Wooleen Station pastoralist David Pollock demonstrates the grazing systems used in the arid rangelands regions of Australia are not sustainable. Periodic rest periods for important pasture species have not been adopted due to high competition for grazing from rabbits, wild goats and kangaroos. David argues the best solution to this unmanaged grazing is the dingo, an important apex predator in the ecosystem unhelpfully mischaracterized as a “wild dog” to justify widespread culling programs.
Following the United Nations Global Assessment of Biodiversity and Ecosystem Services report, Professor Brendan Wintle discussed and celebrated the crucial role that ecologists can play (and are playing) in co-designing and implementing solutions to the extinction crisis, in partnership with private land conservation organisations, Indigenous land managers, developers, and governments.
Extreme events are becoming more devastating and more frequent. Communities, economies and ecosystems have increasingly less time to bounce back between them. How do we build resilience for the future? This summer’s devastating bushfires and the disruption of the COVID-19 pandemic have given Australians an alarming insight to the sustained uncertainty we will be facing under a rapidly changing climate. Mike Flattley (Royal Society of Victoria) and Anthony Boxshall (Science Into Action) invited a number of speakers to discuss how we can build resilience into our planning strategies for water, agriculture and biodiversity. Featuring David McKenzie and Claire Flanagan-Smith on the Goulburn Murray Resilience Strategy, Lauren Rickards on Climate Change and Systems Transformation, Brendan Wintle on Decision Making for Biodiversity, Briony Rogers on Preparing the Water Sector for Transition, Richard Eckard on the Transition of the Agricultural Sector, and Sarah Bekessy on Building Community Ownership and Agency in the process.
An iconic species of the Australian Alps, the mountain pygmy possum (Burramys parvus) is found in a unique and fragile habitat that is highly sensitive to environmental change. Habitat conservation and genetic rescue-based conservation efforts have allowed some populations to rebound, but the possum is facing new threats, and the species remains Critically Endangered on the IUCN Red List of Threatened Species. The Bogong moth, a key food source in the mountain pygmy possum diet, has declined in recent years. Efforts to understand Bogong moth biology are underway.
The kingdom of fungi is an important, though often underappreciated, family of organisms which include yeasts, rusts, moulds, smuts, mildews, stinkhorns and mushrooms. Of the vast range of living things on the Earth, fungi make up an impressive 9% of all biodiversity. The immensity of the mighty fungi kingdom and the diversity of fungal organisms and functions means we can’t fit everything into a brief exploration; however, mycologist Dr Sapphire McMullan-Fisher gave us some comprehensive insights to the mysterious world of fungi to share.
