Stream Benthic Invertebrates in Prince Edward Island National Park

Annual monitoring of stream benthic invertebrates in PEI National Park assesses aquatic health through biodiversity and pollution tolerance. Samples are sorted and classified to the lowest possible taxonomic level, with community health evaluated using Simpson’s reciprocal index and the Hilsenhoff Biotic Index. The dataset is produced by Parks Canada using Environment Canada's CABIN stream monitoring network methods.

Use Cases

• Assessing stream health based on biodiversity metrics like Simpson’s reciprocal index mentioned in the description
• Evaluating organic pollution levels based on species tolerance scores from the Hilsenhoff Biotic Index
• Monitoring long-term trends in benthic invertebrate community composition and abundance
• Comparing aquatic ecosystem conditions against thresholds derived from research on PEI's low-order streams

Strengths

• Data collection follows standardized Environment Canada CABIN network methods
• Includes calculated biodiversity and pollution tolerance indices (Simpson’s reciprocal, Hilsenhoff Biotic)
• Taxonomic classification is performed to the lowest possible level

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
