Figure 11

The quartile variation coefficient (QVC), which is a measure of spatial resource concentration, was calculated from spatial model predictions within ~50 km of both Boonah and Canungra roosts and plotted with a 3-month moving average of the Southern Oscillation Index (SOI) from January 2006–December 2015. The QVC values are plotted as the blue line and the SOI values are plotted as the orange line.
