Diameter at breast height (DBH), height, and species were recorded for understory and overstory trees in each subplot. Overstory trees, defined by DBH > 5 cm, were measured within the 7 m subplots. All small understory trees and saplings
(DBH < 5 cm) reaching at least 1.3 m (breast height) were measured in a 2 m radius subplot nested within the 7 m radius subplot. All diameters were measured to the nearest 0.1 cm using a diameter tape. If the tree was dead, a decay class of 1, 2, or 3, as defined by Kauffman and Donato (2012), was recorded in addition to the DBH. Some mangroves have root adaptations that affect the way in which diameter is measured; if a buttress stem was encountered, the diameter was measured at the point directly above the buttress. If a tree had prop roots (e.g., R. mucronata), measurements
were made just above the highest prop root. Height was measured to the nearest 0.5 m for every tree using a hypsometer (Haglof Vertex III, Haglof Inc, Sweden).
