Project Description

Southern Australia is expected to experience long sequences of severe rainfall deficits under climate-change models based on IPCC emission scenarios. These droughts, such as occurred from 1997-2009 (the Big Dry), are expected to be punctuated by short periods of above-average rainfall (the Big Wet of 2010-11). We will evaluate the responses of a range of biotic elements (canopy trees, understorey, birds, small mammals, stream invertebrates, fishes and amphibians) in both floodplain and plains landscapes by replicating Big Dry survey programs. We will link these estimates to sequences of droughts and wets derived from regionally downscaled climate models to estimate the relative resilience of these biotic components over the next century.
