Table 6 Correlation coefficients for correlation between potential covariates for PerMANOVA analyses of vegetation data from McCorkhill and Yackelup forest sites, Western Australia, between 1986 and 2015. Covariates: annual rainfall anomaly for the calendar year for which winter was immediately prior to the time of last fire before measurement (Anom F−1); annual rainfall anomaly for the calendar year of the first winter after the last fire before measurement (Anom F+1); years since fire (YSF); average anomaly for the 10 years prior to measurement (Anom−10); annual rainfall anomaly for the calendar year of the winter prior to measurement (Meas Y−1); and years elapsed (YE)
