Susannah Hale, a PhD student from Deakin University, spoke to us about the findings of a study on ‘The Effect of Fire and Climate on Small Mammals’. The study started after the 2006 Bushfires and has been running nine years. There were 36 study sites established and each are of 150 square metres. When surveying the sites, baited Elliot traps are used and are checked twice daily, captured animals being tagged, weighed and measured before release. Populations go through a boom and bust phase which are affected by the previous 18 months rainfall and the ‘time since fire’. In the years straight after fire, exotic species predominate. In the first year of the study, 85% of captures were exotics. The house mouse occupies areas quickly after fires and then declines. Four years after fire, 91% of captures were native species.
