in species diversity Effects of fire and grazing differed among species Powell 2006 Prairie Chickens would likely benefit from managed grazing techniques Benefits to Insects Grasshopper species richness and diversity increased with grazing Joem 2005 Likely due increased heterogeneity of the landscape Negatively responded to average vegelauun height and total plant biomass Soil fertility
