Round ID: 299 Prompt used: # 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.
