A data dictionary from the National Oceanic and Atmospheric Administration, last updated March 2026, standardizing terminology for threats to salmonid populations. It defines categories for ecological concerns, limiting factors, and threats to enable consistent cross-dataset comparisons for recovery planning. The dictionary relates threats, ecological dynamics, and life history stages to support management action evaluation.
Use Cases
- Standardizing threat and limiting factor terminology across different salmon recovery datasets based on the defined ecological concern categories.
- Linking habitat restoration project data to specific ecological concerns and life history stages using the dictionary's relational structure.
- Assessing changes in habitat threats over time by applying the consistent data dictionary categories to historical and current status reports.
- Evaluating the impact of hydro, hatchery, and invasive species threats by mapping them to the defined population-level effect categories.
Strengths
- Provides a standardized vocabulary developed by NOAA for consistent threat assessment across populations and datasets.
- Dictionary structure defines relationships between threats, ecological concerns, and life history stages, aiding analysis.
- Designed for integration with existing datasets, such as restoration project data, to enable direct comparisons.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided as a PDF, which may require extraction or conversion for programmatic use.
