Sweep samples for estimating grasshopper (Acrididae) composition and relative abundance at one site for each of 12 Konza Prairie LTER fire/grazing/soil treatment combinations (3 fire treatments x 2 soils x 2 grazing treatments). Samples were collected in June, August, and September. At each site on each occasion, 18 sets of 10 sweeps each (180 sweeps total) were taken. Stored data include for each site on each occasion: total number of each species (all instars combined) collected and total number for each instar for each species (180 sweeps combined).
