In 2021, Tulsa has been recognized by the National Arbor Day Foundation as a Tree City USA – for the 28th consecutive year.
In partnership with "Up With Trees," the City will celebrate Oklahoma Arbor Week this year by planting two trees at the Tulsa Arboretum on Thursday, March 25, at 9 a.m. at the Woodward Park Tulsa Arboretum. Officials will also announce a beautification project at the Arboretum. The "Arborize the Arboretum" project is funded by a grant from the Department of Agriculture to the City of Tulsa's Forestry Division.
Along with the new trees, the project includes replacing the tree plaques at each tree's base in the Arboretum.
