Monitoring, data and research to understand environmental change
We are the UK's long-term environmental monitoring and research programme. For over 20 years we have made regular measurements of air, soil, water and a range of animals and plants across a network of sites to determine how and why the natural environment is changing.
Understanding environmental change. Supporting environmental science
Our data are used to detect and understand trends in the environment and in the presence and abundance of plants and animals. We support researchers by providing long-term environmental datasets and well-instrumented sites for field research.
Science to support policymaking and management of natural resources
ECN’s data and expertise are relevant to a range of environmental policy issues including climate change, pollution and biodiversity loss. Long-term monitoring can inform policies and check how well they work.
An active consortium with links across the globe
ECN is a partnership of UK organisations responsible for environmental policies and natural resource management. We also work with similar networks in other countries. ECN is the UK node of ILTER, the International Long-Term Ecological Research Network.
Why ECN-supported research matters
ECN monitoring and associated research is relevant to a range of environmental and societal issues. For selected publications featured on our website, our Why it matters features provide simple explanations of the research, the main findings and their relevance to people. Image slideshows support each short article.
