Welcome to the Top 10 Most Endangered Animals in Australia. Jump right in!
Many of the animals in Australia cannot be found anywhere else on the planet, which is why it is especially alarming that so many are risking extinction. Therefore we have compiled a list of the most endangered animals in Australia for you to learn more about them before it’s too late.
Isolated Biodiversity
The populations and diversity of animals in Australia are vast. There’s a reason why the saying goes, “Ah, Australian animals. If it isn’t venomous, carnivorous, or has foot-long claws, it’s probably just a tourist”. With the growing human population and the negative impact of human activities on the environment and nature, the number of animals is reducing rapidly. Most animals are entirely extinct, while others are critically endangered and must be cared for urgently. Unfortunately, the most iconic animal in Australia, the Koala, is also included on the endangered animal list. Let’s learn more about the endangered species of the country that is also a whole continent at the same time – Australia.
Endangered Animals in Australia:
Endangered animals are those whose population is drastically reducing worldwide and nearing extinction due to various reasons such as habitat loss, hunting, deforestation, etc. Following is the list of 10 the most endangered animals in Australia:
#1 Koala (Phascolarctos cinereus)
Koala is an iconic Australian animal native to the country and is the closest living member of wombats. In Australia, koalas are not limited to small regions; they can be seen across various states. They dwell in the open eucalyptus woodland because the leaves of these trees are their ideal food. They have a 60 to 85 cm long body, large fluffy ears, round head, no tail, a stout and spoon-shaped nose, and weigh around 4 to 15 kg. Due to this unique physical appearance, they are easily recognizable. Koalas, Australia’s iconic symbol, face severe threats from droughts, bushfires, and habitat loss. Their population has plummeted from 8 million to just 32,000 in three years. Urgent action, including tree planting, is crucial to prevent their extinction and restore their numbers.
#2 Mountain Pygmy-Possum (Burramys parvus)
The Mountain Pygmy-possum, Australia’s only mammal confined to alpine habitats, faces severe endangerment. Before the 2019-2020 bushfires, it was already at risk due to its reliance on the migratory Bogong moth and specific berries. This small, 11 cm long marsupial with a cream belly and gray fur, hibernates 2-4 meters under snow for up to 7 months. Climate change is disrupting its habitat by shortening winters and reducing snow cover, affecting food availability and hibernation. Currently, only about 2,000 individuals remain, confined to Mt Kosciuszko and southern Victoria.
#3 Silver-Headed Antechinus (Antechinus argentus)
The Silver-headed Antechinus, also known as “suicidal reproducers,” has seen a drastic population decline. In 2013, it was found nesting in the wet eucalypt and rainforests of central Queensland. Fires have devastated these forests, destroying their homes and reducing their food sources. This marsupial, which feeds on beetles, insects, cockroaches, and spiders, inhabits hollow trees in woodlands and rainforests. Currently, only about 2,500 individuals remain. Besides habitat destruction and predation, high testosterone levels cause male antechinuses to die after mating, exacerbating their decline. Conservation efforts are crucial to prevent extinction.
#4 Greater Glider
Greater gliders are giant gliding marsupials native to eastern Australia. They are primarily herbivores and inhabit the eucalypt forests from Queensland, Mossman, to Victoria Daylesford. This animal has a soft tail and ears and prefers traveling in the topmost parts of the thick forests. This is considered a giant gliding possum with a body and a head length of 350 to 450mm. The thick fur on their body makes them appear more extensive than they are. The main reasons for their vulnerability are habitat loss, logging, and bushfires. In the past 20 years, the Greater Glider lost 80% of its total population. Population management and conservation are urgently required to recover and improve their declining population.
#5 Numbat (Myrmecobius fasciatus)
The Numbat also goes by the name Walpurti or noombat. It is diurnal and eats up to 20,000 termites every day. This insectivorous marsupial used to inhabit southern Australia, but now it is confined to a few small colonies in western Australia. These tiny to medium-sized marsupials spend their night in hollow burrows or logs to protect themselves from predators such as foxes and feral cats. Numbats have a 10 to 11cm slender long sticky tongue that allows them to eat ants and other termites. Its long nose also assists it in finding food in logs and on the ground. In Western Australia, it is a faunal emblem. Its primary threats pertain to habitat loss, clearing, and predation. For these reasons, it has become an endangered animal in Australia. Fewer than 800 Numbats exist in western Australia. New populations are being introduced in South Australia and New South Wales to aid conservation.
