Climate and habitat
Habitat: temperate savanna
Substrate: ground surface
WMT: 29.4
CMT: -17.2
MAP: 378.0
Habitat comments: "mixed grass prairie... The region is semiarid... Nearly all sites were dominated by native vegetation"
MAP 355 to 400
Life forms: orthopterans
Sites: 23
Sampling methods: quadrat, sweep nets
Sample size: 7557
Years: 2001
Seasons: summer
Sampling comments: "23 sites... were located within 35 km of each other... At each site, a 10 m by 10 m subplot was established... Sites were sampled... four times... between the last week of June and the first week of September... A sweep net sample was taken, using an insect aerial net with a four foot handle, in the vegetation surrounding the 10 m by 10 m sampling plot... An equal number of 150 sweeps were taken" (presumably meaning 150 sweeps x 4 sampling events x 23 sites = 13800 sweeps)
