Wildlife is abundant within the Arboretum. Our water garden is home to a population of threatened western pond turtles, as well as a number of amphibian species. Mammals found here represent a broad cross-section of the diversity that can be found in our region. A visit in the warmer months reveals the diversity of insect life as well. Dozens of species of dragonflies, damselflies, native bees, grasshoppers, butterflies, and others abound. The Arboretum is one of the most popular birding sites in the area, playing host to a wide array of migratory and resident song birds, raptors, and waterfowl. Bird walks are held on a monthly basis.

Though most of the Arboretum is dedicated to the preservation of native habitats, there are some very attractive planned and planted gardens. The Patricia M. Baker Memorial Wildflower Garden is a 2-acre garden in the River Meadow showcasing the rich beauty of the Pacific Northwest’s native flora. Other planted areas include an entrance garden with 89 species of woody plants including 57 Rhododendron species and 13 native and introduced tree species including maples, oaks, magnolias, pines and Metasequoia.
The Arboretum is committed to using an ecologically sound approach to all aspects of site development and maintenance. Habitat management actions and methodologies are guided by our Habitat Committee.
