Norfolk City Tree Inventory with Species and Location Data

City-managed trees in Norfolk, Virginia, including those on public property, streets, and rights-of-way. The inventory was initially conducted by Norfolk Master Gardeners in the late 1990s and early 2000s, with ongoing updates by City Staff. Records are updated in the Open Data Portal every weekday.

Use Cases

• Analyze tree species distribution and diversity across Wards and Civic Leagues using the Species, Common Name, and Ward columns.
• Map tree locations for urban planning and maintenance scheduling using the Latitude, Longitude, and Location fields.
• Assess tree size and maturity demographics by analyzing Trunk Diameter and Trunk Diameter Range columns.
• Identify potential planting sites or canopy gaps by correlating Tree ID density with Superward or US Counties data.

Strengths

• Dataset includes multiple geospatial identifiers per record: Latitude/Longitude Point, Latitude, Longitude, and Location.
• Contains detailed botanical classification data with columns for Species, Common Name, and Genus.
• Records are updated on the Open Data Portal every weekday, indicating active maintenance.

Limitations

• Primary inventory data is over 20 years old (from the late 1990s/early 2000s), leading to potential staleness for older records.
• No official re-inventory by certified arborists has been conducted since the original survey, which may affect data accuracy.
• The total number of rows (tree records) and the spatial completeness of the inventory are unknown.
