Dataset are structured following well-established data formats Darwing Core. Three files are provided. The first file (ebd-rept_event_20220606) contains the information of the project, the institution and the description each event (time of occurrence, geographical coordinates, habitat type, etc…); the second file (ebd-rept_occ_20220606) contains the information of the occurrences of species recorded in each transect, taxonomic classification, geographoical coordinates of its observation, etc…; and the third file (ebd-rept_measurOrfact_20220606) provide information of the description of other variables measured during counts., 1. ebd-rept_event_20220606: eventID, institutionCode, institutionID, datasetName, continent, country, countryCode, Province, Location, Locality, LocalityID, eventDate, eventTime, decimalLatitude, decimalLongitude, decimalLatitudeEnd, decimalLongitudeEnd, verbatimCoordinate_func, verbatimCoordinate, habitat, sampleSizeValue, sampleSizeUnit, samplingEffort, recordedBy, samplingProtocol.-- 2. ebd-rept_occ_20220606: RecordedBy, eventID, OccurrenceID, OcurrenceTime, decimalLatitude, decimalLongitude, basisOfRecord, individualCount, lifeStage, sex, OccurrenceRemarks, behavior, kingdom, Class, Family, scientificName, genus, specificEpithet, scientificNameAuthorship, taxonRank.-- 3. ebd-rept_measurOrfact_20220606: eventID, measurementID, measurementType, measurementValue, measurementUnit, measurementMethod., The monitoring of the reptile community in Doñana was initiated in 2005 as part of the Monitoring Program of Natural Resources and Processes. The aim was to obtain a temporal and continuous series of data in the abundance of reptile species and analyze the trends to detect changes in their populations. The records are collected annually between 2005-2021 by members of the monitoring team which perform 7 sampling transects in different habitats (dunes and Mediterranean vegetation) three times per year in the periods when reptile activity is high (March-June and September-October), with good environmental conditions (temperature between 17 and 25C and absence of rain). Reptiles species are visually searched along the transects (linear or circular) that are carried out by one person on foot. Length transects are variable, averaged 1858 ± 51.86 meters, where all reptiles detected are recorded in the app Cybertracker. Three transects runs through wooden footpaths (within the Natural Park) and four transects (within the National Park) are placed on sand-trails surrounded by Mediterranean shrublands. The method used records only terrestrial species since it has not been able to detect those species that have a fossorial behaviour (the Mediterranean Worm Lizard Blanus cinereus) or those species that used to be frequently hidden in dense vegetation (the Mediterranean Chamaleon Chamaeleo chamaeleon). Data recorded during the surveys include weather description (cloud cover, temperature, rain, or wind speed), species identification, number of individuals, sex and life stage of the reptiles when possible, as well as time and georeferenced data of the observation. Between 2005-2007 data is registered in Excel file and since 2008 data is recorded in CyberTracker sequence (see protocol). The protocol used has been supervised by herpetological researchers and the data have been validated by the members who performed the transects., We acknowledge financial support from National Parks Autonomous Agency (OAPN) between 2002-2007; Singular Scientific and Technical Infrastructures from the Spanish Science and Innovation Ministry (ICTS-MICINN); Ministry of Agriculture, Livestock, Fisheries and Sustainable Development from the Regional Government of Andalusia (CAGPDES-JA) since 2007; and Doñana Biological Station from the Spanish National Research Council (EBD-CSIC) since all the study period (2005)., Peer reviewed
