Join Green Tukwila to kick off the fall season at Duwamish Hill Preserve, as they clear blackberries and make room for the planting season. The unique ecosystems at the Duwamish Hill Preserve highlight oak savannahs, camas prairie, wet sedge meadow, and the tule wetland. Did you know that the hill itself is a geological wonder and is older than Mt. Rainier? All ages are welcome, but children 14 and under must be accompanied at all times. Bring a full water bottle, snacks, gardening gloves if you have them, and closed-toe shoes. You’ll want to wear clothes to cover your arms and legs as well, since blackberries can be scratchy. Register now to join the event.
