Rainfall patterns in Ferlo 1987–2016. a Annual rainfall (trend line back and dashed) is decomposed into core wet-season rainfall (rainfallC; light blue trend line) and early and late rains (rainfallEL; dark blue trend line.) b Temporal trends in the standardised (z-score) variables: above-ground herbaceous (AGH) and woody foliage (WPF), as well as core wet season (rainfallC) and early/late rains (rainfallEL). c Annual herbaceous vegetation production (black dots connected by grey lines) follows a periodic pattern shown as a fitted sinusoidal term (1st harmonic from a Fourier transformation) which is also seen in (d), the wet-season values of VOD (p90), shown as black dots connected by grey lines. Analyses of more long-term datasets are shown in Supplementary Fig. 7. All analyses are based on the nine field sites
