A total of 830 samples were used to measure fuel moisture content (FMC), and 130 of these were also subjected to calorimetric analysis.  FMC data were obtained gravimetrically by weighing samples before and after drying.  Flammability data were obtained by micro-scale combustion calorimetry, which measures heat release related to flaming combustion of a fuel material.  The flammability metrics recorded were the heat release capacity (HRC), peak heat release rate (PHRR), total heat release (THR), and temperature at maximum rate of decomposition (Tmax).  These data will contribute to the development of models of fuel moisture variability in UK fuels, and thus refine inputs for fire behaviour modelling, which can inform land management strategies in relation to wildfire risk.","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","awardTitle":"Towards a UK Fire Danger Rating System","awardNumber":"NE/T003553/1","orcid":false,"ror":true},{"funderName":"European Union","funderIdentifier":"https://ror.org/019w4f821","awardTitle":"Horizon 2020 Pyrolife Innovative Training Network","awardNumber":"860787","awardURI":"https://doi.org/10.3030/860787","orcid":false,"ror":true}],"hasOnlineServiceAgreement":true,"id":"64d340d7-8f19-49f9-90e0-83d4013e76c2","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/64d340d7-8f19-49f9-90e0-83d4013e76c2.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":"wildfire"},{"value":"fuel moisture"},{"value":"flammability"},{"value":"heathland","uri":"http://www.eionet.europa.eu/gemet/concept/3893"},{"value":"fire","uri":"http://www.eionet.europa.eu/gemet/concept/3212"},{"value":"citizen science","uri":"http://www.eionet.europa.eu/gemet/concept/15358"},{"value":"Calluna vulgaris","uri":"http://www.wikidata.org/entity/Q26615"}],"keywordsTheme":[{"value":"Environmental risk","uri":"http://onto.nerc.ac.uk/CEHMD/topic/5"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Volunteers were requested to collect samples on 19 April 2023, or as close as possible to this date, based on forecasts of dry, fire-prone weather for the UK.  At each sampling location, the approximate height of the heather canopy was measured, and live C. vulgaris was clipped from c. 10 plants along a 20 m transect.  Samples from each transect were combined in an aluminium tin, sealed with tape to prevent moisture loss, and sent for analysis by priority mail.  Samples for fuel moisture analysis only (n = 700) were weighed, dried at 80°C for 48 h, and then reweighed.\n\nSamples for calorimetric analysis (n = 130) were analysed using an FAA Micro Calorimeter (Fire Testing Technology Ltd, East Grinstead, UK).  Two subsamples of 6.2‒31.1 mg were analysed from each sample.  The heating rate of the pyrolysis chamber was set to 3°C s-1, the maximum pyrolysis temperature to 750°C, and the combustion chamber temperature to 900°C.  The N₂ flow rate was set to 80 cm³ min-1 and the O₂ flow rate to 20 cm³ min-1.  For each flammability metric (HRC, PHRR, THR and Tmax) the mean of the tests for the two subsamples was taken.  The remainder of each sample was used to obtain FMC: the sample was weighed, then dried at 50 °C until it reached constant weight.\n\nFuel moisture was defined as: Fuel Moisture = ((wet mass - dry mass) / dry mass) × 100","metadataDate":"2026-06-29T18:29:11","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/64d340d7-8f19-49f9-90e0-83d4013e76c2","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/64d340d7-8f19-49f9-90e0-83d4013e76c2.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"displayName":"Alastair Crawford","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"a.j.crawford2@exeter.ac.uk","fullName":"Alastair Crawford","pointOfContact":"University of Exeter"}],"publicationDate":"2026-03-02T00:00:00.000Z","publishers":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/64d340d7-8f19-49f9-90e0-83d4013e76c2"},{"code":"10.5285/64d340d7-8f19-49f9-90e0-83d4013e76c2","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"displayName":"Alastair Crawford","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"a.j.crawford2@exeter.ac.uk","fullName":"Alastair Crawford","pointOfContact":"University of Exeter"},{"honorificPrefix":"Dr","familyName":"Ivison","givenName":"K.","organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"author","email":"katy_ivison@yahoo.co.uk","fullName":"Ivison, K."},{"honorificPrefix":"Dr","familyName":"Little","givenName":"K.","organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"author","email":"k.e.little@bham.ac.uk","fullName":"Little, K."},{"honorificPrefix":"Professor","familyName":"Belcher","givenName":"C.M.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"author","email":"c.belcher@exeter.ac.uk","fullName":"Belcher, C.M."},{"honorificPrefix":"Dr","familyName":"Crawford","givenName":"A.J.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"author","email":"a.j.crawford2@exeter.ac.uk","fullName":"Crawford, A.J."},{"honorificPrefix":"Dr","familyName":"Davidson","givenName":"S.J.","organisationName":"Université du Québec à Montréal","organisationIdentifier":"https://ror.org/002rjbv21","role":"author","email":"davidson.scott_j@uqam.ca","fullName":"Davidson, S.J."},{"honorificPrefix":"Dr","familyName":"Graham","givenName":"L.J.","organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"author","email":"l.graham@bham.ac.uk","fullName":"Graham, L.J."},{"honorificPrefix":"Professor","familyName":"Kettridge","givenName":"N.","organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"author","email":"n.kettridge@bham.ac.uk","fullName":"Kettridge, N."},{"organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"rightsHolder"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"}],"rightsHolders":[{"organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"temporalExtents":[{"begin":"2023-04-01","end":"2023-05-31"}],"title":"Fuel moisture and micro-scale combustion calorimetry data for Calluna vulgaris across the UK, April-May 2023","topicCategories":[{"value":"biota","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/biota"},{"value":"environment","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/5"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/64d340d7-8f19-49f9-90e0-83d4013e76c2","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
