Syke - Butterflies in Finnish agricultural landscapes

Sampling

Butterflies are recorded from a 5x5 meter area ahead of the observer. The butterfly count is conducted repeatedly during the summer along the same walking route, which is also kept constant from year to year. In Finland the suggested mininum number of annual counts has been seven, conducted once a fortnight from late May to late August. Weekly counts are recommended, and usually done on ca. half of the transects. However, due to our northern location the butterfly season is typically no longer than ca. 16 weeks, and in the northernmost transects less than ten weeks.
