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

SEPTEMBER

This is the last of the busy months in terms of field work at terrestrial sites as the season for monitoring butterflies, frogs, grazing animals and bats draws to an end. In rivers and lakes we sample diatoms for the third time in the year. The usual year-round measurements are also made.
