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 CurrentFlowQuality is "Poor" AND any of the following are true, classify as STRESSED:
- BleachingEventsPerYear is "Constant" AND BiodiversityIndex is NOT "High" or "Very High"
- PollutionLevel is "Critical"
- ReefIntegrityScore is "Poor" or "Very Poor"
2. If CurrentFlowQuality is "Excellent" AND ReefIntegrityScore is "Excellent" or "Good" AND BiodiversityIndex is "High" or "Very High" AND AcousticIntensity < 500, classify as HEALTHY.
3. If BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is "Good" or "Excellent" AND PollutionLevel is NOT "Critical" or "High", classify as HEALTHY, UNLESS AcousticIntensity > 600 in a "Shallow" ReefDepthZone.
SECONDARY INDICATORS (Apply if primary indicators don't yield a clear result):
4. If THREE OR MORE of these conditions are true, classify as STRESSED:
- AlgalCoverage is "Extensive" AND BiodiversityIndex is NOT "High" or "Very High"
- BleachingEventsPerYear is "Constant" AND CurrentFlowQuality is "Poor" or "Fair"
- PollutionLevel is "Critical" or "High"
- ReefIntegrityScore is "Poor" or "Very Poor"
- AcousticIntensity > 700 in "Shallow" ReefDepthZone
- AcousticIntensity > 900 in any ReefDepthZone
- PredatorActivityLevel is "Catastrophic" AND BiodiversityIndex is "Low"
5. If THREE OR MORE of these conditions are true, classify as HEALTHY:
- CurrentFlowQuality is "Excellent" or "Good"
- AlgalCoverage is "Minimal" or "Sparse"
- 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"
CRITICAL STRESS COMBINATIONS (Apply after secondary indicators):
6. If BleachingEventsPerYear is "Constant" AND AlgalCoverage is "Extensive" AND AcousticIntensity > 500 AND ReefDepthZone is "Shallow", classify as STRESSED regardless of other factors.
7. If AcousticIntensity > 600 AND ReefDepthZone is "Shallow" AND (BleachingEventsPerYear is "Constant" OR PollutionLevel is "High" or "Critical"), classify as STRESSED.
RESILIENCE INDICATORS (Apply after critical stress combinations):
8. If PredatorActivityLevel is "Severe" or "Moderate Low" AND BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is NOT "Poor" or "Very Poor", classify as HEALTHY (indicates a balanced ecosystem).
9. If BiodiversityIndex is "High" or "Very High" AND ReefAverageAge > 40 AND CurrentFlowQuality is "Good" or "Excellent", classify as HEALTHY despite the presence of one stress factor (such as occasional bleaching or moderate pollution).
EXPERT ASSESSMENT WEIGHT:
10. 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 ReefIntegrityScore), classify as STRESSED
DEFAULT RULE:
11. If none of the above rules provide a clear classification, evaluate the presence of positive vs. negative factors:
- Count positive factors (weighted):
* Excellent CurrentFlowQuality (2 points)
* Good CurrentFlowQuality (1 point)
* Minimal AlgalCoverage (2 points)
* Sparse AlgalCoverage (1 point)
* Very High BiodiversityIndex (2 points)
* High BiodiversityIndex (1 point)
* Excellent ReefIntegrityScore (2 points)
* Good ReefIntegrityScore (1 point)
* ReefAverageAge > 45 (1 point)
* NearbyHealthyReef present (1 point)
- Count negative factors (weighted):
* 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)
* AcousticIntensity > 700 in Shallow zone (2 points)
* AcousticIntensity > 500 in Shallow zone (1 point)
- If positive factor points > negative factor points, classify as HEALTHY
- Otherwise, classify as STRESSED
