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.

Our field activities

AUGUST

At terrestrial sites evening bat monitoring continues and we also sample for spittle bugs using sweep nets. In rivers and lakes we sample aquatic macrophytes (water plants visible to the naked eye). The usual year-round measurements are also made.
