What ECN measures

ECN aims to provide a broad baseline of integrated environmental information applicable to a range of environmental issues (e.g. climate change, water pollution, biodiversity, atmospheric pollution). The measurements made by ECN therefore cover a wide range of physical, chemical and biological 'driving and response' variables. Consistency over time, a vital attribute of any long-term dataset is achieved by adherence to a clearly defined set of published analytical protocols.

While there are numerous long-term, issue-specific environmental monitoring initiatives nationally, ECN's unique multi-disciplinary approach enables the analysis of important relationships between environmental variables and across ecosystem components.

In this section you can read detailed information about the measurements we make and the protocols (methods) used.



In addition to these standard protocols, many ECN sites also carry out additional monitoring, often undertaken as part of other networks or initiatives.


Our field activities


As we head towards winter, biological monitoring at terrestrial sites is scaled down, though we continue to record carabid beetles and spiders. At freshwater sites we make a limited set of measurements from November until February.
