説明
The International Butterfly Amateur Network (IBAN) has been providing a framework for national amateur observational groups to capture data about the occurrence of butterflies (Lepidoptera) since 2009. An extensive network of amateur observers use a standard protocol based on Pollard walks to capture this information on paper sheets that they send 1 to their national office. Some of these offices digitize this information into spreadsheets, but others do not have the human resources to do this and they send the paper logs to the IBAN for processing. IBAN produces an annual report based on the sightings provided by these national members, with updated distribution maps and analysis of population trends for some key species.

収集方法
The recommended protocol —Pollard walks— is based on transects that range between 300 and 600 m in length, divided into 50 m sections. Each transect should cover a single habitat type. In each visit, transectwalkers have to count all species of lepidoptera that can be seen within 5 m of the transect line. Special behaviours (egg laying or nectaring), as well as developmental stage (e.g., larvae or eggs), should be recorded as well. There are quality control measures in place: every reported record is flagged "Pending approval". Record status is only changed to "Approved" after verification by a designated taxonomic expert. Species spotted out of their regular season or distribution area are flagged for additional verification. Time of day and weather conditions are recorded at the beginning of the transect. Along the transect, the number of individuals of every species seen is counted. Unidentified species are counted and recorded either by family or as a predefined complex of two or three similar species. Butterflies seen outside the 5 meter range are recorded as “Extra+the number of the nearest section” (e.g. 5-extra). The end time of the transect is also recorded.
| Study Extent | For most countries, these sampling efforts happen once every two weeks from the beginning of October to the end of June. |
