- Observation Tree mortality ranged from 14 to 100 percent among plots and averaged 47.7 percent.
- Observation Total basal area fell by 9 to 100 percent among plots, averaging 42.4 percent.
- Observation Mortality increased by 9 percent between the 7 and 18 month surveys.
- Association Species composition was strongly associated with plot mortality.

- Association Canopy height had no clear relationship with tree damage.
- Observation Over 80 percent of surviving R. mangle had less than 50 percent crown damage.
- Observation About 60 percent of surviving L. racemosa had 75–100% crown loss.
- Observation The share of R. mangle in the 50 to 100 percent crown damage class rose from 16 to 36 percent.
