We investigated the potential for using camera traps to determine activity indices for commensal rodents living in and around farm buildings, and sought to compare these indices against previously calibrated survey methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>We recorded 41 263 images of 23 species, including Norway rats (<jats:styled-content style=\"fixed-case\"><jats:italic>Rattus norvegicus<\/jats:italic><\/jats:styled-content> Berk.) and house mice (<jats:styled-content style=\"fixed-case\"><jats:italic>Mus musculus<\/jats:italic><\/jats:styled-content> L.). We found a positive correlation between activity indices from camera traps and activity indices from a method (footprint tracking) previously shown to have a linear relationship with population size for Norway rats. Filtering the camera trap data to simulate a 30\u2010s delay between camera trigger events removed 59.9% of data and did not adversely affect the correlation between activity indices from camera traps and footprint tracking. The relationship between activity indices from footprint tracking and Norway rat population size is known from a previous study; from this, we determined the relationship between activity indices from camera traps and population size for Norway rats living in and around farm buildings.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Systematic use of camera traps was used to determine activity indices for Norway rats living in and around farm buildings; the activity indices were positively correlated with those derived from a method previously calibrated against known population size for this species in this context. \u00a9 2017 Crown copyright. <jats:italic>Pest Management Science<\/jats:italic> \u00a9 2017 Society of Chemical Industry<\/jats:p><\/jats:sec>","DOI":"10.1002\/ps.4668","type":"journal-article","created":{"date-parts":[[2017,7,18]],"date-time":"2017-07-18T08:41:46Z","timestamp":1500367306000},"page":"70-77","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Validating activity indices from camera traps for commensal rodents and other wildlife in and around farm buildings"],"prefix":"10.1002","volume":"74","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6037-8601","authenticated-orcid":false,"given":"Mark","family":"Lambert","sequence":"first","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fiona","family":"Bellamy","sequence":"additional","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Budgey","sequence":"additional","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Callaby","sequence":"additional","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Coats","sequence":"additional","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Talling","sequence":"additional","affiliation":[{"name":"National Wildlife Management Centre Animal and Plant Health Agency  Sand Hutton York UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,9,27]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"203","DOI":"10.1071\/WR03120","article-title":"Indexing principles and a widely applicable paradigm for indexing animal populations","volume":"32","author":"Engeman RM","year":"2005","journal-title":"Wildlife Res"},{"key":"e_1_2_7_3_1","volume-title":"Analysis of vertebrate populations","author":"Caughley G","year":"1977"},{"key":"e_1_2_7_4_1","unstructured":"EPPO\/OEPP.
