Prompt used:
Predict whether a coral reef is "Healthy" or "Stressed" based on the following rules:
**PREDICT STRESSED IF ANY OF THESE CONDITIONS ARE MET:**
1. **Critical Integrity Rule**: ReefIntegrityScore is "Very Poor" OR "Poor"
2. **Severe Predation Rule**: PredatorActivityLevel is "Severe" AND AlgalCoverage is "Extensive" OR "Heavy"
3. **Poor Flow with High Acoustic Rule**: CurrentFlowQuality is "Poor" AND AcousticIntensity > 600
4. **Young Coral Under Constant Bleaching Rule**: CoralAgeEstimate < 15 AND BleachingEventsPerYear is "Constant" AND BiodiversityIndex is NOT "Very High" AND NOT "High"
5. **Multiple Stress Indicators Rule**: Count how many of these are true:
- CurrentFlowQuality is "Poor"
- AlgalCoverage is "Extensive"
- BiodiversityIndex is "Low" OR "Very Low"
- PollutionLevel is "High"
- PreviousStressIncidents is "Major" OR "Severe"
If 3 or more are true, predict STRESSED
6. **Extreme Algae with Low Diversity Rule**: AlgalCoverage is "Extensive" AND BiodiversityIndex is "Low" OR "Very Low"
**OTHERWISE, PREDICT HEALTHY IF:**
- None of the above stress conditions are met
- OR if BiodiversityIndex is "Very High" AND ReefIntegrityScore is NOT "Very Poor" AND NOT "Poor"
**DEFAULT**: If unclear, predict 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.
