The following are included: (i) fallen timber found along 100 m transects (species, tree circumference, and whether it was flat on the ground); (ii) trees found inside 10x10-m plots (species; diameter at breast height [DAP]; status [alive vs dead]; and whether the tree was still standing); (iii) plant cover and richness in 2x2 m quadrats (Braun-Blanquet cover and plant species present); (iv) spatial data (GIS layers and buffers around survey and sampling sites); and (v) bird point counts (species detected and distances to each individual recorded) Surveys were conducted at twelve control-impact pairs (24 sites in total), whereby impact sites were those severely affected by Storm Arwen. Within each site, we carried out one 100 m transect, three 10x10 m plots, three 2x2 m quadrats, and two to four bird point counts depending on the size of the site" ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "We investigated the impact of storm Arwen (November-2021) on the forest structure and biodiversity of Kielder (Northumberland, UK) via 100-m transects, 10x10 m plots, 2x2 m quadrats, and bird point counts at twelve paired windblown and control sites (24 sites in total). All our survey site locations were obtained from a handheld GPS device. We counted and measured all fallen trees found along a 100 m transect within each site. We measured the perimeter of each fallen tree three times to allow for volume estimation. Along each transect, we deployed three 10x10-m plots where we counted and measured the diameter at breast height of trees. These plots were placed at 0-10, 50-60, and 90-100 metres along the transect. We visually estimated the cover of grasses, ferns, mosses, fungi, and lichens using the Braun-Blanquet scale inside 2x2 m quadrats at 0-2, 50-52, and 90-92 along our 100 m transects. We also inventoried plant species found within these 2x2 m quadrats. Plants, including trees, were identified using field guides and keys and supported occasionally with photographic-aided identification using the iNaturalist application (https://www.inaturalist.org/observations). For estimating bird richness and abundance, we conducted 2-4 bird point counts within each site between 6 and 10:30 am. During each count, an observer stayed in one spot for 5 minutes and recorded all birds they saw or heard, assigning them to one of five distance categories (0-10 metres; 10-20 metres; 20-30 metres; 30-40 metres; and 40-50 metres). All birds beyond 50 metres were not counted. This was done by either estimating the distance or using a Bushnell Golf Rangefinder. Only those detections that could be identified at the species level were included. All bird point counts were repeated twice to ensure the detection of all species using the survey sites." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((-2.747 55.071, -2.747 55.296, -2.324 55.296, -2.324 55.071, -2.747 55.071))"^^geo:wktLiteral ; ] ; dcterms:temporal [ a dcterms:PeriodOfTime ; dcat:startDate "2022-05-01"^^xsd:date ; dcat:endDate "2022-07-31"^^xsd:date ; ] ; dcat:contactPoint ; dcterms:publisher ; dcterms:subject , , "Bird count", "storm Arwen", "buffer", "diameter at breast height", "forest inventory plot", "GIS", "natural experiment", , "Sitka spruce", , "Norway spruce", "plant quadrat", "windblown", , "National Forest Estate Subcompartments England 2019" ; prov:wasGeneratedBy :9f914e5b-958d-49a8-a5bf-86c35d865257_fund0 ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2023-04-21"^^xsd:date ; dcat:landingPage , ; dcterms:license ; dcterms:accessRights ; dcat:distribution [ dcat:accessURL ; dcterms:license ; dcterms:accessRights ; dcterms:format [ a dcterms:IMT ; rdf:value "Comma-separated values (CSV)" ; rdfs:label "Comma-separated values (CSV)" ] , [ a dcterms:IMT ; rdf:value "Shapefile" ; rdfs:label "Shapefile" ] ; ]; dcterms:creator , , ; dcterms:language . a foaf:Person ; foaf:name "García Díaz, P." ; foaf:familyName "García Díaz" ; foaf:givenName "Pablo" ; vcard:hasEmail "pablo.garciadiaz@abdn.ac.uk" ; foaf:member ; . a foaf:Organization ; foaf:name "NERC EDS Environmental Information Data Centre" ; vcard:hasEmail "info@eidc.ac.uk" ; foaf:member ; . a foaf:Person ; foaf:name "García Díaz, P." ; foaf:familyName "García Díaz" ; foaf:givenName "Pablo" ; vcard:hasEmail "pablo.garciadiaz@abdn.ac.uk" ; foaf:member ; . a foaf:Person ; foaf:name "Powell, P.A." ; foaf:familyName "Powell" ; foaf:givenName "Priscila Ana" ; vcard:hasEmail "priscilaapowell@gmail.com" ; foaf:member [foaf:name "Instituto de Ecología Regional (CONICET-Universidad Nacional de Tucumán)"] ; . a foaf:Person ; foaf:name "Lambin, X." ; foaf:familyName "Lambin" ; foaf:givenName "X." ; vcard:hasEmail "x.lambin@abdn.ac.uk" ; foaf:member ; . a skos:Concept; skos:prefLabel "Kielder"; rdfs:label "Kielder" . a skos:Concept; skos:prefLabel "Northumberland"; rdfs:label "Northumberland" . a skos:Concept; skos:prefLabel "Picea abies"; rdfs:label "Picea abies" . a skos:Concept; skos:prefLabel "Picea sitchensis"; rdfs:label "Picea sitchensis" . a skos:Concept; skos:prefLabel "timber"; rdfs:label "timber" . a foaf:Organization ; foaf:name "University of Aberdeen" . :9f914e5b-958d-49a8-a5bf-86c35d865257_fund0 a prov:Activity ; .
