A new study led by Flinders University predicts that the number of endangered Australian bee species will nearly five-fold increase after the devastating wildfires of 2019-20. I am.


In Australia’s 24 million hectares Land area After studying 553 species (about one-third of Australia’s known), researchers say the fauna of bees and the casualties of other insects and invertebrates are clear. Bee seeds) Evaluate long-term environmental damage caused by natural disasters.

“Our research calls for action from governments and policy makers to help these and others immediately. Indigenous people It’s the most endangered. ”

Nine of the bees surveyed were rated vulnerable, multiple fires broke out in the 2019-20 wildfire, about 3,000 homes were destroyed, and an estimated 3 billion animals were killed or evacuated. As a result, two more species were evaluated as endangered.

New research published in Global change biology From North America and Europe to Congo and Asia, wildfires and forest fires are causing repeated damage, devastating biodiversity and suddenly significantly reducing the population of many species. I warn you that there is.

“In these situations, governments and land managers need to respond more quickly to implement priority conservation controls for the most affected species to prevent extinction.” Dray says.

“Protecting insects and other unobtrusive taxa should also be a factor in recovering and preserving some of the hundreds of bees that may not yet be studied or documented.”

He said that the study was conducted on species in Australia and other continents and evaluated other categories not on the dataset or the International Union for Conservation of Nature’s Red List of Threatened Species (IUCN Red List). It states that it will form the basis.

“Climate change is increasing the frequency of Natural disasters Like wildfires affecting our wildlife, “says Dr. Stephen Caddy Retallick, a fellow author at the University of Adelaide and the University of Sydney.

“Our research shows that even if we cannot physically visit the site for research, we can assess the potential impact of natural disasters on under-investigated species.”

“Listing species that have been severely affected under Australian law on the IUCN Red List represents the best approach to encouraging government action,” he says.

“Most people aren’t aware of how vulnerable our native bees are because they haven’t been widely studied,” Flinders University researcher Olivia Davis said in a major treatise. One of the 13 authors. “The fact that Australian honeybees are not listed on the IUCN shows how much these important species are being ignored.”

This study recommends 11 Australian bee species (only 2% of those analyzed) as a priority classification for listing them as threatened species for IUCN. Species and their ecosystems. “

“Ability to collect targeted data is always the gold standard, but data gaps should not prevent us from acting to protect species known to be vulnerable,” Dr. Dray concludes. It is attached.

Collaborative research includes researchers from Flinders University’s Institute for Evolutionary Genetics and Sociality, the South Australian Museum, Adelaide University, Curtin University, Sydney University, Melbourne University, Murdoch University, and Charles Darwin University.
