Table S1. Estimated percentage change (standard error of the mean of all simulations) and statistical power for the current and two-stage models and linear interpolation method, applied to 1000 sets of simulated data for 10 years and 100 sites.
Table S2. Selected species monitored by the UKBMS, with the corresponding number of sites (mean number of sites per year included in the model), model trend (percentage change) in relative abundance derived from both modelling approaches (percentage change of the linear trend of the collated index series) and the start year used for these estimates.
