WFD Cycle 2 Lake Littoral Invertebrates Classification

A retired dataset containing classification data for macro-invertebrates in lakes, superseded by a newer record. It was produced by the Environment Agency and includes metrics like the Lake Acidification Macro Invertebrate Metric (LAMM) and Ecological Quality Ratio (EQR) scores. The data is formatted in XLSX files.

Use Cases

• Assess anthropogenic acidification impact on lake macro-invertebrate communities based on the LAMM metric.
• Classify lake water quality status from High to Moderate or worse based on deviation from reference conditions.
• Calculate the Confidence of Class (CoC) for Water Framework Directive reporting requirements.
• Compare ecological quality between humic and clear water lakes using separate reference conditions.

Strengths

• Includes the Lake Acidification Macro Invertebrate Metric (LAMM), a species/abundance weighted assessment method.
• Provides classification bands from High to Moderate or worse and calculates a Confidence of Class (CoC) for reporting.
• Uses two sets of reference conditions for Humic and Clear waters.

Limitations

• This dataset has been retired and superseded by a newer record, indicating it is not the current version.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
