Our Partners

Planting trees with the Timbers


We all need clean water and clean air, and it takes a lot of people to plant and care for our urban forest. Environmental Services partners with many organizations, businesses, schools and other agencies to plant the right trees in the right places. See our Recent Projects (link) page for examples of some of the work we’ve done together.
