Animals at risk of extinction in Australia after ‘ecological bomb’ destroys habitats, says report

Animals at risk of extinction in Australia after 'ecological bomb' destroys habitats, says report

Australia has lost more mammal species than any other continent, according to a landmark report released on Tuesday.

The five-yearly environmental study also revealed that the country has one of the worst rates of species decline among the world’s richest countries.

Some animals such as the blue-tailed skink are now only known to exist print captivity, while the central rock-rat and Christmas Island flying fox are among mammals considered most at risk of extinction in the next 20 years. This is significantly due to introduce predator species.

Trees are also threatened with extinction – the sandalwood species is currently in decline.

The report, which follows a period of drought, bushfires and floods ravaging Australiasays that the last five years have caused havoc in the natural environment.

Impacts include increasing temperatures, changing fire and rainfall trends, rising sea levels and ocean acidification.

“The State of the Environment Report is a shocking document – it tells a story of crisis and decline in Australia’s environment,” Environment Minister Tanya Plibersek said in a statement, adding that the new Labor government would make the environment a priority.

New national parks and protected marine areas will be created, she said, to meet a target to protect 30 per cent of Australia’s land and ocean waters by 2030.

The number of species added to the list of threatened species, or in a higher category of risk, grew on average by 8 per cent from the previous report in 2016. 533 animals and 1,385 plant species are now listed.

More than half of those are assessed as endangered or critically endangered on the IUCN red list.

The numbers rose sharply as a result of the bushfires that hit in 2019-2020.

When was the ‘Black Summer’?

The ‘Black Summer’ bushfires killed or displaced an estimated 1 billion to 3 billion animals and razed 9 per cent of koala habitat.

“Those bushfires were an ecological bomb ripping through southeastern Australia,” Plibersek said in a speech at the National Press Club in Canberra.

Spending of around A$1.7 billion (€1.1 billion) a year is required to revive the threatened species, the report said. The new government has committed to spend A$250 million (€168 million) overall.

The environmental report card paints a dire picture of “poor” and “deteriorating” conditions.

Australia’s average land temperatures have increased by 1.4 degrees C since the early 20th century.

“Sea levels continue to rise faster than the global average and threaten coastal communities,” the report said.

Many of the country’s most prized institutions, such as the Great Barrier Reef which has been hit by mass coral bleachingare threatened by climate change and environmental extremes, it said.

What are marine heatwaves?

While coral reef health is declining due to marine heatwaves, the report also highlights the threat of ocean acidification, caused by absorption of carbon dioxide from the air.

This is nearing a tipping point, say the experts. The decline of young coral, which is key to reef recovery, is a growing concern.

Warming oceans have hit kelp beds off the southeast coast, hurting the abalone (marine snails) and lobster industries, Plibersek said.

This should be a wake-up call for the government

Scientists and environmental groups said the report was a wake-up call for the government to step up carbon emissions reductions to curb climate change, overhaul laws to protect habitats and invest more money to protect species.

“There is no more time to waste,” said Jim Radford, a research fellow at La Trobe University, Melbourne.

Plibersek promised that the government would develop new environmental legislation for 2023 after studying recommendations made by an independent review.

There have been calls by Australia’s Green politicians to include a climate trigger in the legislation, which could apply when new coal mines or gas projects come up for approval. However, Plibersek said there were other laws to deal with climate change.

Keen to protect votes in coal mining regions, the Labor party has said every new project would be evaluated on its merits.

But Plibersek said “no” when asked whether the fastest way to cut carbon emissions was to block new coal mines.
