IMPROVING the resilience and productivity of sheep in low rainfall farming systems is the focus of a new national farmer-led research project.

The project, shortened to ‘Climate Resilient Sheep Systems’, is being led by Adelaide University and Murdoch University, together with researchers, farmers and industry partners from across the country.

The project’s goal is to develop practical solutions to improve the long-term resilience and sustainability of sheep and their pasture systems under drought conditions.

The farmer-led research will involve at least 26 regional trial sites to be established on operating farms, including eight in South Australia, 10 in Western Australia, and eight in New South Wales.

These sites will be tailored to local conditions in collaboration with local producers and farming systems groups.

Adelaide University project lead Associate Professor William van Wettere said working closely with farmers and farming systems groups ensures the solutions developed are practical, relevant and suited to local environments and regional conditions.

Research sites will include trials at Adelaide University’s Roseworthy Campus and the Muresk Institute near Northam in WA, plus collaboration with ram breeders throughout the country. The trials will identify key traits that are genetically linked to heat tolerance and drought adaptation in sheep. There will also be a comparison of different fodder systems at Roseworthy.

Associate Professor William van Wettere said sheep production remains critical to farming systems and regional communities, particularly in low rainfall zones.

“Sheep enterprises in many low rainfall regions are being increasingly challenged by drought and extreme heat.

“These conditions impact pasture and shrub growth, soil stability and overall feed consistency, which can then impact sheep performance, so we are exploring integrated, long-term solutions.”

The project will investigate climate-resilient sheep genetics for heat and drought resilience characteristics, along with tactics to improve drought-tolerant pastures, shrubs and trees to improve feed availability, grazing landscapes and animal welfare.

“By integrating adapted sheep with more resilient feed base systems, we aim to create more stable and productive farming systems,” Associate Professor van Wettere said.

“This includes improving feed consistency, creating better microclimates for livestock, and supporting overall landscape health.”

The researchers will collect detailed data across both environmental and livestock factors such as soil health, vegetation performance, animal behaviour, heat and drought tolerance and reproductive outcomes.

Murdoch University project lead Professor Andrew Thompson said the project is about understanding the whole system, from soils and plants through to animal performance and genetics.

“By bringing all these elements together, we can identify strategies that farmers can adopt to manage climate change and make real gains in resilience and productivity.

“Projects like this are critical to ensuring Australia’s low rainfall livestock systems continue to be productive into the future.”

The project is funded through the Federal Government’s Long-Term Trials of Drought Resilient Farming Practices Grants and will run until October 2030.
