Inventory Work Days and Protocol

A Park's tree data are collected during one or two work days, held between June and September. At work days, volunteer teams collect data on tree location, tree species, tree condition, and tree size. Each team is led by a Team Leader who has undergone training in the inventory protocol. Data are collected and mapped using ArcGIS Collector on a mobile device provided by Urban Forestry.

Since the first inventory in 2010, the protocol used for the Tree Inventory Project has evolved to best fit the tree goals of participating neighborhoods. The most current protocol is available in the 2017 Parks Tree Inventory Manual. Following is a list of tools and resources used during training and on work days.


Volunteer Recruitment

Volunteer support is essential in the successful completion of your neighborhood's Parks tree inventory. Not only will data collection move quickly with many helping hands; the involvement of your neighbors and community will encourage a greater sense of collective tree stewardship and neighborhood stewardship. Feel free to use the following resources to help you recruit volunteers for inventory workdays!
