The population of Koala is declining due to the increasing human impact on nature

Bushfires, housing divisions, vehicle crashes and wall attacks – all of which have hurt koalas – have been devastating in recent decades.

This has led to a decline in the population and an increase in the number of diseases among koalas, according to a new study published Wednesday in the journal Journal. PLOS ONE.
The number of diseased koalas has increased over the last 30 years, while the number of diseased koalas that can be released back into the wild has decreased, Education Said. It analyzed 29 years of value data on koala sightings and zoo visits from three wildlife rescue teams in New South Wales, Australia.

Researchers have found that a combination of environmental impacts and human disturbances on koala habitats, puts many parts of Australia at risk of extinction.

“In the last 10 years, we have seen a significant increase in koala rescue as there are more koalas in the open and on the ground,” said Edward Narayan, a senior professor of animal sciences at the University of Queensland.

That is not a good sign for the species that live in the trees. For their survival, koalas rely on eucalyptus trees, which they use for food but also to find shelter and breeding.

Environmental degradation, rising global temperatures, and droughts have led to the collapse of many cones because the trees have withered leaves and do not have enough water or nutrients. Researcher at the University of Sydney In a separate study.

Narayan says koalas are in danger because in the long run, chronic stress is detrimental to their immune system.

“Humans have all these artificial resistance mechanisms to deal with stress, but with animals, the problem is that most small animals are good at hiding their fears,” Narayan said. “You can not tell whether an animal is sick or not unless it hurts.”

The most common reason koala is reported or accepted in clinical treatment is disease – including signs of infection, Poor physical condition And organ damage data, University of Queensland study data revealed.

“We have also found that cases are on the rise, so more and more koalas have been found to have a high prevalence of cholera, which is one of the diseases that affect koalas,” Narayan told CNN. “As a result, many koalas really need to be improved, but unfortunately.”

Human effects on koalas

Human population growth has had an increasing negative impact on the koala population through multiple stressors, according to Narayan.

“One of the biggest factors is land clearance,” Narayan said. “What is happening is that koalas are facing more and more pressure outside the city. That housing corridor is more vulnerable … we can see these developmental bubbles affecting koalas.”

Narayan added that agriculture also played a role in the decline of koalas, as natural land was set aside for agricultural development. The study’s researchers argued that sustainable farming practices and nature conservation were critical to saving koalas.

Climate change Also contributes to the decline of koalas. For example, drought leaves the koalas very dehydrated and there are healthy cane trees for them to call home.
And Australia experienced recorded wildfires in 2019 and 2020, possibly Exacerbated by climate change, according to Report By New South Wales Bushfire Inquiry. Fires are not uncommon in Australia, but they have become more violent in recent years, exacerbating the effects of the climate crisis.

WWF aims to double the koala figure

The Global Fund for Nature – Australia was launched in early October Ambitious plans Called Regenerate Australia with the aim of increasing the number of koala on the east coast of the country – partly planting seeds to plant a variety of trees that grow koala food.
Researchers say policymakers, farmers and the general public need to focus more on conserving the environment to protect koalas and other Austrian wildlife.

WWF says planting more trees is necessary after the bush season, when 7,000 trees were harvested and 3 billion animals were slaughtered.

“Unprecedented damage calls for an unprecedented response,” Dermot O’Gorman, WWF Australia Executive Director, said in a statement.

O’Gorman added that efforts to increase the number of koalas by 2050 will benefit many other species as well as boost the economy of communities in the region.

“WWF is excited to experiment with specialized drones, some of which can grow up to 40,000 seeds a day, to create corridors so that koalas and other wildlife can move across landscapes divided by fire and land clearing,” he said.

Policy makers, farmers and citizens need to pay more attention Protect the environment – Not only for the health of the koalas, but also for the health of the world and future generations, Narayan said.

“The koalas add to the voice of the Australian environment,” he said, adding that their decline signifies a bigger crisis in the natural world. “The amount of damage that has been done to the planet – we can not hide from it.”

“Ultimately what will happen to this effect on nature is that we will build our own grave, in any way possible,” he said.
