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.
Professor John Woinarski of Charles Darwin University discusses the importance of averting extinctions of less charismatic animals.
The 2019–20 wildfires have severely impacted animals of all major species groups. Here, national experts on mammals, birds, reptiles, frogs and freshwater fish and crayfish present some of the key challenges for each group and how these will influence management and research priorities in the aftermath of the fires.
Cultural fire management is the way that Indigenous people have used fire to care for Country for thousands of years, and it continues today. The devastation wreaked by the 2019–20 bushfires across millions of hectares was a wake-up call for Australia and the world. Oliver Costello from the Firesticks Alliance explains how the fires demonstrated the need to listen to and care for Country.
Australia has one of the highest rates of plant endemism of any country globally. After the catastrophic fire season of 2019–20, Dr Rachael Gallagher and Professor David Keith are leading two teams to find out which species and ecological communities are most in need of immediate recovery.
The 2019–20 bushfires burnt over 12 million hectares of south-eastern and south-western Australia, causing abrupt losses of biodiversity at a scale never seen before. Over a billion animals were estimated to have died, but the figure is likely much higher. The Australian Government’s Wildlife and Threatened Species Bushfire Recovery Expert Panel is guiding the work of prioritising species and ecological communities for emergency interventions and determining what those actions should be. Hub Deputy Director and Expert Panel member Professor Sarah Legge takes us though the hows and whys of this prioritisation, and some of its challenges.
