Australia the driest inhabited continent on Earth receives low rainfall across 70% of its land area Australians refer to this area as a remote region The first people to arrive in Australia came over 60 000 years ago and developed a profound spiritual connection to the land The remote region is a land of extreme hardship and relentless thirst Yet the natural world still thrives in this place This video tells the story of wild plants and animals thriving in a landscape and environment unlike any other place on Earth Australia's wild landscapes including the rugged peaks of the Flinders Ranges were pushed upward 500 million years ago through tectonic processes Daytime temperatures here can exceed 40 degrees Celsius plunging below freezing point as the dark dreary night falls Very few organisms can withstand such extreme climatic conditions and environments The Yellowfoot Rockwallaby a little-known member of the kangaroo family They survive by gathering the meager leaves found on these slopes In winter they work nonstop throughout the day They often sunbathe on cool mornings and rock wallabies are remarkably agile creatures They live in large groups led by a dominant male who has the exclusive right to mate with all the females They show their affection by wagging their tails After leaving their mother's pouch young wallabies live independently And no longer in contact with its mother Young wallabies usually forage alone and must stay alert Hunger-driven predators are always lurking nearby The largest carnivorous bird in Australia is the wedge-tailed eagle This eagle species has exceptionally sharp eyesight enabled by muscles that extend the eyeball It can spot prey from great distances They primarily feed on small armored animals However they also consume washed meat from dead animals as part of their diet Its long hook-tipped beak is a remarkable evolution perfectly adapted for swiftly tearing and pulling flesh from prey Furry mammals are also found here foraging for ants and termites among the shrubs It's hard to fully comprehend the vastness of Australia's arid regions 5.4 million square kilometers of territory An area more than 1.5 times the size of India Yet only 2% of the population lives here Simpson Desert This is where the longest parallel sand dunes on the desert plateau can be found Some sand dunes stretch uninterrupted for over 200 kilometers Trapped by vegetation only the dune peaks were exposed by the wind A black beetle crawls through the swirling sandstorms It lost the ability to fly The wing covers have now fused with its body sealing its shell to prevent water loss At night it searches for and feeds on decaying plants But now the daytime sun is scorching Now it must find a shelter to escape the desert heat Between the sand dunes lie grassy plains a corridor for migratory species A family of emus is foraging for food They stand up to two meters tall and are the largest birds in Australia Well adapted to dry conditions Its inner feather layer allows airflow to pass through and provide cooling Outer feathers help shield against sunlight To protect their eyes during dust storms Amos has a transparent third eyelid It moves horizontally across the eye This bird species can survive for several days without food or water Even in the desert dwell those who bring death The brown snake is highly venomous and considered one of the most dangerous snake species in the world Even the young of this species possess venom capable of killing a human The primary diet of the brown snake consists of small rodents They hunt their prey using a deadly forked net With sharp vision they quickly detect the movement of their prey But they are not without enemies The great horned owl is the natural predator of the brown king snake The brown coloration of the king snake provides it with effective camouflage against desert predators Vegetation in the driest regions is primarily limited to small shrubs Yet one rare species has defied this rule—the wadi tree It resembles a pine tree with needle-like leaves having survived and thrived since ancient times The wadi tree grows extremely slowly By the time they reach 30 years old they've only grown to slightly over 4 meters tall Mature trees can live as long as 600 years Over time their leaves will gradually elongate to help the plant better adapt to its environment and reduce water loss As one of Australia's distinctive landscapes the wadi also serves as a vital habitat for desert bird species Rising dramatically from the arid heart of Australia Uluru is a towering sandstone monolith This area holds sacred significance for Australia's first inhabitants Since the onset of European colonial expansion over 3 000 species have been introduced to Australia significantly impacting the local ecosystem Wild camels are perfectly adapted to the dry scorching conditions of Australia Sent to central Australia to serve as a transport vehicle As mechanization advanced many camels were released into the wild where they adapted to their environment and thrived Australia has the largest population of wild dromedary camels in the world estimated at around 1 to 2 million Wild camels are depleting the scarce water supply and damaging the fragile ecosystem of the Cape Lake region The Uluru region receives an average of 300mm of rainfall per year When rain falls on Uluru it creates a truly remarkable sight Following that the desert rains were soon painted with hues of wildflowers This is Paraquya It spends most of its life as a seed or a small plant But Paraguay has a clever survival strategy After the rain it quickly absorbed water into its plump leaves swelling into a large green mass and sustaining it through the long dry months ahead Sturt's desert pea is found throughout central Australia It appears and persists for only a brief period Within a few weeks its flowers turn into seeds that drift on the wind spreading far and wide before settling into the soil Stay there for many years waiting for the next desert storms The McDonnell Ranges formed over 300 million years ago The vast canyons have been intricately carved by the passage of time Beneath the surface lie cold lakes and oases a paradise for wildlife On both banks of Dry Creek stand cottonwood trees providing shelter for numerous desert-dwelling species Just like these wild Bushricker parrots they're courting each other and preparing for the upcoming breeding season Like all other parrot species Bushrickers require a tree cavity for nesting They will lay between four and six eggs per breeding season The parrot chicks will hatch after about four weeks The Bushrikers have adapted remarkably well to survive in this isolated region They are capable of long-distance flight to locate food and water Heading south is the Finke River It is the oldest river on Earth It flows only a few days each year and its waters never reach the sea instead vanishing into the sands of the Simpson Desert For 350 million years it has shaped the landscape here This valley is home to over 3 000 Livistona mariae palms many of which are several hundred years old Their presence here has long been a mystery Until recently it was believed that its seeds were brought here about 15 000 years ago It was most likely left by the first indigenous people who migrated here Many desert animals avoid the daytime heat and emerge from hiding to forage after dark The Macrotes lagotes a type of ground squirrel was once found on the Tibetan Plateau Their numbers have drastically declined due to being hunted by foxes and wildcats Today only a few remain living in the most remote and arid regions of Australia Its long hairless ears help dissipate heat keeping its body cool With poor eyesight it relies on hearing and smell to locate food Its diet consists of insects seeds and tubers The Macrotes lagotes a rare species of ground squirrel rarely drinks water obtaining all the moisture it needs from its food The vast alluvial plains in western Queensland are known as the Channel Country Its name originates from the water channels flowing through these flooded plains Rainfall in this area is very low In some regions the average annual rainfall is only about 150mm At that time raindrops were typically absorbed by the soil leaving only small patches of standing water Yet sometimes the scenery here also changes When the seasonal rains from the north sweep down they bring major flooding that inundates an area stretching up to 80 kilometers When a large volume of water flows into the Eyre Basin sediment and nutrients will settle back down And across the flooded region dormant seeds lie ready to awaken Within a few weeks the flatlands around Lake Hạng transform completely Low-lying areas transformed into vast wetlands And then as if by magical wonder waterbirds arrived When the fish populations in these river systems reached their peak pelicans were perfectly adapted for long-distance flight They can fly nonstop day and night though not all will survive the journey They stop here to feed before continuing their journey to Lake Eyre where they will reproduce in large numbers One-third of the snail kite species is believed to begin its life in the Eyre Basin These wading birds such as the spoonbill forage for food in shallow waters The swallows gather mud to build their nests Many other bird species also arrive here to exploit the abundant food supply And so as a natural law the water will gradually diminish Those who can fly will depart when this once-lush oasis slowly withers A barren landscape scorching hot and parched with thirst Occasionally erratic rains would fall Yet the plant and animal inhabitants of the snail endured and prevailed They have survived thrived and adapted And they will continue to endure
