Site types that use this protocol

Terrestrial

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

MARCH

In March activities at our terrestrial sites pick up after the winter. We start monitoring frog pools, moths and spiders, and prepare for ground beetle recording in April. At freshwater sites the winter measurements continue.
