Tasmanian Wilderness World Heritage Area

Listen first. Wind moves through the buttongrass, a soft dry hiss across the open moor. Somewhere below, water runs over stone, dark as strong tea. The air smells of wet moss, peat and cold eucalyptus. Clouds slide across the peaks faster than you expect. Within an hour, the light can shift from silver to gold to grey. This is the Tasmanian Wilderness, and it changes its mood the way other places change the hour.

What you are standing in is not a single park. It is a vast patchwork of national parks and reserves, joined together under one World Heritage listing. Together they cover close to a fifth of the island of Tasmania. Cradle Mountain and Lake Saint Clair sit inside it. So do the Walls of Jerusalem, the Franklin and Gordon rivers, and the remote Southwest. Much of this country has no roads at all. People cross it on foot, by small plane, or by boat.

Here is the first surprise. Most World Heritage Sites qualify under one or two criteria. This one meets seven of the ten. That puts it among a very small group of places on Earth. It is listed for its landscapes, its ecosystems and its rare species. And it is also listed for its human story. Very few wild places carry both kinds of value at once.

That human story is very old. Aboriginal Tasmanians lived in these valleys during the last Ice Age. At that time, the island was joined to mainland Australia, and glaciers covered the high peaks. In limestone caves along the rivers of the southwest, archaeologists have found stone tools and the bones of animals people hunted and cooked. These are among the southernmost traces of human life anywhere in the Ice Age world. The palawa people, as many Aboriginal Tasmanians call themselves today, still hold deep ties to this country.

Now look at the trees around you. Many of them belong to a family tree far older than Australia itself. Long ago, Tasmania was part of Gondwana, a giant southern supercontinent that also held South America, Antarctica and New Zealand. When Gondwana broke apart, some of its plants survived here in the cool, wet southwest. Myrtle beech, pencil pine and King Billy pine are living links to that lost world. Botanists come from across the globe to study them.

One tree deserves special attention. The Huon pine grows along the riverbanks, very slowly, sometimes less than a millimetre a year. Some living Huon pines are thought to be more than two thousand years old. Their timber is pale gold, full of a natural oil, and almost impossible to rot. Nineteenth-century piners rowed up these rivers to cut it for boats. Today it is protected, and old fallen logs are prized by woodworkers.

Here is the second surprise. Australia has almost no native trees that drop their leaves in winter. The exception lives here. It is the deciduous beech, which locals call fagus. Each autumn, usually around late April and May, its small crinkled leaves turn gold, then orange, then red. Whole mountainsides glow for a few weeks. Tasmanians make special trips into the highlands just to walk among it. If you are here in autumn, look up the slopes for those patches of colour.

The rivers have their own character. Look closely at the water. In the southwest it often runs the colour of black coffee, or deep amber in the shallows. This is not pollution. Tannins wash out of the peat and the buttongrass, and they stain the water. On a still day, these dark rivers act like mirrors. Rainforest, cliffs and sky appear upside down on the surface with almost perfect clarity.

Those rivers are also why this wilderness still exists. In the early 1980s, the Tasmanian government planned a hydroelectric dam on the Gordon River, below its meeting with the Franklin. The dam would have flooded long stretches of wild river and some of those ancient caves. Thousands of protesters travelled here. Many were arrested at a blockade on the river. The dispute reached the High Court of Australia in 1983, and the dam was stopped. It became one of the defining environmental campaigns in the country's history.

That fight came with memory. A decade earlier, the original Lake Pedder, a glacial lake with a wide pink quartzite beach, had been flooded for hydroelectric power. Its loss shocked many Australians. Some campaigners saw the Franklin as a second chance. Across the world, the green political movement points back to these years as one of its roots. A quiet river in southwest Tasmania helped change how a nation thinks about wild land.

Keep your eyes open for animals, especially at dawn and dusk. Wombats graze in the open grasslands near Cradle Mountain, square and unhurried. Small wallabies called pademelons move through the edges of the forest. In streams, you might see the ripple of a platypus. At night, you may hear the strange growl of a Tasmanian devil. This island is now the last wild stronghold of the devil. The thylacine, the striped Tasmanian tiger, was not so lucky. The last known animal died in a Hobart zoo in 1936.

The weather here deserves respect. Fierce westerly winds known as the Roaring Forties blow in from the Southern Ocean with almost nothing to stop them. Snow can fall in summer on the high plateaus. Rain can arrive with little warning, then clear just as fast. This weather is part of what keeps the place wet, green and wild. Experienced walkers carry warm layers and waterproofs on every trip, even on a bright morning.

Before you move on, pause for a moment. Look at the ground at your feet. A cushion plant, a patch of moss, a single fallen leaf. Then lift your gaze to the farthest ridge you can see. Almost everything between those two points has been shaped by ice, water and time, not by people. As you walk away, listen again for that wind in the buttongrass. It will still be moving here long after you have gone.
