New research has found that habitat loss is a major concern for hundreds of Australian bird species, and south-eastern Australia has been the worst affected.
The Threatened Species Recovery Hub study found that half of all native bird species have each lost almost two-thirds of their natural habitat across Victoria, parts of South Australia and New South Wales.
Where the most bird species are impacted by habitat loss. Grey zones indicate parts of Australia where little habitat loss has occurred. Blue zones have up to 90 species affected by habitat loss, yellow is up to 120 species affected, while the highest category, red, is up to 187 species affected. Image: Conservation Biology.
Lead researcher Dr Jeremy Simmonds from The University of Queensland said the team looked at both threatened and non-threatened birds, including common species.
Parasites are taking a heavy toll on the chicks of Tasmania’s endangered forty-spotted pardalote, but with a helping hand from science these tiny birds can ‘fumigate’ their own nests.
Northern Australia’s mammals have suffered catastrophic declines over the last 30 years. A major new study has found that protecting and recovering habitat by improving fire management and reducing feral cattle, horses and buffaloes is the best approach to address the crisis.
Fire is a complex, important and pervasive ingredient in the ecology of Australia. It destroys life but brings renewal. Professor John Woinarski of Charles Darwin University discusses the catastrophic losses of the 2019–20 fires, and how we can move on from mourning to action that can limit such future devastation.
Clare is a Biodiversity Field Officer with the Australian National University’s Sustainable Farms project. She tells us how she came to this role after an early life on farms in the UK, some bullet-dodging and globe-trotting.
The box gum grassy woodlands once stretched across south-eastern Australia, but have been reduced to less than 5% of their former extent. Holly Vuong speaks with Ann Kristin Raymer and Heather Keith of The Australian National University (ANU) about their new research, part of ANU’s Sustainable Farms, on developing ecosystem accounts for the woodlands to understand why this threatened ecological community is so valuable.
