Harwood Creek has seen many changes since we formed the Garber Park Stewards three years ago. At our first Creek to Bay Day in 2010, our hardy group of volunteers attacked with gusto a 10-foot high wall of Himalayan blackberries and managed to free part of the creek of this highly invasive plant. Two years later, thanks to our ongoing “blackberry bashing group,” the blackberries covering the creek are gone.

A group led by Frank Tsai celebrating President Obama’s Day of Service went after the infestation of Cape Ivy in and adjacent to Horsetail Meadow near the upper bridge on Harwood Creek. After three hours of pulling the ivy out of the trees, shrubs, and meadow and filling 22 bags, the native plants, especially the native blackberry, have a chance to grow. While there is still much Cape Ivy in the park to keep us busy for a long time a big impact has been made.
Meanwhile, the other group, lead by Lech, were actively engaged in the Passive Restoration Workshop at the Measure DD area. Passive restoration uses on-site resources (seeds, vegetation, debris, organic matter) to improve habitat conditions for target native plants. In Garber, we are very lucky to have well established and thriving colonies of native plants right next to the planting area. We learned how to “harvest” five native plants that grow in abundance in Garber (California Blackberry, Osoberry, Willows, CowParsnip, and my favorite plant, Thimbleberry), each with its own set of propagation techniques. Working in teams, we collected and planted across the hillside, finishing by watering and identifying each new plant with a flag.
