ECN Freshwater Macro-invertebrates Data

Freshwater Macro-invertebrates data from the UK Environmental Change Network (ECN) freshwater sites. These data are collected by kick sampling (or dredge sampling if kick sampling is not possible) at all of ECN's freshwater sites using a standard protocol. They represent continuous records from 1994 to the present day. The data available on the Gateway are summaries derived from 3x yearly species counts summarised annually. Raw data are available, through a licensing system, from the ECN website - www.ecn.ac.uk.

ECN is the UK's long-term environmental monitoring programme. A wide range of integrated physical, chemical and biological variables which drive and respond to environmental change are collated, quality controlled and made freely available for scientific research. The data also form an important evidence base for UK environmental policy development.

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