The mature trees you see in Riverfront Park were part of the planting effort by Expo '74 planners 50 years ago. For the Expo '74 - 50th Anniversary Celebration, Avista is teaming up with The Lands Council, the City of Spokane, and the Spokane Conservation District for a whole week of SpoCanopy tree planting culminating in an entire forest of urban trees: the Expo Forest. Each day, volunteers will plant 100 trees in areas of Spokane and Spokane Valley that need them most, totaling 500 by the end of the week. Local food trucks will provide meals for volunteers, courtesy of Avista, as a thank you for the help from our community. This effort is part of the broader SpoCanopy program, which aims to increase Spokane's canopy cover to 30% by 2030.
