Mid-Columbia River NWRC and Central Washington NWRC: Invasive Plant Inventory and Early De

An Access Database tool and CSV tables from a 2019 workshop generate numerical scores to rank invasive plant species and areas for inventory priority. The Department of the Interior archived the workshop's data tables to preserve results independent of updates to the master database. Each workshop output includes a zipped Access database and 2-3 standalone CSV files.

Use Cases

• Prioritizing areas for invasive plant surveys based on calculated area scores.
• Ranking invasive species for management action based on calculated species scores.
• Analyzing workshop-derived threat assessments based on yes/no/unknown questionnaire responses.

Strengths

• Data tables are archived to preserve workshop results independently of the master database.
• The tool uses a structured questionnaire format with yes/no/unknown or list-based responses.
• Outputs include both a database tool and open source CSV files for flexibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is dated 2026-03-04.
