Climate and habitat
Habitat: temperate savanna
Altered habitat: pasture

Methods
Life forms: orthopterans
Sites: 12
Sampling methods: no design, sweep nets
Sample size: 461
Years: 2010
Days: 3
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)... Representative numbers of sampling spots for each patch were derived from an area of particular patch (1 spot for 0.5 ha). For every sampling day we recorded 72 sam- pling spots in total... One sampling on a sampling spot comprised series of 10 sweeps... The diameter of the sweep net was 35 cm. The sweep netting was conducted during three visits (23rd of July, 15th of August and 19th of September 2010)"
