Network Tree Inventory Program

About Our Program

In 2023, California ReLeaf secured grant funding from the U.S. Forest Service and CAL FIRE to implement a brand-new statewide Tree Inventory Program to support nonprofit tree planting and tree care efforts across the state. California ReLeaf’s Tree Inventory Program provides ReLeaf Network Members and grantees FREE organizational user accounts to PlanIT Geo’s TreePlotter Inventory software under California ReLeaf’s umbrella account.

In addition to tree inventory software access, Network Members and Grantees receive training, resource guides, and technical support. Scroll down to learn more about the benefits of inventorying trees, program eligibility, application information, and upcoming training dates.

The ReLeaf Network Tree Map is our collective map of tree inventories from California ReLeaf Network Member Organizations participating in our statewide program. We invite you to explore the map to view individual Network Member organization’s inventories. In the summer of 2024, you will also be able to view the ecological benefits of the trees inventoried, including data about air pollution and stormwater reduction, carbon sequestration, and energy savings. 

What is a Tree Inventory?

Tree inventory surveys provide information about individual trees planted and/or managed by an organization. A tree inventory provides critical information about these trees, including but not limited to tree species, location, health, age, size, funding source, maintenance needs, etc.

Inventories allow organizations to collect and share valuable data on trees they plant and care for, including the eco-benefits those trees provide to their community. Tree inventories are also an assessment tool, helping organizations make data-driven decisions that improve their tree planting program – especially concerning tree survival. Simply put, tree inventories tell organizations what they have and help them identify ways to improve how they plant, care for, and manage trees to help them stay alive and thrive.
