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


June is one of ECN's busiest months. In addition to the many other measurements, we start summer bat monitoring at terrestrial sites, and survey for spittle bugs. At freshwater sites, routine water sampling continues and we also sample diatoms this month.
