Volunteer Opportunities

Street tree inventory data collection begins in June. This is a monumental undertaking and we need many volunteers to help us collect and process data! We need volunteers to help fill the following roles:

1. Help collect data during an inventory work day

Volunteers are needed to help collect data on Wednesdays and Saturdays from June through September. Most work days occur from 8:30 am to noon; some Wednesdays are evening events. No experience is necessary, as novice volunteers will be paired with a team leader to identify trees and explain the inventory protocol. Duties include measuring trees, recording data on trees and the site, and mapping trees. Advanced registration via the website is requested.

  • Please register for each inventory day via links posted on the Urban Forestry calendar.
  • View a list of work days by neighborhood or date here.

2. Be an inventory Team Leader

Team Leaders are needed to lead inventory collection routes during work days. This position requires some knowledge of tree identification, attendance at one training session, and commitment to participate in at least three inventory work days. Becoming a Team Leader is an excellent opportunity to improve your tree identification skills and learn more about assessing tree health and site conditions. Please register for Team Leader Training and individual inventory work days via links posted on the inventory calendarView the training guide here.

Team Leaders should attend one of the following training dates. Pre-registration is required: register here.

  • Saturday, June 14. Location to be announced. Morning or afternoon session.
  • Wednesday, June 18 at Hinson Baptist Church at 1137 SE 20th Ave. Morning or afternoon session.

3. Enter Data into ArcGIS

Join Urban Forestry staff at our office in Delta Park to enter inventory data into an ArcGIS database. No experience is necessary - staff will teach you the basics of ArcGIS editing. Shifts are available Monday - Friday from 7 am - 3:30 pm. A 30 hour minimum commitment is requested. 

Data entry volunteers should attend one of the following training dates. Pre-registration is required:

  • Dates TBD

4. If you are an arborist, be an Arborist-on-Call during an inventory work day

If you are a professional arborist with excellent tree identification skills, volunteer to be an Arborist-on-Call during an inventory work day. Arborists-on-Call check in with inventory teams to problem solve and answer questions about tree identification, condition assessment, high voltage wire recognition, and other questions that may arise. Volunteers will need a cell phone and bike or car. Advance registration is required and a training guide is provided.

5. If you live in an inventory neighborhood, join your community’s Tree Team

In addition to collecting tree data, Tree Teams in each neighborhood are responsible for securing locations, advertising, and recruiting volunteers. After inventories are complete, they will also work with their communities to create neighborhood tree plans to steward the neighborhood’s tree canopy. If you live in one of the neighborhoods and are looking for a long term commitment to improve your neighborhood’s urban forest, joining the Tree Team may be for you.
