UK Butterfly Monitoring Scheme
uses the transect recording method.

Annual reports are HERE

A TRANSECT is a fixed-route weekly walk, typically 1-3km, lasting 30-90mins.
Volunteers record butterflies in a 5m band in suitable weather in the 26 weeks Apr-Sep, 10.45-15.45.
Transects are often shared.
If weeks are missed, the online programme may estimate values from other counts.
A tailored field-sheet is provided and data is easily entered online.
