Data are from a factorial experiment designed to test the effects of small mammals and above- and below-ground invertebrates on plant species richness and composition in native tallgrass prairie (Gibson et al. 1990, https://doi.org/10.1007/BF00318268).

See Gibson et al. (1990) on how data were collected (https://doi.org/10.1007/BF00318268). Data were obtained directly from author. 

File includes metadata, aboveground net primary productivity data, and plant species composition data.
