Commemorate Earth Day and Arbor Day as we plant trees in the park. We will meet in front of the Ecology Center for instruction and supplies, then head out to areas in the park for planting. All equipment will be provided. Volunteers under 18 must have a waiver signed by a parent or legal guardian before participating. Volunteers under 16 must be accompanied by a supervising adult. Pre-registration is required. Please dress for the weather, and bring a water bottle and footwear that can get muddy.
