The ECN butterflies protocol (IB)


Protocol file


Site types that use this protocol


Butterflies are one of the easier insect groups to identify and monitor and are known to respond rapidly to changes in vegetation abundance and quality.  The Protocol adopted by ECN is that already in use for the national Butterfly Monitoring Scheme, operated jointly by the Centre for Ecology & Hydrology and the Joint Nature Conservation Committee and organised by the Biological Records Centre. This existing scheme provides a strong background of information for comparison with ECN data.

Weekly monitoring along transects is conducted, based on UK Butterfly Monitoring Scheme methodology.


Our field activities


Now that autumn has arrived the ECN fieldwork calendar begins to quieten down. We cease monitoring most terrestrial invertebrates apart from spiders. In rivers and lakes we make the last freshwater invertebrate survey of the year.
