and in parts rippled, the rowboat reflected in its mirrored surface. From beneath the tree-topped hills beyond, ancient dolerite boulders jut out at odd angles as if having suddenly risen from the basin.
This painting embodies all that I love about this place. Each time I come to the gorge I make new discoveries; changing foliage, other wildlife, unique sounds and smells. And I leave with visions and memories, and the desire to return.
As Marcel Proust said, ‘The real voyage of discovery consists not in seeking new landscapes, but of having new eyes.’

A Day at the Zoo

We spent several enjoyable hours at the Melbourne Zoo last weekend, after finding our way on a city tram to Royal Park.

We first visited the Lion Gorge which also hosts tigers, snow leopards, the Tassie Devil and an interesting animal called a coatis, which is a lot like a lemur but with a pointy nose.



From there we wandered through the Wild Sea with pelicans, seals, and penguins. Then it was on to Growing Wild where we saw the beautiful red pandas and a gorgeous Japanese garden.






The Gorilla Rainforest was next, with tree-top apes and monkeys, lemurs - who roam freely around the human visitors, sunning themselves and showing off - tapirs, followed by the Trail of the Elephants and orang-utans. Finally we visited the giraffe, zebras and baboons.




All of this took so much time that we didn't even see the meerkats, any Aussie animals or the frogs and reptiles - maybe next time.

Zoos Victoria is helping fight extinction, particularly with 21 native threatened species. And the Melbourne Zoo is well laid out with large enclosures and so much greenery visitors really feel they are out in the bush with the animals.

A wonderful experience!

The Biggest Parrot

Everyone knows I love birds; from hens and raptors to parrots and wrens, and everything in between. When we were in New Zealand a couple of years back we were fortunate to see the Kea in the wild, a beautiful colourful parrot-like bird that has real attitude. And we saw the Kakapo, an ancient flightless parrot that still survives today.


Kea


Kakapo

But what we didn't see was the extinct Heracles parrot, the largest parrot in the world. Another flightless parrot, it stood three feet high, weighed about 15 pounds and probably ate meat in addition to fruit and seeds.


Heracles

Heracles was discovered in 2008 when a pair of leg bones were found in a former mining town in New Zealand. But it wasn't until this year that it was identified as a parrot, by comparing the bones to bird skeletons at the South Australian Museum, and to images of birds on the website of the Smithsonian National Museum of Natural History.

There are many extinct species of bird in New Zealand, including the Moa, a giant emu-like bird and its predator the Haast's Eagle. Scientists will now return to the site of the Heracles' discovery, an area rich in fossils from the Miocene period.

Nature's Evolution - using technology

Artist Ginny Ruffner imagines how nature evolves following an environmental apocalypse. And visitors to the museum in Washington DC can download an app that uses augmented reality to show how the evolution takes place.

How nature evolves

'Walk into a first-floor room at the Renwick Gallery of the Smithsonian American Art Museum and the high-ceilinged space looks, at first, quite desolate. Tree stumps made of glass sprout from five rock-like mounds, and at the center of the room, nestled in a sixth craggy habitat, stands a tree made of copper and glass. Otherwise, the landscape seems barren and nearly sapped of color.
But grab one of the red-cased tablets off the wall or unlock a smartphone, and the exhibition springs to life with an augmented reality display. Aim the device’s camera at the tree rings, and inventive flora of the future appear, gently swaying in a virtual breeze. The exquisite world created in the museum's new exhibition 'Reforestation of the Imagination' comes straight from the mind of the Seattle-based artist Ginny Ruffner, who decided to ponder the imponderable—in the aftermath of an apocalyptic mass extinction event, how might life on Earth continue to evolve and thrive?' (taken from the site)

And for those of you who have seen the Dinosaur r'Evolution exhibition at the Tasmanian Museum and Art Gallery in Hobart, you may already have experienced this amazing augmented reality. If you haven't, then be sure to visit it in Launceston at the Queen Victoria Museum at Inveresk.

It is worth a look!!

I took these photos of the augmented reality at the Dinosaur Symposium in Hobart earlier in the year.


The dinosaur is at first just a skeleton


The dinosaur then magically become flesh and wanders around


The developer of the program then has multiple dinosaurs (holograms) all over the stage

Saving the Tasmanian Albatross

Albatross Island, off Cape Grim in the far north-west corner of Tasmania, is both wind-swept and remote, but it is home to some 5,000 Albatross. Living up to 40 years they have a wingspan of up to 2.5 metres and are a beautiful, majestic bird. And although they spend much of their lives at sea, Albatross Island welcomes each couple, which mates for life, every year to breed and raise just one chick.

