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


At terrestrial sites during July we continue with evening bat monitoring started in June, but bird surveying is complete. We also survey grazing animals this month, using a dropping count method. At freshwater sites we sample larger invertebrates. Of course, there's also a suite of year-round measurements to be made!
