- Observation Damage intensity varied across the mangrove landscape.
- 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.
