We investigated tree mortality driven by lightning strikes in a 40-ha area at the Ngel Nyaki Forest Dynamic Plot, located in south-eastern Nigeria. Ngel Nyaki is a submontane forest with an elevation range of 1,588–1,690m and is part of the Smithsonian's Forest Global Earth Observatory (ForestGEO) network. In every census, we measured and tagged all trees and lianas that have a stem diameter at 1.3 m (or above buttresses) of ≥25 cm and notes were taken about the tree's living status (e.g., broken, hollow) or the trees death mode (e.g., uprooted, standing)." ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "For each tree measured in the forest inventory we installed a custom-made Rogowski Coil sensor, that was designed and tested by the Cardiff Morgan Botti lightning laboratory, to record if a tree was struck by lightning, without damaging the tree or altering the tree's electrical resistance. The Rogowski Coil is a non-contact sensor commonly used to measure alternating and impulse current flowing through the axis of the coil (in our case, down the tree). A quick visual check of the fuse allows us to see if the tree was struck by lightning. In addition to tree stem measurements, in each census, we also took notes on the general state of the coil and fuse, and the electrical conductivity was measured. Trees struck by lightning (e.g. with the fuse blown or melted) were identified at the species level and any lightning-associated damage to the tree (e.g. marks in trunks, broke branches, canopy dieback) and in the surroundings (e.g. canopy gaps, sapling mortality) was documented." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((11.056 6.934, 11.056 6.992, 11.093 6.992, 11.093 6.934, 11.056 6.934))"^^geo:wktLiteral ; ] ; dcterms:temporal [ a dcterms:PeriodOfTime ; dcat:startDate "2018-06-01"^^xsd:date ; dcat:endDate "2021-07-31"^^xsd:date ; ] ; dcat:contactPoint :5237ab05-04bd-44b6-9c53-d21eb2083e39_c0 ; dcterms:publisher ; dcterms:relation ; dcterms:subject "tree mortality", , "forest Inventory", "lightning", ; prov:wasGeneratedBy :5237ab05-04bd-44b6-9c53-d21eb2083e39_fund0 ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2024-02-21"^^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)" ] ; ]; dcterms:creator :5237ab05-04bd-44b6-9c53-d21eb2083e39_a0, :5237ab05-04bd-44b6-9c53-d21eb2083e39_a1, :5237ab05-04bd-44b6-9c53-d21eb2083e39_a2, , :5237ab05-04bd-44b6-9c53-d21eb2083e39_a4, :5237ab05-04bd-44b6-9c53-d21eb2083e39_a5, , ; dcterms:language . :5237ab05-04bd-44b6-9c53-d21eb2083e39_c0 a foaf:Person ; foaf:name "Hill, T." ; foaf:familyName "Hill" ; foaf:givenName "Tim" ; vcard:hasEmail "t.c.hill@exeter.ac.uk" ; foaf:member [foaf:name "University of Exeter"] ; . a foaf:Organization ; foaf:name "NERC EDS Environmental Information Data Centre" ; vcard:hasEmail "info@eidc.ac.uk" ; foaf:member ; . :5237ab05-04bd-44b6-9c53-d21eb2083e39_a0 a foaf:Person ; foaf:name "Stivanello, S." ; foaf:familyName "Stivanello" ; foaf:givenName "S." ; vcard:hasEmail "silvio.stivanello@tin.it" ; foaf:member [foaf:name "University of Exeter"] ; . :5237ab05-04bd-44b6-9c53-d21eb2083e39_a1 a foaf:Person ; foaf:name "Emmanuel, E." ; foaf:familyName "Emmanuel" ; foaf:givenName "E." ; vcard:hasEmail "sonemmy@gmail.com" ; foaf:member [foaf:name "Nigerian Montane Forest Project"] ; . :5237ab05-04bd-44b6-9c53-d21eb2083e39_a2 a foaf:Person ; foaf:name "Abubakar, U." ; foaf:familyName "Abubakar" ; foaf:givenName "U." ; vcard:hasEmail "usmanabubakar105@gmail.com" ; foaf:member [foaf:name "Nigerian Montane Forest Project"] ; . a foaf:Person ; foaf:name "Chapman, H." ; foaf:familyName "Chapman" ; foaf:givenName "H." ; vcard:hasEmail "hazel.chapman@canterbury.ac.nz" ; foaf:member [foaf:name "University of Canterbury"] ; . :5237ab05-04bd-44b6-9c53-d21eb2083e39_a4 a foaf:Person ; foaf:name "Zubairu, M." ; foaf:familyName "Zubairu" ; foaf:givenName "M." ; vcard:hasEmail "misasule2016@gmail.com" ; foaf:member [foaf:name "Nigerian Montane Forest Project"] ; . :5237ab05-04bd-44b6-9c53-d21eb2083e39_a5 a foaf:Person ; foaf:name "Streher, A.S." ; foaf:familyName "Streher" ; foaf:givenName "A.S." ; vcard:hasEmail "annia.streher@gmail.com" ; foaf:member [foaf:name "University of Exeter"] ; . a foaf:Person ; foaf:name "Feldpausch, T." ; foaf:familyName "Feldpausch" ; foaf:givenName "T." ; vcard:hasEmail "T.R.Feldpausch@exeter.ac.uk" ; foaf:member [foaf:name "University of Exeter"] ; . a foaf:Person ; foaf:name "Hill, T." ; foaf:familyName "Hill" ; foaf:givenName "T." ; vcard:hasEmail "t.c.hill@exeter.ac.uk" ; foaf:member [foaf:name "University of Exeter"] ; . a skos:Concept; skos:prefLabel "tree"; rdfs:label "tree" . a skos:Concept; skos:prefLabel "tropical forest"; rdfs:label "tropical forest" . :5237ab05-04bd-44b6-9c53-d21eb2083e39_fund0 a prov:Activity ; .
