Type of the collection
Monitoring scheme observationsCollection description
Butterflies are monitored using transect walking method. (en)
Päiväperhosia seurataan linjalaskentamenetelmän avulla. Linjalaskennassa havainnoija kävelee vakiona pysyvän reitin toistuvasti, säännöllisin väliajoin kesän alusta loppuun asti. Kullakin kävelykerralla kirjataan lajeittain muistiin kaikki havaitut perhosyksilöt edessä olevalta 5x5x5 metrin alueelta. Reitti pidetään samana myös vuodesta toiseen. (fi)

Butterflies in agricultural landscapesCollection methods
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.Collection quality

The precise location, place names, dates, names of observers and other information may have been obscured or removed. Read more about sensitive observations.
Data may have a research embargo (usually 2–4 years), during which data may have been hidden or obscured as described above. Data producer-owners may have chosen to permanently obfuscate all or part of their data.
