Sampling comments: "Grasshopper density was estimated using hoop sampling... Four transects were randomly chosen at each site (at least 100 m from the border, to minimize edge effects)... Each transect contained ten 0.25 m2 hoops 2.5 m apart... Hoops were sampled once per month May–October 1999 and 2000" (3 sites x 4 transects x 10 hoops = 120 hoops; 6 months x 2 years x presumably 1 day per event = 12 days)
