Key messages from the 'ECN at 20' Special Issue of Ecological Indicators, 2016

A summary of key points made by the 15 papers comprising a journal special issue published to mark 20 years of ECN data from terrestrial sites (Introduction)



The UK Environmental Change Network (ECN) was established in 1992 in response to calls for more long-term, quantitative information about the state of the environment and how and why it was changing. Since then, the network’s terrestrial component has comprised 12 sites ranging from lowland farms and woodlands to upland moors and mountains. Since 1994, ECN has also collated data from a network of lakesrivers and streams.

To mark the 20th anniversary of detailed site-based monitoring, we undertook a series of activities, including a symposium in Lancaster in May 2014, the release of 20-year ECN datasets, available from the CEH Environmental Information Platform, a CEH blog, ‘Behind the scenes at the UK's Environmental Change Network’ and an article in NERC’s Planet Earth magazine: ‘Taking the environment’s pulse’.

We also invited symposium speakers, ECN site managers and other scientists involved in research at specific ECN sites, or analysing ECN data more generally, to submit manuscripts to a special issue of the journal Ecological Indicators, guest edited by Andrew Sier and Don Monteith (Sier, A and Monteith, D. (eds). 2016. Assessing ecosystem resilience through Long Term Ecosystem Research: observations from the first twenty years of the UK Environmental Change Network. Ecological Indicators 68, 1-156.)

The resulting 15 peer reviewed papers in the special issue cover a wide range of topics and demonstrate the broad range of science questions that ECN data are helping to address. These include network-wide summaries of environmental and biological trends over the first two decades of monitoring, more site-specific assessment of the ecological impacts of local pressures resulting from changes in management, biological and ecosystem service indicator development, and the testing of new monitoring technologies.

These 83 key points from the papers provide a useful summary. Links to the papers themselves (on Elsevier's website) are also provided.
