Salinity filtering and biotic structure drive foliar trait convergence and functional diversity patterns in Sundarbans mangroves

This dataset contains community-level vegetation data, species-level foliar functional traits, and associated soil environmental variables collected from 59 georeferenced plots across the Sundarbans mangrove forest in Bangladesh. The study aimed to assess how soil salinity shapes community-weighted trait composition and functional diversity within mangrove ecosystems. Data were collected during the dry season of 2021–2022 and include both raw and processed variables used in the analyses presented in the associated publication.
