Frog data from the UK Environmental Change Network (ECN) terrestrial sites. These data are collected at ECN's terrestrial sites using a standard protocol. They represent continuous records from 1994 to the present day (ponds are monitored regularly and a record made of the date when spawn are first seen). The data available on the Gateway represent the first day in a year when frog spawn was recorded. Further 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.
