Application assistance

Thank you for your interest in organizing your Tree Team to conduct a Park Tree Inventory. The Tree Inventory Project is a long-term project, and requires a dedicated group of community members to organize and work together. 

Applications for 2018 Park Tree Inventories are no longer being accepted. To join us in parks this summer, register for workdays here.  If you have any questions about the application process please email

Steps of a park inventory

  1. Before the inventory: Neighborhood Tree Teams (or a group tree-loving neighbors) begin by organizing their group and selecting a park to propose for the inventory. After their application has been approved, neighborhood organizers attend a planning workshop, and then begin recruiting volunteers for workdays. 

  2. During the inventory: A Team Leader Training is held to train volunteers in the parks tree inventory protocol.  Park inventory workdays – typically 2 per park  – begin soon after and continue throughout the summer. Neighborhood organizers help set-up and clean-up for each workday, and Urban Forestry provides staff coordination, refreshments, and supplies for workdays. At workdays, a trained team leader is paired up with untrained volunteers to complete data collection sections, and a volunteer arborist is available for tree identification questions. Neighborhood organizers continue to recruit volunteers as needed for workday events throughout the summer.

  3. After the inventory: Urban Forestry staff review findings with neighborhood organizers and build an online, interactive tree map of their park. The public is invited to attend the annual Tree Summit to celebrate our work and discuss inventory-wide findings. This summit is also a time for neighborhoods to form Tree Teams and continue work on Neighborhood Tree Plans that state short and long term goals for tree care, as well as actions to meet goals. After the summit, Teams continue to meet on their own. Urban Forestry provides staff support, expertise, and event coordination for tree care actions.

To help prepare a strong application, Urban Forestry offers applicants the following suggestions:

  • Seek out a group of neighbors who are also interested in urban forestry issues, and work together to commit to the project. An inventory is only one aspect of a Tree Team's work which can be used to build community tree outreach and stewardship within a neighborhood. To be successful, this requires a group of committed citizens within the community to work together to accomplish tree-related goals to improve the urban forest.
  • Contact your neighborhood association and seek their support for the project. Encourage them to pass a resolution stating support and form a committee to assist you.
  • Recruit neighbors and sign up together for Urban Forestry's Neighborhood Tree Steward course. This 7 session course is offered annually in September and October and is an excellent opportunity to network with other volunteers conducting tree projects in their neighborhoods.
  • Participate in Urban Forestry workshops. These provide an opportunity to learn about stewardship of the urban forest, and may help you to recruit others to help with your community.
  • Don't have a Tree Team in your neighborhood and worried you'll be the only organizer for your park? Don't worry! Urban Forestry may be able to connect you with tree lovers in your neighborhood, and provide extra support to your group. Start by applying to have your park inventoried, and let us know in your application that you'll need extra help. 

We appreciate your interest in the program and look forward to seeing your application!
