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 > 850 in ANY ReefDepthZone
- PollutionLevel is "Critical" AND BleachingEventsPerYear is "Constant" AND ReefDepthZone is "Shallow"
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"
- AcousticIntensity > 800 in "Shallow" ReefDepthZone
BIODIVERSITY RESILIENCE INDICATORS:
4. If BiodiversityIndex is "High" AND ANY of these additional resilience factors are present:
- ReefDepthZone is "Deep" or "Mid-depth" AND AcousticIntensity < 500
- CurrentFlowQuality is "Excellent" or "Good" AND AlgalCoverage is NOT "Extensive"
- ReefIntegrityScore is "Good" or "Excellent" AND PollutionLevel is NOT "Critical"
- ReefAverageAge > 35 AND PollutionLevel is NOT "Critical"
THEN classify as HEALTHY, even if BleachingEventsPerYear is "Constant" or "Frequent".
5. If BiodiversityIndex is "Medium" AND THREE OR MORE of these resilience factors are present:
- CurrentFlowQuality is "Excellent" or "Good"
- ReefIntegrityScore is "Good" or "Excellent" or "Moderate"
- ReefDepthZone is "Mid-depth" or "Deep" AND AcousticIntensity < 450
- AlgalCoverage is "Minimal" or "Sparse"
- ReefAverageAge > 25
- PollutionLevel is "Low" or "Moderate"
- SurveyorExperience is "Yes"
THEN classify as HEALTHY, even if BleachingEventsPerYear is "Constant".
DEPTH AND FLOW PROTECTIONS:
6. If ReefDepthZone is "Deep" AND AcousticIntensity < 500 AND BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is NOT "Poor" or "Very Poor", classify as HEALTHY, UNLESS PollutionLevel is "Critical" AND AlgalCoverage is "Extensive".
7. 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).
8. If BiodiversityIndex is "Medium" AND ReefDepthZone is "Mid-depth" or "Deep" AND AcousticIntensity < 350 AND ReefIntegrityScore is "Moderate" or better, classify as HEALTHY, even with BleachingEventsPerYear "Constant" (indicates depth protection).
9. If CurrentFlowQuality is "Poor" BUT ReefDepthZone is "Deep" AND BiodiversityIndex is "High" AND AcousticIntensity < 400, classify as HEALTHY (depth compensates for poor flow).
PREDATOR BALANCE INDICATORS:
10. If PredatorActivityLevel is "Moderate Low" or "Moderate High" or "High" AND BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is NOT "Poor" or "Very Poor", classify as HEALTHY (indicates a balanced ecosystem).
11. If PredatorActivityLevel is "Very Low" AND BiodiversityIndex is "High" or "Very High" AND ReefAverageAge > 30, classify as HEALTHY (indicates long-term resilience).
POLLUTION RESILIENCE INDICATORS:
12. If PollutionLevel is "High" or "Critical" BUT ALL of these factors are present:
- ReefDepthZone is "Deep"
- BiodiversityIndex is "High" or "Very High"
- AcousticIntensity < 400
- AlgalCoverage is "Minimal" or "Sparse"
THEN classify as HEALTHY (deep reefs can withstand higher pollution).
13. If PollutionLevel is "High" BUT ALL of these factors are present:
- BiodiversityIndex is "High"
- ReefIntegrityScore is "Good" or "Excellent"
- CurrentFlowQuality is "Excellent"
- ReefDepthZone is "Mid-depth"
THEN classify as HEALTHY (addressing false negative pattern).
STRESS COMBINATIONS:
14. 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" AND ReefDepthZone is "Shallow"
- PollutionLevel is "High" or "Critical" AND CurrentFlowQuality is NOT "Excellent"
- ReefIntegrityScore is "Poor" or "Very Poor"
- AcousticIntensity > 550 in "Shallow" ReefDepthZone
- ReefAverageAge < 25
15. If BleachingEventsPerYear is "Constant" AND PollutionLevel is "Critical" AND BiodiversityIndex is "Low", classify as STRESSED.
16. If AcousticIntensity > 750 in "Shallow" ReefDepthZone AND (BleachingEventsPerYear is "Constant" OR PollutionLevel is "Critical"), classify as STRESSED, UNLESS BiodiversityIndex is "Very High" AND ReefIntegrityScore is "Excellent".
REEF HEALTH INDICATORS:
17. 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 > 35
- NearbyHealthyReef is "Adjacent" or "Nearby"
- PollutionLevel is "Low"
- ReefDepthZone is "Deep" AND AcousticIntensity < 400
18. If ObservationDuration is > 60 AND SurveyorExperience is "Yes" AND AlgalCoverage is "Minimal", classify as HEALTHY, unless THREE OR MORE negative conditions from rule 14 are present.
EXPERT ASSESSMENT WEIGHT:
19. 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 with Shallow ReefDepthZone, Critical PollutionLevel, Poor/Very Poor ReefIntegrityScore), classify as STRESSED
DEFAULT RULE:
20. 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 (4 points)
* High BiodiversityIndex (3 points)
* Medium BiodiversityIndex (1 point)
* Excellent ReefIntegrityScore (3 points)
* Good ReefIntegrityScore (2 points)
* Moderate ReefIntegrityScore (1 point)
* ReefAverageAge > 35 (2 points)
* ReefAverageAge > 25 (1 point)
* NearbyHealthyReef present (1 point)
* Low PollutionLevel (2 points)
* Moderate PollutionLevel (1 point)
* ReefDepthZone "Deep" (3 points)
* ReefDepthZone "Mid-depth" (2 points)
* AcousticIntensity < 300 in any zone (2 points)
* ObservationDuration > 60 AND SurveyorExperience is "Yes" (2 points)
- Count negative factors (weighted):
* Poor CurrentFlowQuality (3 points)
* Fair CurrentFlowQuality paired with BleachingEventsPerYear "Constant" AND ReefDepthZone "Shallow" (2 points)
* Extensive AlgalCoverage (2 points)
* Heavy AlgalCoverage (1 point)
* Constant BleachingEventsPerYear AND ReefDepthZone "Shallow" (3 points)
* Constant BleachingEventsPerYear AND ReefDepthZone "Mid-depth" (1 point)
* Frequent BleachingEventsPerYear AND ReefDepthZone "Shallow" (2 points)
* Critical PollutionLevel (3 points)
* High PollutionLevel (2 points)
* Poor/Very Poor ReefIntegrityScore (2 points)
* AcousticIntensity > 750 in Shallow zone (3 points)
* AcousticIntensity > 550 in Shallow zone (2 points)
* AcousticIntensity > 900 in any zone (2 points)
* Low BiodiversityIndex (2 points)
- If positive factor points > negative factor points, classify as HEALTHY
- Otherwise, classify as STRESSED
