Climate and habitat
Habitat: temperate savanna
Altered habitat: pasture

Habitat comments: "grassland... almost completely surrounded by forest"; grazing intensity was low and "meadows were not fertilised" but "were cut once a year using rotary mower without conditioner"
Life forms: orthopterans
Sites: 12
Sampling methods: line transect, pan traps
Sample size: 802
Years: 2010
Days: 60
Nets or traps: 77
Net or trap nights: 4620
Trap spacing: 0.020
Sampling comments: "We selected 12 study patches which differed in management (mowing, grazing or both) and in timing of the treatments... Average size of the individual patches was about 3 ha (the smallest covered the area of 0.6 ha, the largest the area of 6.7 ha)... The pan traps were plastic bowls 15 cm in diameter and 8 cm deep... The pan traps were disposed in transects across all patches; totalling 77 traps. Transects ran from one edge of a particular patch to another, or directly through more patches and their edges together (formed by baulks or belts of trees). The distance between each two traps was approximately 20 m... The samples were collected at approximately ten-day intervals (from 24th of July to 21st of September 2010; 10 collections in total)"
