Our research focuses on the population dynamics of plants and how they are influenced by impacts of natural disturbances and global environmental change. We are particularly interested in the interactive effects of fire, grazing and drought in grasslands and woodlands in southern Australia, and how climate change, fragmentation and shrub encroachment affect ecosystems.

Science and land management
What's often not understood is that scientists are inherently conservative beasts - before proclaiming "effects" of X on Y, they have tested their ideas through replicated observation and experiment, considered alternative hypotheses, and used statistical inference to interpret their findings. They do this because they want to make sure that they don't proclaim significant effects when none occur - a false positive. This is called a Type 1 error in statistical terms.
