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", classify as HEALTHY regardless of other factors, UNLESS:
- AcousticIntensity > 800 in ANY ReefDepthZone
- PollutionLevel is "Critical" AND BleachingEventsPerYear is "Constant"
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"
- AcousticIntensity > 650 in "Shallow" ReefDepthZone
MEDIUM BIODIVERSITY INDICATORS (New section):
4. If BiodiversityIndex is "Medium" BUT CurrentFlowQuality is "Excellent" AND ReefIntegrityScore is "Good" or "Excellent", classify as HEALTHY, UNLESS:
- AcousticIntensity > 500 in "Shallow" ReefDepthZone AND PollutionLevel is "High" or "Critical"
5. If BiodiversityIndex is "Medium" AND ReefIntegrityScore is "Excellent" AND ReefAverageAge > 50, classify as HEALTHY, even with BleachingEventsPerYear "Constant" (indicates resilience over time).
RESILIENCE INDICATORS:
6. If BiodiversityIndex is "High" or "Very High" AND CurrentFlowQuality is "Poor" BUT:
- ReefIntegrityScore is "Good" or "Excellent" AND
- PollutionLevel is "Low" or "Moderate" AND
- AlgalCoverage is NOT "Extensive"
THEN classify as HEALTHY.
7. If BiodiversityIndex is "Medium" AND BleachingEventsPerYear is "Constant" BUT:
- ReefDepthZone is "Mid-depth" or "Deep" AND
- AcousticIntensity < 400 AND
- ReefIntegrityScore is "Excellent" AND
- PollutionLevel is NOT "Critical"
THEN classify as HEALTHY.
8. If CurrentFlowQuality is "Excellent" AND AlgalCoverage is "Minimal" AND ReefIntegrityScore is "Moderate" or better, classify as HEALTHY, even if BiodiversityIndex is "Medium" (addressing a common false negative pattern).
STRESS COMBINATIONS:
9. If BiodiversityIndex is "Medium" or "Low" AND THREE OR MORE of these conditions are true, classify as STRESSED:
- CurrentFlowQuality is "Poor"
- AlgalCoverage is "Heavy" or "Extensive"
- BleachingEventsPerYear is "Frequent" or "Constant"
- PollutionLevel is "High" or "Critical"
- ReefIntegrityScore is "Poor" or "Very Poor"
- AcousticIntensity > 500 in "Shallow" ReefDepthZone
- ReefAverageAge < 25
10. If BleachingEventsPerYear is "Constant" AND PollutionLevel is "Critical" AND (BiodiversityIndex is "Low" OR CurrentFlowQuality is "Poor"), classify as STRESSED.
11. If AcousticIntensity > 700 in "Shallow" ReefDepthZone AND (BleachingEventsPerYear is "Constant" OR PollutionLevel is "High" or "Critical"), classify as STRESSED, UNLESS BiodiversityIndex is "Very High" AND ReefIntegrityScore is "Excellent".
REEF HEALTH INDICATORS:
12. If THREE OR MORE of these conditions are true, classify as HEALTHY:
- CurrentFlowQuality is "Excellent"
- AlgalCoverage is "Minimal"
- BiodiversityIndex is "High" or "Very High"
- ReefIntegrityScore is "Good" or "Excellent"
- ReefMonitoringDuration is "> 6 years" AND SurveyorExperience is "Yes"
- ReefAverageAge is > 45
- NearbyHealthyReef is "Adjacent" or "Nearby"
- PollutionLevel is "Low"
13. If PredatorActivityLevel is "Moderate Low" or "High" AND BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is NOT "Poor" or "Very Poor", classify as HEALTHY (indicates a balanced ecosystem).
EXPERT ASSESSMENT WEIGHT:
14. If ObservationDuration is > 70 AND SurveyorExperience is "Yes" AND ReefMonitoringDuration is "> 6 years", then:
- If they identified three or more positive factors (Good/Excellent CurrentFlowQuality, Minimal/Sparse AlgalCoverage, High/Very High BiodiversityIndex, Good/Excellent ReefIntegrityScore), classify as HEALTHY
- If they identified three or more negative factors (Poor CurrentFlowQuality, Extensive AlgalCoverage, Constant BleachingEventsPerYear, Critical PollutionLevel, Poor/Very Poor ReefIntegrityScore), classify as STRESSED
DEFAULT RULE:
15. If none of the above rules provide a clear classification, evaluate the presence of positive vs. negative factors:
- Count positive factors (weighted):
* Excellent CurrentFlowQuality (3 points)
* Good CurrentFlowQuality (2 points)
* Fair CurrentFlowQuality (1 point)
* Minimal AlgalCoverage (2 points)
* Sparse AlgalCoverage (1 point)
* Very High BiodiversityIndex (3 points)
* High BiodiversityIndex (2 points)
* Medium BiodiversityIndex (1 point)
* Excellent ReefIntegrityScore (3 points)
* Good ReefIntegrityScore (2 points)
* Moderate ReefIntegrityScore (1 point)
* ReefAverageAge > 50 (2 points)
* ReefAverageAge > 30 (1 point)
* NearbyHealthyReef present (1 point)
* Low PollutionLevel (2 points)
* Moderate PollutionLevel (1 point)
* ReefDepthZone "Mid-depth" or "Deep" with AcousticIntensity < 400 (1 point)
- Count negative factors (weighted):
* Poor CurrentFlowQuality (3 points)
* Fair CurrentFlowQuality paired with BleachingEventsPerYear "Constant" (1 point)
* Extensive AlgalCoverage (2 points)
* Heavy AlgalCoverage (1 point)
* Constant BleachingEventsPerYear (2 points)
* Frequent BleachingEventsPerYear (1 point)
* Critical PollutionLevel (3 points)
* High PollutionLevel (2 points)
* Poor/Very Poor ReefIntegrityScore (2 points)
* AcousticIntensity > 700 in Shallow zone (2 points)
* AcousticIntensity > 500 in Shallow zone (1 point)
* AcousticIntensity > 800 in any zone (1 point)
* Low BiodiversityIndex (2 points)
- If positive factor points >= negative factor points, classify as HEALTHY
- Otherwise, classify as STRESSED
