UK Environmental Change Network (ECN) spittle bug data: 1993-2012

[THIS DATASET HAS BEEN WITHDRAWN]. Spittle Bug data from the UK Environmental Change Network (ECN) terrestrial sites. These data are collected by quadrat sampling at all of ECN's terrestrial sites using a standard protocol . They represent continuous annual records from 1993 to 2012. Spittle Bug adults (Philaenus spumarius) are sampled and separated by sex and by colour morph; it is likely that the proportions of morphs are environmentally determined and will therefore be good indicators of environmental change. Spittle bug nymphs are counted and the mean number of nymphs per spittle recorded. ECN is the UK's long-term environmental monitoring programme. It 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. These organisations are: Agri-Food and Biosciences Institute, Biotechnology and Biological Sciences Research Council, Cyfoeth Naturiol Cymru - Natural Resources Wales, Defence Science & Technology Laboratory, Department for Environment, Food and Rural Affairs, Environment Agency, Forestry Commission, Llywodraeth Cymru - Welsh Government, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Government and Scottish Natural Heritage.
