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" or "Medium", 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 > 600 in "Shallow" ReefDepthZone
- AcousticIntensity > 800 in any ReefDepthZone
RESILIENCE INDICATORS (Apply after primary indicators):
4. 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.
5. If BiodiversityIndex is "High" or "Very High" AND BleachingEventsPerYear is "Constant" BUT:
- ReefDepthZone is "Mid-depth" or "Deep" AND
- AcousticIntensity < 400 AND
- PollutionLevel is NOT "Critical"
THEN classify as HEALTHY.
STRESS COMBINATIONS (Apply after resilience indicators):
6. If BiodiversityIndex is "Medium" or "Low" AND THREE OR MORE of these conditions are true, classify as STRESSED:
- CurrentFlowQuality is "Poor" or "Fair"
- AlgalCoverage is "Heavy" or "Extensive"
- BleachingEventsPerYear is "Frequent" or "Constant"
- PollutionLevel is "High" or "Critical"
- ReefIntegrityScore is "Moderate" or worse
- AcousticIntensity > 500 in "Shallow" ReefDepthZone
- ReefAverageAge < 30
7. If BleachingEventsPerYear is "Constant" AND PollutionLevel is "High" or "Critical" AND BiodiversityIndex is NOT "Very High", classify as STRESSED.
8. If AcousticIntensity > 700 in "Shallow" ReefDepthZone OR AcousticIntensity > 850 in ANY ReefDepthZone, classify as STRESSED, UNLESS BiodiversityIndex is "Very High" AND ReefIntegrityScore is "Excellent".
REEF HEALTH INDICATORS (Apply after stress combinations):
9. 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"
10. If PredatorActivityLevel is "Moderate Low" 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:
11. 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/High PollutionLevel, Poor/Very Poor ReefIntegrityScore), classify as STRESSED
DEFAULT RULE:
12. If none of the above rules provide a clear classification, evaluate the presence of positive vs. negative factors:
- Count positive factors (weighted):
* Very High BiodiversityIndex (3 points)
* High BiodiversityIndex (2 points)
* Excellent CurrentFlowQuality (2 points)
* Good CurrentFlowQuality (1 point)
* Minimal AlgalCoverage (2 points)
* Sparse AlgalCoverage (1 point)
* Excellent ReefIntegrityScore (2 points)
* Good ReefIntegrityScore (1 point)
* ReefAverageAge > 45 (1 point)
* NearbyHealthyReef present (1 point)
* Low PollutionLevel (1 point)
* ReefDepthZone "Mid-depth" or "Deep" with AcousticIntensity < 400 (1 point)
- Count negative factors (weighted):
* Low BiodiversityIndex (2 points)
* Medium BiodiversityIndex (1 point)
* Poor CurrentFlowQuality (2 points)
* Fair CurrentFlowQuality (1 point)
* Extensive AlgalCoverage (2 points)
* Heavy AlgalCoverage (1 point)
* Constant BleachingEventsPerYear (2 points)
* Frequent BleachingEventsPerYear (1 point)
* Critical PollutionLevel (2 points)
* High PollutionLevel (1 point)
* Poor/Very Poor ReefIntegrityScore (2 points)
* Moderate ReefIntegrityScore (1 point)
* AcousticIntensity > 700 in Shallow zone (2 points)
* AcousticIntensity > 500 in Shallow zone (1 point)
* AcousticIntensity > 800 in any zone (1 point)
- If positive factor points ≥ negative factor points, classify as HEALTHY
- Otherwise, classify as STRESSED
