Brookfield Zoo Tree Guide

Did you know that Brookfield Zoo is also an accredited arboretum?

Since the opening of Brookfield Zoo in 1934, the Chicago Zoological Society has had an international reputation for taking a cutting-edge role in animal care and conservation as well as providing a unique and natural experience for guests to enjoy via our many trees, flowers, and foliage. Our expansive walking trails offer visitors picturesque, tree-lined walks, and the zoo's historic Roosevelt Fountain is surrounded by an array of color thanks to blossoming flowers and plants awash in pollinating bees. The zoo's vibrant and flourishing landscape includes both native and nonnative trees.
