Connecting and Empowering Communities Through Map Guides to Inventory Trees Within Their Communities

As cities try to mitigate the effects of rising urban heat due to climate change, many have turned to creating Urban Forestry Management Plans (UFMPs). However, UFMPs require extensive tree inventories that catalog trees to assess management costs, tree health concerns, and potential hazards. Creating tree inventories can be prohibitively expensive and a barrier for communities with fewer resources. Therefore, many municipalities have turned to volunteer-led community-based tree inventories, which can alleviate data collection costs. However, managing volunteers can be challenging over large spatial scales, requiring careful planning and resources for guiding participation. Proactively creating ‘neighborhood maps’ that guide volunteers would be helpful, but there is a lack of open-source documentation on how to plan and create such guides for volunteers to use during an urban tree inventory. Through the Grit City Tree Count project, we used ArcGIS Pro and created 24 neighborhood maps across Tacoma using accessible, cost-effective methods based on city published Right-of-Way (ROW) maps and Google Street View. Additional guidance and metrics were added to these maps, including highlighted streets to follow, hazards to avoid, meeting locations, known trees, street names, accessible restrooms, and any other vital information for volunteers conducting tree inventories. Sharing these methods for guiding volunteers will help city managers interested in delivering cost-effective alternatives for urban tree inventories and help empower communities to start their own tree planting initiatives or UFMPs.
