To provide multiple ecosystem benefits, students on our Learning by Leading Waterway Stewardship team are creating riparian (water edge) habitats around the newly constructed weirs throughout Phase One of the Arboretum Waterway Maintenance and Enhancement Project. Concrete and rock-ﬁlled, wire baskets (gabions) previously lined the banks to provide erosion control. Those hard edges are getting replaced with native rushes and sedges that provide erosion control, increase water and habitat quality, and enhance the beauty of the Waterway.
The roots of these plants bind to the soil along the banks and prevent it from being washed away, absorb pollutants that ﬂow into the Waterway, and serve as a new habitat for many species.
