Site types that use this protocol

Terrestrial

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.
