Coral Outplant Survival (COS)
One-year survival of nursery-reared coral fragments planted on restoration reefs. The true yield of the reef program — frags grown but not surviving outplant are effort, not recovery.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Strong | ≥ 70% | OK |
| Marginal | 40–70% | WARN |
| Failing | < 40% | CRIT |
Formula
Outplanted fragments alive at 12 months ÷ outplanted.
