The Mulligans Flat–Goorooyarroo Woodland Experiment, located in the Australian Capital Territory (ACT), is a long-term ecological experiment that has been running since 2005.

Such experiments are needed to inform decision-making. In Australia, there were few experiments running >25 years, and none had replicated plots from different experimental treatments.

The Experiment is a collaboration that began between land managers and research scientists, but has grown to include science communicators, entrepreneurs, and the community.
