We found a similar trend in forb abundance (nearly significant fertilization × herbivore exclusion interaction; χ 2 df=1 = 3.68, P = 0.055; Table S2 , Fig. 4b ); however, forbs were equally abundant in fenced, fertilized, and fenced plus fertilized plots, and did not peak in fertilized grazed plots.
