The data was collated between 2004 and 2019 through fieldwork to compile an inventory of mangrove flora on 13 islands located in the Setiu Lagoon. Field inventories using circular sample plots of 5.6 m radius and square plots of 100 m × 20 m were employed in the study. In each plot, the mangrove plant species were enumerated and identified. A total of 74 species belonging to 39 families were recorded, comprising of 23 exclusive, 49 non-exclusive and 2 associate mangrove species. Pulau Telaga Tujuh supported the most diverse mangrove with 47 species in contrast to Pulau Tok Ba and Pulau Gemia that supported the least number of mangroves with only 10 species recorded eaData in brief108020https://www.ebi.ac.uk/biostudies/studies/S-EPMC8960900biostudies-literatureMangrove floristic composition dataset of the Setiu Lagoon, Terengganu Malaysia.PMC8960900Jamaludin PNMuhammad Nor SMStephen ERSahari MSIYusof RMSalam MRWan Mustaffa WFRazali NAMMokhetar NfalseMangrove floristic composition dataset of the Setiu Lagoon, Terengganu Malaysia.This article documents the composition of plant species collected from the mangrove forest of the Setiu Lagoon, Terengganu.
