SDOT Trees: Seattle Street Tree Inventory with Condition and Species Data

Seattle's inventory of publicly and privately maintained trees within the public right of way, collected by the Seattle Department of Transportation. The dataset includes information on tree condition, location, size, species, and maintenance responsibility, with the intent to predict maintenance needs and assess species diversification. It is updated daily and was last refreshed on 2026-03-22.

Use Cases

• Predicting tree maintenance needs based on condition and species data.
• Mapping urban tree canopy distribution and diversity based on location and species.
• Analyzing public works resource allocation based on maintenance responsibility records.
• Studying urban biodiversity and species diversification within the street tree population.

Strengths

• Daily refresh cycle ensures data is current.
• Includes multiple key attributes: condition, location, size, species, and maintenance responsibility.
• Available in multiple formats including CSV, JSON, and geospatial formats (KML, GeoPackage).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
