Sampling methods: line transect,butterfly nets,visual
Sample size: 325 captures or sightings
Years: 2015
Seasons: summer
Sampling comments: "we selected 20 plots on used (GMO) and 20 on abandoned hay meadows (GAB)... Half of the GAB sites (n = 10) were located on floodplain grassland"
GMO sites included "mowing tracks, haystacks" and GAB sites did not
"The sample plots were surveyed twice between June 1st and August 2nd, 2015. All butterfly species (incl. Hesperidae) were counted along standardized Pollard Walks of 200 m length... Individuals were caught with hand-held nets or identified with the help of binoculars"
