Eight sampling reaches were chosen at two sites, Llyn Brianne (4 reaches) and Plynlimon (4 reaches). The experiment consisted of adding deciduous leaves to half of the reaches whilst the other half were maintained as a control (no addition of deciduous leaves). To characterise the benthic organic matter of the studied streams, a Surber net was used to collect monthly samples during 2013 on January (before deciduous leaf addition) and from February to April (after deciduous leaf addition) in each sampling reach. \n\nThe main goal of this survey was to examine how aquatic biodiversity and organic matter stocks respond to leaf addition in moorland and conifer forested rivers. Dr Isabelle Durance was responsible of organising the surveys, Marian Pye was in charge of collecting, processing and sorting the samples. The work was carried out under Diversity in Upland Rivers for Ecosystem Service Sustainability (DURESS) project (Grant reference NERC NE/J014818/1). DURESS was a project funded by the Natural Environment Research Council (NERC) Biodiversity and Ecosystem Service Sustainability (BESS) programme.\n\n","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/J014818/1","awardURI":"https://gtr.ukri.org/projects?ref=NE/J014818/1","orcid":false,"ror":true}],"id":"32eaf811-be10-40cb-9794-7c5a1b97a915","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/32eaf811-be10-40cb-9794-7c5a1b97a915.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Environmental Monitoring Facilities","uri":"http://inspire.ec.europa.eu/theme/ef"}],"keywordsOther":[{"value":"aquatic invertebrates"},{"value":"land use","uri":"http://www.eionet.europa.eu/gemet/concept/4678"},{"value":"ecosystem services","uri":"http://www.eionet.europa.eu/gemet/concept/15138"},{"value":"decomposition","uri":"http://www.eionet.europa.eu/gemet/concept/2014"},{"value":"biological diversity","uri":"http://www.eionet.europa.eu/gemet/concept/15078"},{"value":"invertebrate","uri":"http://www.eionet.europa.eu/gemet/concept/4475"}],"keywordsPlace":[{"value":"Wales","uri":"http://sws.geonames.org/2634895"},{"value":"Plynlimon"},{"value":"Llyn Brianne"}],"licences":[{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Each stream was divided into an upstream control zone and a downstream experimental zone. Samples of benthic organic matter were collected using surber nets. Deciduous leaves were added directly to the stream and by fixing 'Onion bags' of leaves the stream bed and bank. Samples were collected using surber nets on five occasions, January (3-16/01/2013), February (4-7/02/2013), March (11-14/03/2013), April (3-8/04/2013) and May (22-26/05/2013) in all the streams in both the upstream reference zones and downstream experimental zones. Samples were immediately preserved in 70 per cent industrial methylated spirit on-site. In the laboratory, samples were rinsed in tap water over a 350 micrometre sieve, and all macroinvertebrates were separated from debris and preserved in 70 per cent IMS. The remaining material was then rinsed and retained on a 1mm sieve (Endecotts Ltd., UK), dried to constant temperature and weighed to the nearest 0.01gramme. Results were recorded in an Excel spreadsheet. Data was exported to a comma separated value files for ingestion into the Environmental Information Data Centre (EIDC).","metadataDate":"2026-06-29T16:39:45","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/32eaf811-be10-40cb-9794-7c5a1b97a915.zip","name":"Supporting
