Fieldwork was undertaken in August and September 2022 and in August 2023. The data includes abundance data from established 40 forest plots, each 20 m × 100 m, with 5 to 13 plots per management area to quantify the ecological health of each site. In each plot, all individuals of M. flexuosa ≥0.4 m tall were counted and classified into three size classes: short saplings (0.4-1.49 m total height), tall saplings (≥1.5 m total height and without stem or with stem height <1.3 m), and pole stems (≥4 m total height and with stem height ≥1.3 m). For each pole stem, life stage as juvenile (<15 m total height), subadult (≥15 m total height without flowers or fruits), or male/female adult (≥15 m total height with inflorescences or infructescences) was recorded. Sex, the number of racemes with fruits for each female adult individual, and peat thickness were also measured. In this dataset, M. flexuosa populations were assessed to see if they can recover following the introduction of climbing instead of felling the palms for fruit harvesting. The dataset was collected in collaboration with the Instituto de Investigaciones de la Amazonia Peruana (IIAP), the Wildlife Conservation Society (WCS), and the Servicio Nacional de Áreas Naturales Protegidas del Perú (SERNANP). This work was supported by the Natural Environment Research Council (Grants NE/V018760/1 and NE/V018760/2)." ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "Location of each corner of the plot was recorded using a handheld GPS. Fieldwork was undertaken in August and September 2022 and August 2023. The census was carried out before fruit harvesting, except in San Juan, where fruit harvesting had begun a few days earlier. In each plot, we counted all individuals of M. flexuosa ≥0.4 m tall and classified them into three size classes: short saplings (0.4-1.49 m total height), tall saplings (≥1.5 m total height and without stem or with stem height <1.3 m), and pole stems (≥4 m total height and with stem height ≥1.3 m). All seedlings <0.4 m were counted in a subplot of 5 m × 100 m. For each pole stem, we recorded the life stage as juvenile (<15 m total height), subadult (≥15 m total height without flowers or fruits), or male/female adult (≥15 m total height with inflorescences or infructescences). The sex of each adult was assessed by observing reproductive structures either on the palms using binoculars or on the ground around the base of the stem. We counted the number of racemes with fruits for each female adult individual. Peat thickness was measured in the centre of each plot using a stick. Peat was identified in the field as a substrate consisting of predominantly wet, partially decomposed organic matter of mid to dark brown colour and at least 30 cm thick. Total height of saplings was estimated using a stick with marks at 0.4 and 1.5 m, while the total height of pole stems was measured using a Suunto clinometer. Binoculars (Bushnell 40X60) were used to determine the sex of adult palms in the field. A protocol to identify the different palm sizes was developed to ensure consistency in data collection among field team members. Sites were selected with local community members implementing the management plans and were checked against Landsat imagery in the field." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((-74.517 -4.9, -74.517 -4.583, -73.8 -4.583, -73.8 -4.9, -74.517 -4.9))"^^geo:wktLiteral ; ] ; dcterms:temporal [ a dcterms:PeriodOfTime ; dcat:startDate "2022-08-01"^^xsd:date ; dcat:endDate "2023-08-31"^^xsd:date ; ] ; dcat:contactPoint :6d116530-2c6a-4f28-8d42-65100a582ca1_c0 ; dcterms:publisher ; dcterms:subject , , , , ; prov:wasGeneratedBy ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2026-06-12"^^xsd:date ; dcat:landingPage , ; dcterms:license ; dcterms:accessRights ; dcterms:theme , ; 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 , , :6d116530-2c6a-4f28-8d42-65100a582ca1_a2, :6d116530-2c6a-4f28-8d42-65100a582ca1_a3 ; dcterms:language . :6d116530-2c6a-4f28-8d42-65100a582ca1_c0 a foaf:Person ; foaf:name "Euridice Nora Honorio Coronado" ; vcard:hasEmail "eurihc@yahoo.com" ; 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 "Honorio Coronado, E.N." ; foaf:familyName "Honorio Coronado" ; foaf:givenName "Euridice N" ; vcard:hasEmail "e.honorio@kew.org" ; foaf:member [foaf:name "Royal Botanic Gardens, Kew"] ; . a foaf:Person ; foaf:name "Grandez Rios, J.M." ; foaf:familyName "Grandez Rios" ; foaf:givenName "Julio M" ; vcard:hasEmail "jgrandez@iiap.gob.pe" ; foaf:member [foaf:name "Instituto de Investigaciones de la Amazonía Peruana (IIAP)"] ; . :6d116530-2c6a-4f28-8d42-65100a582ca1_a2 a foaf:Person ; foaf:name "Isasi-Catalá, E." ; foaf:familyName "Isasi-Catalá" ; foaf:givenName "Emiliana" ; vcard:hasEmail "eisasi@wcs.org" ; foaf:member [foaf:name "Wildlife Conservation Society Peru (WCS)"] ; . :6d116530-2c6a-4f28-8d42-65100a582ca1_a3 a foaf:Person ; foaf:name "Ramirez Chávez, J." ; foaf:familyName "Ramirez Chávez" ; foaf:givenName "Jacqueline" ; vcard:hasEmail "jramirez@sernanp.gob.pe" ; foaf:member [foaf:name "Servicio Nacional de Áreas Naturales Protegidas por el Estado (SERNANP)"] ; . a skos:Concept; skos:prefLabel "Environmental survey"; rdfs:label "Environmental survey" . a skos:Concept; skos:prefLabel "Phenology"; rdfs:label "Phenology" . a skos:Concept; skos:prefLabel "sustainable forest management"; rdfs:label "sustainable forest management" . a skos:Concept; skos:prefLabel "natural regeneration"; rdfs:label "natural regeneration" . a skos:Concept; skos:prefLabel "fruit"; rdfs:label "fruit" . a foaf:Organization ; foaf:name "Royal Botanic Gardens, Kew" . a prov:Activity ; rdfs:label "NERC Knowledge Exchange Fellowship" .
