AusPlots Rangelands is implemented across all Australian rangelands jurisdictions (SA, NT, WA, NSW, Qld) in Australia. To date, environmental monitoring throughout the rangelands has been inconsistent. State agencies, universities and other research groups have undertaken many varied projects at different scales to address specific management or research needs. While this work has provided valuable biodiversity data in extensive areas, the geographic coverage is far from complete. TERN Ecosystem Surveillance is now working to identify, prioritise, and fill these data gaps in Australian rangelands environmental monitoring. This work will facilitate ongoing evidence-based decision making capacity at local, regional, national and international levels.