The marine environment is now changing through increasing sea surface temperatures and acidification, as well as altered wind patterns. The Albatross's prey is decreasing and they are forced to spend more time at sea in search of food.

Unlike other birds, these Albatross cannot just move to another location; they have evolved over the centuries to be in one particular place and cannot adapt to the changing environment. Less than half of their fledglings now survive to return to the island each year and their numbers are declining.

But the Tasmanian CSIRO is attempting to arrest that decline.

Scientists are now attaching miniature monitoring devices to the birds in the hope of gathering data that can help them understand the issues affecting them. And they are building artificial nests that are designed to withstand the rapidly changing Bass Strait weather, and have already seen a 20 per cent higher success rate with fledglings.

These magnificent iconic birds deserve our respect - and we applaud the CSIRO for their action.

Catching up on Wildlife

My plan was to blog weekly but somehow life just seems to get in the way. So, in an effort to get myself back on track here is the latest instalment - with a promise for more regular posts in the future. These are photos of animals and birds I have seen up close in the past six months.















Aren't they wonderful!

Animals of the Middle East - Camel, Falcon and Jellyfish

Camel

The Dromedary, or Arabian Camel, inhabits the Middle East and makes up 94% of the world’s camels. A camel can live for 40 to 50 years and stands 1.85 metres tall at the shoulder and 2.15 metres tall at the hump. It can run up to 65 km/h in short bursts or up to 40 km/h at sustained speed. The camel has long been domesticated and provides milk and meat, and fibre from hair. It is a vital means of transport in the desert.

Interesting Facts

·         The hump of the camel is a reservoir for fatty tissue which helps it to survive in hot climates.
·         It need only drink once every 10 days, even in very hot conditions. When it exhales water vapour is trapped in its nostrils and then reabsorbed into its body, enabling it to conserve water.
·         It is able to withstand changes in body temperature that would kill most other animals. At sunrise it temperature is 34 C and this steadily increases to 40°C by sunset, before it cools off at night.
·         Camel racing is the main racing sport in the United Arab Emirates.

According to Wikipedia, ‘around 700,000 dromedary camels are now feral in Australia, descended from those introduced as a method of transport in the 19th and early 20th centuries. This population is growing about 8% per year. Representatives of the Australian government have culled more than 100,000 of the animals in part because the camels use too much of the limited resources needed by sheep farmers.’




 Falcon

The national bird of the United Arab Emirates (UAE), the falcon is a ‘symbol of force and courage’. It plays an important role in Arab tradition and culture with one-third of the world’s falconers being Arabs.

The falcon is a fast flying hunter that easily takes prey in the air. Adult falcons have thin, tapered wings enabling them to fly at high speed and quickly change direction. The peregrine has been clocked at 290 km/h in a stoop, or dive. And although the falcon strikes its prey with its sharp claws, it generally kills with its beak.

The falcon, like many birds of prey, has exceptional vision with one species measured at 2.6 times that of the average human. The largest falcon is 65cm long, the shortest is 25cm long and the females are bigger than the males. Falcons are distributed across the world, except in Antarctica.

Interesting Facts

·         The falcon is by far the leading ‘pet’ in the UAE.
·         The world’s first falcon hospital opened in Abu Dhabi in 1989.
·         The traditional term for a male falcon is tercel (from the Latin tertius meaning ‘third’) because it is believed that only one in three eggs produce a male bird.



 Jellyfish

The medusae has been in existence for at least 500 million years and was renamed jellyfish in 1796. It is a mainly free-swimming marine animal with a near transparent body, umbrella-shaped bells and trailing tentacles armed with stinging cells used to defend against predators and capture prey. Most species grow quickly and mature within a few months but die soon after breeding.

The jellyfish looks peaceful as it glides gracefully through the water, but at times it will form vast swarms and can be responsible for damaging fishing nets or clogging cooling systems of power and desalination plants. It moves through the water by radially expanding and contracting its body to push water behind it.

The jellyfish is generally carnivorous and feeds on plankton, crustaceans, small fish, fish eggs and larvae, and other jellyfish. It ingests its food and the waste is repelled from its mouth.

Considered a delicacy in some Asian countries, the jellyfish is eaten by humans in other cultures too. It is used in research where the green fluorescent protein produced by some species has been adapted as a fluorescent marker for genes inserted into other cells or organisms.

Interesting Facts

·         There are some jellyfish that are not mobile and are in fact anchored to the seabed by stalks.
·         It is the most energy efficient swimmer of all animals.
·         It is causing problems all over the Middle East due to its growing numbers.
