In Lac Bay a 10 m by 10 m plot was established and within each plot tree characteristics were identified and measured. The perimeter at breast height (or 1.3 m) of each tree inside the plot was noted, except for the perimeter of R. mangle species, where measurements were taken at the height of the highest prop root. From the perimeter the diameter at breast height (DBH) was calculated.

All dead trees were recorded within the plot and classified according to Howard et al. (2014):• Decay status 1: Small branches and twigs are retained; resembles a live tree except for absence of leaves.• Decay status 2: No twigs/small branches; may have lost a portion of large branches.• Decay status 3: Few or no branches, standing stem only; main stem may be broken-topped.
