We quantified and mapped macroplastic (> 5mm) pollution on an Olive Ridley (Lepidochelys olivacea) nesting beach along the Pacific coast of Guatemala by applying both unmanned aerial vehicle (UAV) surveys and ground-based monitoring. We mapped macroplastic items using the OSPAR (Oslo and Paris Convention) beach litter protocol for both UAV imagery and systematic ground-truthing within representative grids. We analyzed plastic abundance with negative binomial mixed-effects models, accounting for sampling method, beach level, and vegetation presence. Ground-truthing revealed a total of 12,297 macroplastic items, corresponding to an average of 2,102 items per 100m shoreline, exceeding the OSPAR beach litter threshold 100 times. Most plastic originated from land-based sources, with accumulation near the high-tide line and within vegetated beach zones- areas that overlap with preferred sea turtle nesting habitat. Ground-based surveys consistently detected substantially higher plastic abundances than UAV imagery, particularly in vegetated areas, where aerial detection was limited. However, the integration of UAVs with ground-truth interpolation facilitated large-scale beach coverage. This study provides the first systematic assessment of macroplastic pollution on Guatemala’s Pacific coast. It highlights both the severity of plastic contamination on a sea turtle nesting beach and the need for pollution monitoring, and it emphasizes the trade-offs between detection accuracy and survey efficiency. Integrating ground surveys with aerial methods offers a scalable approach for identifying pollution hotspots and informing coastal management and conservation strategies in data-poor regions.","keywords":["Earth and Environmental Sciences","Plastic Pollution","Litter","OSPAR","UAV mapping","Beach monitoring","Pacific coast","Seat turtle nesting"],"license":"http://creativecommons.org/publicdomain/zero/1.0","datePublished":"2026-04-15","dateModified":"2026-04-15","includedInDataCatalog":{"@type":"DataCatalog","name":"DataverseNO","url":"https://dataverse.no"},"publisher":{"@type":"Organization","name":"DataverseNO"},"version":"1.0","citeAs":"@data{E8AFE5_2026,author = {Reinhardt, Stefanie and Carbonell Ellgutter, Jennifer Alejandrina},publisher = {DataverseNO},title = {Replication Data for \"High abundance of macroplastic on a sea turtle nesting beach at the Pacific coast of Central America\"},year = {2026},url = {https://doi.org/10.18710/E8AFE5}}","funder":[{"@type":"Organization","name":"University of South-Eastern Norway"}],"spatialCoverage":["Monterrico, Santa Rosa, Guatemala, El Banco"],"citation":[{"@type":"CreativeWork","name":"“Submitted for review\"E"}],"temporalCoverage":["2021-10-01/2021-12-01"],"distribution":[{"@type":"cr:FileObject","@id":"00_ReadMe.txt","name":"00_ReadMe.txt","encodingFormat":"text/plain","md5":"087aa31cef9dae8e57757aabd283f1f3","contentSize":"4047","description":"","contentUrl":"https://dataverse.no/api/access/datafile/:persistentId?persistentId=doi:10.18710/E8AFE5/XO3FUT"},{"@type":"cr:FileObject","@id":"PlasticDataGuatemala2021.csv","name":"PlasticDataGuatemala2021.csv","encodingFormat":"text/comma-separated-values","md5":"ca04b4f2c0623f5d6566fcf8a75345a2","contentSize":"139680","description":"Plastic data from the Pacific Coast of Guatemala","contentUrl":"https://dataverse.no/api/access/datafile/:persistentId?persistentId=doi:10.18710/E8AFE5/KXSFVN"}]}
