Picture 1: Experimental plots for assessing legacy effects of an extreme wet year (taken in May 2023). The closest plot (bottom right corner) shows extra leaf litter leftover from increased biomass from a simulated extreme wet growing season in 2022. Other plots in the background with metal borders were watered in 2023 to simulate an extreme wet growing season – and we can use the combinations of previous and current extreme wet years to find evidence of legacy effects.
