Field measurement data for the mangroves bordering the lagoons of La Mancha and El Llano, Mexico

Between 27 June and 13 July 2022, a total of 11 field plots were investigated, where six plots were located at El Llano lagoon, and five at La Mancha lagoon. Plot size varied in relation to stand density. In the lagoon of El Llano, three plots of 10 × 10 m were delimited in the west of the lagoon and three plots of the same size on the east, neighbouring a system of stabilized dunes. In La Mancha lagoon, two plots of 10 × 10 m and two 15 × 15 m subplots of 30 × 30 m permanent plots located in the north, and one plot of 20 × 20 m for large R. mangle trees were sampled in the southeast of the lagoon. Species id, stem diameter (cm) at 1.3 m from ground surface, and tree height (m) were recorded within each plot. Additionally, trunk diameter at lowest living branch, canopy width and length in the case of shrubs or young trees, and diameter above the highest prop root in the case of R. mangle were also recorded.
