Great Lakes eDNA Monitoring for Invasive Species, 2024-2025

Environmental DNA (eDNA) metabarcoding results from the U.S. Fish and Wildlife Service's Great Lakes Early Detection Monitoring program for 2024 and 2025. The data is structured across three linked tables detailing sampling sites, collection processes, and taxonomic identifications. The datasets are provided by the Department of the Interior and were last updated in April 2026.

Use Cases

• Detect aquatic invasive species based on eDNA metabarcoding results.
• Analyze spatial distribution of species based on linked geospatial site information.
• Study sampling methodology effectiveness based on equipment and collection process details.
• Model biodiversity changes over time using the 2024 and 2025 survey years.

Strengths

• Data is structured across three logically linked tables (Site, Sample, ID) for comprehensive event tracking.
• Covers two consecutive survey years (2024 and 2025) for temporal analysis.
• Includes a dedicated Data Dictionary file for field documentation.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent from the provided metadata; field semantics must be inferred after download.
