Methods
Life forms: orthopterans

Sites: 23

Sampling methods: quadrat,sweep nets

Sample size: 7557 captures or sightings

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)
