Long-Term Ecosystem Research in Europe

UK Environmental Change Network

ECN logo 

The Environmental Change Network (ECN) is the UK's long-term environmental monitoring programme.  It is designed to collect, store, analyse and interpret long-term data based on a set of key physical, chemical and biological variables which drive and respond to environmental change at a range of terrestrial and freshwater sites across the UK.

ECN was launched in 1992.  Monitoring started formally in 1993 at 8 terrestrial sites and in 1994 at most freshwater sites. A few additional sites were added since then. The data are stored in a central database and are available through a variety of data access methods.

ECN is a multi-agency programme sponsored by a consortium of 14 UK government departments and agencies.  These organisations contribute to the programme through funding either site monitoring and/or network co-ordination activities.

The most recent national network profile (mindmap, biomes, site categories, site number development) is available as PDF here.
