Walking around your neighborhood, do you see spaces to plant a tree, street trees in need of maintenance, and neighbors who are concerned about their trees but don't know where to begin? Through the Tree Inventory Project, Urban Forestry has helped Portlanders take action to improve their community's street trees, one neighborhood at a time. 

The Tree Inventory Project began with a pilot neighborhood street tree inventory in 2010. Through its completion in 2016 the project grew in leaps and bounds, and many neighborhoods have partnered with Urban Forestry to inventory street trees and create action-oriented neighborhood tree management plans. Volunteers identified, measured, and mapped over 218,000 street trees! Street tree inventory findings are available here. Starting in 2017 the project continues with the parks tree inventory. 

Active neighborhood groups interested in trees began by gathering volunteers to help conduct a street tree inventory. Volunteers are guided by Urban Forestry staff, who provide training, tools, and event organization. Together, information was collected on tree species, size, and health. Data were analyzed by Urban Forestry staff, and findings presented to neighborhood stakeholders at an annual season end Tree Summit in November. Every year at the summit, neighborhood groups worked to develop tree plans: working neighborhood tree groups set achievable strategies to improve existing trees, expand tree canopy, and connect the neighborhood with city and nonprofit resources. The resulting Neighborhood Tree Plan used inventory findings on the current status and health of neighborhood street trees providing recommendations for specific neighborhood actions to improve canopy. In the past, neighborhood groups have organized pruning workshops, secured funding to widen small planting strips, and planted street trees.

More than just producing data and a tree plan, the Tree Inventory Project brings communities together. Participating in the tree inventory project is a great way to meet your neighbors and connect with others who value our green resources!
