Round ID: 81
Prompt used:
Classify coral reef health as either "Healthy" or "Stressed" based on the following rules:
**PRIMARY STRESS INDICATORS (if any apply, classify as Stressed):**
1. If ReefIntegrityScore is "Very Poor" → Stressed
2. If BleachingEventsPerYear is "Constant" AND CoralAgeEstimate ≤ 15 years → Stressed
3. If BleachingEventsPerYear is "Frequent" AND PollutionLevel is "High" → Stressed
**PRIMARY HEALTH INDICATORS (override stress indicators):**
1. If ReefIntegrityScore is "Excellent" AND BiodiversityIndex is "High" → Healthy
2. If BleachingEventsPerYear is "Rare" AND ReefIntegrityScore is at least "Good" → Healthy
**SECONDARY ASSESSMENT (if primary rules don't apply):**
Count stress factors:
- BleachingEventsPerYear is "Frequent" or "Constant" (+2 points)
- PollutionLevel is "High" (+1 point)
- ReefIntegrityScore is "Poor" (+1 point)
- CoralAgeEstimate ≤ 10 years (+1 point)
- PredatorActivityLevel is "Severe" (+1 point)
Count health factors:
- BiodiversityIndex is "High" or "Very High" (+1 point)
- ReefIntegrityScore is "Good" or "Excellent" (+2 points)
- BleachingEventsPerYear is "Rare" (+1 point)
- PollutionLevel is "Low" (+1 point)
**FINAL DECISION:**
- If stress points > health points → Stressed
- If health points ≥ stress points → Healthy

Prompt used:
Classify coral reef health as either "Healthy" or "Stressed" based on the following rules:
**CLASSIFY AS STRESSED if ANY of the following conditions are met:**
1. **Critical Structural Damage**: If ReefIntegrityScore = "Very Poor", classify as Stressed
2. **Critical Pollution with Poor Structure**: If PollutionLevel = "Critical" AND ReefIntegrityScore = "Poor", classify as Stressed
3. **Extreme Acoustic Stress**: If AcousticIntensity ≥ 1200, classify as Stressed
4. **Young Reef with High Acoustic Stress**: If ReefAverageAge ≤ 30 AND AcousticIntensity ≥ 700, classify as Stressed
5. **Poor Flow + Short Observation**: If CurrentFlowQuality = "Poor" AND ObservationDuration ≤ 35 days, classify as Stressed
6. **Young Reef with Multiple Stressors**: If ReefAverageAge ≤ 30 AND any TWO of the following are true:
- CurrentFlowQuality = "Poor" or "Fair"
- PollutionLevel = "High" or "Critical"
- BleachingEventsPerYear = "Constant"
- PredatorActivityLevel = "None"
7. **Multiple Moderate Stressors**: If any THREE of the following are true:
- CurrentFlowQuality = "Poor" or "Fair"
- PollutionLevel = "High" or "Critical"
- ReefIntegrityScore = "Poor"
- PredatorActivityLevel = "High", "Severe", or "Extreme"
- BleachingEventsPerYear = "Frequent" or "Constant"
8. **High Pollution with Poor Flow**: If PollutionLevel = "High" AND CurrentFlowQuality = "Poor" AND ReefAverageAge ≤ 35, classify as Stressed
9. **Insufficient Observation with Stress Indicators**: If ObservationDuration ≤ 30 days AND any TWO of the following are true:
- CurrentFlowQuality = "Poor" or "Fair"
- PollutionLevel = "High" or "Critical"
- ReefIntegrityScore = "Poor" or "Very Poor"
- PredatorActivityLevel = "High", "Severe", or "Extreme"
**CLASSIFY AS HEALTHY if:**
- None of the above stress conditions are met
- ReefIntegrityScore = "Excellent" AND CurrentFlowQuality = "Excellent" AND PollutionLevel = "Low"
**DEFAULT CLASSIFICATION:**
If none of the explicit stress conditions are met and the reef doesn't qualify for the excellent health criteria, classify as Healthy.
