Notes: See Table 1 for scenario details. Values are landscape-scale means and, for scenarios F1 and F2, mean values over 25 replicated simulations are reported (5th–95th percentile range in parenthesis). Different superscript letters indicate statistical difference between scenarios within the respective time periods at α = 0.05 as determined by Tukey’s honest significant difference method.
