a, TAR. b, ERG. c, XLL/XLS. d, MUR. e, URA. f, KNZ. g, HYS. h, CHY. i, SGS. j, SBL/ SBK. The probability density function is based on 37-year historical climate data from 1982 to 2018 for each site (see Methods). Mean precipitation of ambient plots and extreme drought plots during the four-year experiment as well as pre-treatment precipitation are overlaid on the estimated probability density function.
