As a 501 (c)(3) non-profit organization we rely on community support to help maintain and grow our collections and numerous educational programs; such the popular children’s Nature Day Camp, and community events like ArborFest and Luminaria. Sponsorship of the Yakima Area Arboretum provides the unique opportunity to connect with the diverse populations of Central Washington and those who visit our community.

Why sponsor the Arboretum? Established in 1967, the Yakima Area Arboretum is a 46 acre living museum, housing the largest and most comprehensive collection of trees and woody shrubs in Central Washington. We are a community hub whose mission is to inspire people of all ages to discover and connect with nature. Each year over 45,000 people visit the Yakima Area Arboretum, to walk the grounds, take a class, take photos, get married, volunteer, attend an event or meeting, to learn, relax, play, and explore.  We are proud to be a cherished part of our community.
