Targeted sampling is considered to be the most efficient way to increase the completeness and length of the fire-scar record, but the accuracy of this method for estimating landscape-scale fire frequency parameters compared with probabilistic (i.e. systematic and random) sampling is poorly understood. In this study we compared metrics of temporal and spatial fire occurrence reconstructed independently from targeted and probabilistic fire-scar sampling to identify potential differences in parameter estimation in south-western ponderosa pine forests. Data were analysed for three case studies spanning a broad geographic range of ponderosa pine ecosystems across the US Southwest at multiple spatial scales: Centennial Forest in northern Arizona (100 ha); Monument Canyon Research Natural Area (RNA) in central New Mexico (256 ha); and Mica Mountain in southern Arizona (2780 ha). We found that the percentage of available samples that recorded individual fire years (i.e. fire-scar synchrony) was correlated strongly between targeted and probabilistic datasets at all three study areas (r = 0.85, 0.96 and 0.91 respectively). These strong positive correlations resulted predictably in similar estimates of commonly used statistical measures of fire frequency and cumulative area burned, including Mean Fire Return Interval (MFI) and Natural Fire Rotation (NFR). Consistent with theoretical expectations, targeted fire-scar sampling resulted in greater overall sampling efficiency and lower rates of sample attrition. Our findings demonstrate that targeted sampling in these systems can produce accurate estimates of landscape-scale fire frequency parameters relative to intensive probabilistic sampling.","pubRank":"1"}],"site":[{"NOAASiteId":"60850","siteName":"Fire Line - IMPD USFRL001","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Arizona","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["32.20759","-110.567"]},"properties":{"southernmostLatitude":"32.20759","northernmostLatitude":"32.20759","westernmostLongitude":"-110.567","easternmostLongitude":"-110.567","minElevationMeters":"2338","maxElevationMeters":"2338"}},"paleoData":[{"dataTableName":"USFRL001","NOAADataTableId":"54797","earliestYear":1463,"mostRecentYear":1868,"timeUnit":"CE","earliestYearBP":487,"mostRecentYearBP":82,"earliestYearCE":1463,"mostRecentYearCE":1868,"coreLengthMeters":null,"dataTableNotes":null,"species":[{"speciesCode":"PIAZ","scientificName":"Pinus arizonica Engelm.","resourceId":"http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:196911-2","commonName":["Arizona pine"]}],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/usfrl001.fhx","urlDescription":"Data - Fire History Exchange File (FHX)","linkText":"Fire Line Fire Scar Data","variables":[{"cvDataType":"FIRE HISTORY|TREE RING","cvWhat":"formation property>event layer>tree demographic and injury and fire event code","cvMaterial":"biological material>tissue>wood","cvError":null,"cvUnit":"dimensionless","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"FHX2 data format; refer to IMPD documentation for description of codes","cvFormat":"Character","cvShortName":"tree_events"},{"cvDataType":"FIRE HISTORY|TREE RING","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"age_ce"}],"NOAAKeywords":["earth science>paleoclimate>fire history>fire scar dates"]},{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/usfrl001-noaa.txt","urlDescription":"Metadata - NOAA Template File","linkText":"Fire Line Fire Scar Metadata","variables":[],"NOAAKeywords":["earth science>paleoclimate>fire history>fire scar dates"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
