Habitat: temperate savanna

Protection: wildlife protected area

Substrate: ground surface

Disturbance: grazing

WMT: 29.0

CMT: 1.0

MAP: 572.0

Habitat comments: "a mixed prairie shrubland on undulating sandhills with slopes of 1 to 12%... Sand sagebrush (Artemisia filifolia Torr.) was the principal woody plant.... Pastures were lightly stocked (21-23 AUD ha-1) with cattle annually from April to September"

Life forms: orthopterans

Sites: 24

Site area: 96

Sampling methods: no design,sweep nets

Sample size: 251 individuals

Years: 2000, 2001

Sampling comments: "We selected 24, 4-ha plots... at least 1.6 km apart. Plots were blocked by pasture and randomly assigned fall-burned, spring- burned, or non-burned treatments within blocks, with 4 replications per burn treatment for each of 2 years... Grasshoppers were sampled... at the end of July 2000 and in mid-August 2001. Sampling was conducted by sweeping a standard canvas beating net (38-cm diameter)... Each plot was sampled with 150 sweeps from 3 randomly located 50-sweep transects... Grasshopper abundance across species was greater in 2000 than 2001 at 13 and 8 grasshoppers per 150 sweeps"
abundance per 150 sweeps figure and percentages in table imply that about 250 grasshoppers were sampled, allowing back-computation of counts
