Database of the UK Environmental Change Network

It aims to distinguish man-made changes from natural variations and trends, and to give early warning of undesirable effects. ECN measurements are collected regularly at a growing number of network sites (currently 10 terrestrial and 37 freshwater) throughout the UK, using standardised protocols.

The data cover a wide range of physical, chemical and biological parameters, including climate, air quality and flow, soil development and chemistry, invertebrates, vertebrates, vegetation, land use and site management practice. Oracle and Arc-Info are used to handle the resulting temporal and spatial database, incorporating meta-information on data specifications, origins and quality.
