CORAL REEF HEALTH ASSESSMENT RULES
Analyze the provided data for each coral reef and classify it as either "Healthy" or "Stressed" based on the following set of rules. Apply these rules in sequence.
PRIMARY INDICATORS (These take precedence):
1. If BiodiversityIndex is "Very High" AND ReefIntegrityScore is "Excellent" AND CurrentFlowQuality is "Excellent" or "Good", classify as HEALTHY regardless of other factors, UNLESS:
- AcousticIntensity > 950 in ANY ReefDepthZone
- PollutionLevel is "Critical" AND BleachingEventsPerYear is "Constant" AND ReefDepthZone is "Shallow" AND AlgalCoverage is "Heavy" or "Extensive"
2. If CurrentFlowQuality is "Poor" AND ReefIntegrityScore is "Poor" or "Very Poor" AND BiodiversityIndex is "Low", classify as STRESSED.
3. If BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is "Good" or "Excellent", classify as HEALTHY, UNLESS:
- PollutionLevel is "Critical" AND BleachingEventsPerYear is "Constant" AND ReefDepthZone is "Shallow" AND AlgalCoverage is "Heavy" or "Extensive"
- AcousticIntensity > 900 in "Shallow" ReefDepthZone AND PollutionLevel is "Critical"
HIGH BIODIVERSITY WITH POOR FLOW INDICATORS:
4. If BiodiversityIndex is "High" or "Very High" AND CurrentFlowQuality is "Poor" BUT ReefDepthZone is "Mid-depth" or "Deep" AND AcousticIntensity < 500, classify as HEALTHY, unless PollutionLevel is "Critical" AND AlgalCoverage is "Heavy" or "Extensive".
5. If BiodiversityIndex is "High" or "Very High" AND CurrentFlowQuality is "Poor" BUT ReefIntegrityScore is "Moderate" or better AND AcousticIntensity < 400, classify as HEALTHY, even if ReefDepthZone is "Shallow".

- CurrentFlowQuality is "Excellent" or "Good" AND AlgalCoverage is NOT "Extensive"
- ReefIntegrityScore is "Good" or "Excellent" AND PollutionLevel is NOT "Critical"

15. If BiodiversityIndex is "Medium" AND ReefDepthZone is "Mid-depth" or "Deep" AND AcousticIntensity < 500 AND ReefIntegrityScore is "Moderate" or better, classify as HEALTHY, even with BleachingEventsPerYear "Constant" (indicates depth protection).
16. If CurrentFlowQuality is "Poor" BUT ReefDepthZone is "Deep" AND BiodiversityIndex is "High" AND AcousticIntensity < 700, classify as HEALTHY (depth compensates for poor flow).

# Coral Reef Health Classification Rules
Evaluate each coral reef using the following set of rules to determine if it is HEALTHY or STRESSED. Apply these rules sequentially and classify accordingly.
## Rule 1: Current Flow and Integrity Assessment
- If CurrentFlowQuality is "Poor" AND ReefIntegrityScore is "Very Poor", classify as STRESSED.
- If CurrentFlowQuality is "Excellent" AND ReefIntegrityScore is "Excellent" or "Good", classify as HEALTHY unless contradicted by Rule 6.
- If CurrentFlowQuality is "Poor" but ReefIntegrityScore is "Excellent", evaluate other positive factors before classification (see Rule 5).
## Rule 2: Pollution and Biodiversity Assessment
- If PollutionLevel is "Critical" AND BiodiversityIndex is "Low", classify as STRESSED.
- If BiodiversityIndex is "High" or "Very High", consider the reef POTENTIALLY HEALTHY (confirm with Rules 5 and 6).
- If PollutionLevel is "Critical" or "High" but BiodiversityIndex is "High" or "Very High" AND ReefAverageAge > 35, consider the reef POTENTIALLY HEALTHY (confirm with Rules 5 and 6).
## Rule 3: Reef and Coral Age Evaluation
- If CoralAgeEstimate ≤ 11 AND ReefAverageAge < 28, classify as STRESSED unless BiodiversityIndex is "High" or "Very High".
- If CoralAgeEstimate ≥ 16 AND ReefAverageAge > 35 AND BiodiversityIndex is not "Low", consider the reef POTENTIALLY HEALTHY (confirm with Rules 5 and 6).
## Rule 4: Bleaching and Algal Coverage Assessment
- If BleachingEventsPerYear is "Constant" AND AlgalCoverage is "Extensive" AND BiodiversityIndex is "Low" or "Medium", classify as STRESSED.
- If BleachingEventsPerYear is "Constant" but BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is "Excellent" or "Good", this is not automatically indicative of stress (evaluate using Rules 5 and 6).
## Rule 5: Positive Health Indicators
If THREE OR MORE of the following conditions are met, classify as HEALTHY unless Rule 6 applies:
- CurrentFlowQuality is "Excellent" or "Good"
- BiodiversityIndex is "High" or "Very High"
- AlgalCoverage is "Minimal" or "Sparse"
- ReefIntegrityScore is "Excellent" or "Good"
- PollutionLevel is "Low" or "Moderate"
- ReefAverageAge > 35
- CoralAgeEstimate > 15
## Rule 6: Critical Stress Indicators
If ANY THREE of the following conditions are met, classify as STRESSED regardless of other factors:
- AcousticIntensity > 850
- PollutionLevel is "Critical" AND BiodiversityIndex is not "High" or "Very High"
- CurrentFlowQuality is "Poor" AND ReefIntegrityScore is "Very Poor" or "Poor"
- BleachingEventsPerYear is "Frequent" AND AlgalCoverage is "Extensive"
- CoralAgeEstimate < 10 AND ReefAverageAge < 25
## Rule 7: Additional Health Indicators
If a reef meets TWO of these conditions, classify as HEALTHY unless it meets Rule 6:
- ReefIntegrityScore is "Excellent" AND any one other positive indicator from Rule 5
- BiodiversityIndex is "High" or "Very High" AND ReefAverageAge > 35
- BiodiversityIndex is "High" or "Very High" AND AlgalCoverage is "Minimal"
## Default Rule
If no clear classification has been made from the above rules:
- If TWO OR MORE of these key indicators (BiodiversityIndex, ReefIntegrityScore, CurrentFlowQuality, PollutionLevel) are positive, AND AcousticIntensity < 600, classify as HEALTHY.
- If TWO OR MORE of these key indicators are negative, OR AcousticIntensity > 600 AND either PollutionLevel is "High"/"Critical" or CurrentFlowQuality is "Poor", classify as STRESSED.
- In uncertain cases where there is a balanced mix of positive and negative indicators, prioritize BiodiversityIndex and ReefIntegrityScore in the final decision.
When evaluating, apply rules in sequence but prioritize Rules 5 and 6 when their conditions are conclusively met.
