The ECN spiders protocol (IA)


Protocol file


Site types that use this protocol


Spiders are large diverse predatory taxonomic group with an important ecological role in the UK. The ECN Ground Beetle protocol uses pitfall traps that also efficiently trap spiders. The identification and counting of these spiders therefore represents a cost-effective way of extending the range of invertebrates monitored.

Two-weekly sampling using pitfall traps is conducted.

Our field activities


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.