#6 Smoky Mouse (Pseudomys fumeus)
The smoky mouse, a gray-furred rodent with distinctive gray-pink ears and a long tail, is native to southeastern Australia. It lives in New South Wales, the Grampians, and East Gippsland but is now extinct in the Brindabella and Otway Ranges. Bushfires in 2019-2020, which led to severe smoke inhalation, killed many smoky mice, making them one of the first species affected by smoke. Currently, only about 100 smoky mice remain in southeast forests, facing threats from habitat loss and increased predators. Conservation is crucial as they play a key role in forest health by aiding water penetration and soil aeration.
#7 Woylie (Bettongia penicillata)
The critically endangered Woylie, or brush-tailed bettong, is a small marsupial native to Australia’s shrublands and forests. It features dark fur with a distinctive black brush at the tail’s end and pale gray underparts. Once widespread across 60% of mainland Australia in the 19th century, the Woylie is now restricted to small regions like Tutanning, Dryandra, Greater Kingston, and Peru, with fewer than 2,000 individuals remaining. Habitat loss, predation, competition with rabbits, and disease have driven its decline. Woylies are crucial for forest health, dispersing fungal spores, and their extinction would severely impact their ecosystem.
#8 Long-Footed Potoroo (Potorous longipes)
The Long-footed Potoroo, a small marsupial native to southeastern Australia, is critically endangered, with fewer than 2,000 individuals remaining. This shy species, found between New South Wales and southeast Victoria, and notably in East Gippsland, faces severe threats from logging, habitat destruction, and predation, especially from pigs. The 2019-2020 bushfires devastated up to 82% of its habitat. With a body length of 40 cm and a tail of 32 cm, males weigh around 2.2 kg and females about 1.7 kg. Essential for forest health, they aid in plant recovery by dispersing fungal spores. Conservation efforts focus on reducing forest burning and monitoring logging to help stabilize their population.
#9 Northern Hairy-Nosed Wombat (Lasiorhinus krefftii)
Yomonon is another common name for the northern hairy-nosed wombat, another Australian and critically endangered animal. The Northern Hairy-nosed Wombat, the rarest land mammal in the world, has soft gray fur, a broad muzzle, and long, pointed ears. It grows to about 1.3 meters in length and weighs around 36 kg. Noted for their powerful digging abilities, they have stubby legs and sharp claws. Once found in Queensland, Victoria, and New South Wales, they now exist only in Queensland’s Epping Forest National Park. Their primary threats are wild dogs and habitat loss due to flooding. From a 2003 estimate of 130 individuals, their population has risen to 300 as of 2021, a significant conservation success.
#10 Kangaroo Island Dunnart (Sminthopsis Aitken)
The Kangaroo Island Dunnart is a dark sooty gray rodent with sharp teeth, large ears, and black eyes. Males are larger than females, and they have tails as long as their bodies. Before the 2019-2020 bushfires, their population was around 500, but it has since plummeted to just 50 individuals. This nocturnal animal feeds on invertebrates like spiders, beetles, and ants and lives in the Ravine des Casoars Wilderness Protection Area or Flinders Chase National Park. Main threats include habitat destruction, wildfires, and feral cats. Conservation efforts are ongoing to protect this species and its remaining populations.
Animals Extinction Rate In Australia
The extinction rate of animals and other living organisms is rapidly increasing throughout Australia, which is alarming and requires immediate response and planning to save the animals from becoming wholly removed from the planet. The bushfires in 2019-2020 badly affected up to 3 million animals and reduced their population significantly. The following are a few steps by which we can conserve more living organisms and make the world more environment-friendly:
- Growing native species
- Reducing deforestation
- Banning the hunting of species that are already less in number
- Increasing the number of forests
- Playing a role in keeping the climate appropriate for every species
- Adopting animals
- Learning about endangered species
- Avoid using harmful chemicals
- Avoid destroying the natural territory of wildlife
Last Words
Australia is a land of outbacks, wide open spaces, deserts, beaches, natural wonders, thick forests, and much more. It causes many animals, but with the increasing number of forest fires, human activities, and climate change, most animals are dying in large numbers; hence their population is reducing, and such animals are near extinction. Unique conservation plans are required to protect and increase the population of endangered animals; otherwise, not only will these animals become only part of history, but humans and the natural environment will suffer equally due to the loss of essential actors on our planet.
