Citywide Tree Inventory Underway In Napa

NAPA, CA — A citywide tree inventory is taking place in Napa.

The City of Napa's Parks and Recreation Department contracted with Davey Resource Group, Inc. — DRG— to do the inventory, which began in December 2023 and was expected to take around three months, city officials said in a news release.

Experienced arborists employed as urban foresters by DRG are collecting data on all trees, tree stumps and tree-planting sites in public parks and on city streets and properties. First, they walk by a tree, then they inspect it from the ground up. Based on the conditions at the time of the inspection, the arborists identify the tree's species and its location, measure its diameter and rate its health.

The urban foresters also assess tree risk and suggest the specific maintenance involved. When data collection for a tree is complete, they walk to the next tree and follow the same steps, in the same order, to ensure consistent data collection.

DRG’s urban foresters collect data Monday through Friday and occasionally on weekends but will always be identifiable by their safety vest and hard hats and will carry a badge, city officials said. If residents have questions, they should the Parks and Recreation Administrative Office at 707- 257-9529.
